Construct 3 3DObject Plugin - SDK V1 only

Download Now

This plugin loads a 3D Model into Construct 3, similar to the new built-in 3DShape plugin, but the 3D object can be a more complicated 3D model, loaded from a 3D model file format and texture. It also supports 3D animations.

It only supports gltf embedded and glb formats (preferably with an embedded texture in the file, a separate texture png file can also be supported.)

Please leave feedback or tag @kindeyegames on X or Mikal in the Construct Community Discord.

Known issues

  • The bounding box may not fully track the model with rotations.

3D Model file requirements:

It's highly recommended to set 3DObject projects to 'regular' z-axis settings.

  • It's highly recommended to set 3DObject projects to 'regular' z-axis settings.
  • Must be gltf/glb embedded formatand embedded texture (png, jpg formats are ok)
    • The texture can be embedded in the gltf/glb or supplied as an image in the c3 editor, but the gltf/glb file must have a material referring to a texture if it's not using a solid color.
    • Do not include other non diffuse textures (e.g. normal map, bump  map, etc.) in the gltf/glb embedded files if possible, they are not used, but would still take up memory.
  • It's highly recommended to set 3DObject projects to 'regular' z-axis settings.
  • Be aware of the 0,0,0 origin relative to the model center (affects rotation center and position.) This can be changed as needed with the Set local center ACE.
  • Be aware of the relative scale of the model in model units. This can be scaled up/down with the Set scale ACE or property and xScale, yScale, zScale (note that these are divisors, to match C3 zScale property.)
  • 3D models are available on CGTrader and Turbosquid, but you may need to find the ones that have gltf and texture support. If there are multiple textures, usually look for the ones labeled diffuse or albedo. These will be the base color textures (e.g. not normal maps, bump maps, etc.) You can only use models that have one diffuse/albedo texture or multiple textures. (If you have expertise with blender you can load a model with multiple textures and then bake them to a single texture and export texture in the gltf embedded/glb file.)
  • If a model you use is not available in gltf file format, try loading the model into blender and exporting with thegltf embedded orglbfile format.
  • Merge multiple animations into a single file gltf/glb file.
  • If you are importing fbx to blender consider using plug-in to improve fbx import to blender: https://blendermarket.com/products/better-fbx-importer--exporter

Debugging 3D models

  • Load gltf/glb model into: https://sandbox.babylonjs.com/
    • Does it render correctly, have texture, animate correctly
    • Check textures, material, animations
    • Check scale
  • Load model in https://gltf.report/ - check for errors / validation
  • Check the 0,0,0 origin point of your model in a 3D modeling program (e.g. Blender), center your model as needed.

Performance notes

  • Use just a few low polygon models (in the low thousand range, if you have a lot of models, move to the low hundreds range)
  • Animating models require additional performance
    • You can control the animation rate to reduce the required CPU performance.
  • Bake down to a single texture (using 3D modeling tool like blender)
  • Use solid color models without texture (will save texture memory).
  • Use a smaller texture map to save GPU memory (2k x 2k texture takes up 16MB, 512x512 is 1MB)
  • If you are baking texture in blender, consider also baking in AO (on model only), this can give more depth to the model. AO Tutorial

Some more (From @meta comments on CC Discord)

  • Do fake shadows with just sprite
  • I you want shadow and light formations in your 3D model texture, you need to texture bake with combine bake type.
  • At the same time reduce the number of triangles of the models by editing the meshes and investigate this bake type as high poly to low poly bake.
  • You will see more things. The result you need to achieve at the end of the day is to achieve a 30k poly effect with low poly models with wonderful baked textures reduced from 30k tri to 1k tri.
  • I suggest you to design your whole scene in blender beforehand and do the lighting there and bake it, and I suggest you to use only 1 material for each 3D model.
  • Also generally use 256x256 for texture sizes, 512x512 is ideal for things I care about detail
  • See WoW examples for great baking of texture with low poly geometry

Basic usage:

  • Use project setting z axis scale 'regular'
    • This sets the z axis scale to the same scale as x and y, which is better for 3D development (and you also can control the project FOV.)
  • Add a 3DObject to the project
  • Add gltf embedded file or glb file to the project (preferred to include texture in the embedded gltf/glb file)
  • If you are using a gltf/glb with an embedded texture (preferred) set the image editor to a solid color, otherwise:
    • Open 3DObject image editor loads the texture file into the image. Note image size must be larger than the Project's setting for spritesheet size (e.g. 512-4096), resize the image larger if needed in the image editor.
  • Test! You can use the normal position ACEs to move in x,y direction and position related behaviors should work (though I tend to lock the 3DObject with other sprites w/ behaviors using events)
  • To change z position, use the setZ elevation ACE (other behaviors or actions which affect zElevation should also work, e.g. sine behavior, drag and drop, etc.)
  • Set the zHeight to match the relative zHeight of the object (used for C3 3D viewport clipping.)
  • Please post feedback and pix/vid of your tests.

Advanced uses: read the dev logs and look at their associated examples.

A great video from @FozzleCC describing details of how to use 3D models with the plug-in. If this video is useful for you, please support FozzleCC on his Patreon: https://bit.ly/PatreonFoozleCC

Note one change since this video was produced, it is now recommended to embed textures in the gltf / glb files and 3DObject will use them directly from the file, there is no need to load them into the 'image' of the 3DObject. The image can be left blank or filled with a solid color for easier identification in the event sheet.

Could someone create a video tutorial on how to use and explore the 3D plugin? I see updates, but I don't see any information or tutorials.

Now waiting for the next version of the addon because the others aren't supported for the latest c3.

There won't be a SDK V2 version SDK V2 does not support what is needed by this addon, I am experimenting with a different one called rendera on itch, but still in experimental phase (ie buggy)

For Anybody running into Addon issues with the new release, Revert back to an older Construct Update. Click on the Pop Up link when loading your project, Click the link (LTS Release Page), Look for the previous Construct version and go to it, You'll be on an older version (It will instruct you to Update Construct 3) Dont do it.

If it doesnt Work still, Either Re-Install the Addons, If it already is, then the next thing is, Any addon you have applied to your game must align with Constructs 3 Version, Which means you have to go and Re-Download older Addon versions from your Devolper with Older versions of the addon, and make sure it aligns with Construct version.

Goodluck!

Some models aren't appearing along with this error on the latest LTS release: local.html:1 [.WebGL-0x13c001e4900] GL_INVALID_OPERATION: glDrawElements: Vertex buffer is not big enough for the draw call.

Still working for me, can you share an example project with the issue you see?

Sure, https://drive.google.com/file/d/1xXjeDyfm73Fdy21pSnBkzPzg4xeWzxDe/view?usp=drive... 


This model loads on 440-2, and throws up that error and doesn't show on newer versions. 

Thanks, will test soon.

I don't see an error on r449.2, however I do see some strange scaling with this model, discrepancy between editor and runtime (larger).

Do you see an error with that version also?

Yes, I can see it in the layout and not in runtime. With this error:  [.WebGL-0x134004ac000] GL_INVALID_OPERATION: glDrawElements: Vertex buffer is not big enough for the draw call.

Can some one please explain to me how to use this addon? I tried to follow a tutorial on youtube that had me importing the glb file under files. But the guy on the video messed with the properties, even though when I click on the file the properties are blank. I followed the instructions to add the addon through the addon manager and restarted construct3 before doing this. I have no idea what I'm supposed to do. How do you use this? I can't find a tutorial

Add '3DObject' to your project first, then you will see the properties where you can add your file...

Did that, nothing shows up.

Make sure the editor and project settings are set to webgl2, not webgpu.

Set Scale higher 10-20 On 3D Object

Then do

 Y Scale 0.5

X Scale 0.5

Z Scale 0.5

Then Use the  XYZ  on the top to rotate object properly (But most time you dont need to)

Hi, I can read: "DONE Support multiple textures" - But it seems like C3 ignores the 2nd texture on the model. Or it just me?

can you please share an example model

Sorry for bothering you, it seems my model has some issues I need to look into. I just did a quick test, and both textures show fine on the test model.

Hi, I'm sure you already know about this but I believe a change to the renderer made it so the performance of this addon is significantly reduced in versions of construct after r440-2. This is especially noticeable on newer Mac's which used to perform beautifully with this addon. 

I don't really test on Mac much more, but if you can share a test, I'll take a look - when I dig my intel Mac out of mothballs.

The description of the video shows a comparison of test results

Wow, so bad! Let me see what C3 changed.

It's a big problem that Construct3 has removed all plugins other than SDK2. 3 years of work on my game is gone.

I also do not like this. You can keep using older versions of C3 though.

There is no possibility of passing it to SDK2?

no, ashley denied the feature requests to support it

When will you switch to SDK 2?

Not able to, SDK V2 did not have the requested features to support this.

Is this the end for 3DObject?

Hi.
Does this plugin support WebGL 1? Or only WebGL2?  because I tested my game on another pc and here is what I got (my game is not loading) 

Only webgl2. I am curious what type of Pc/OS/Browser/GPU does not support webgl2 these days.

My game was okay, but I recently came back to it, and it is not loading.
Please help.

btw I'm using r449 construct 3

Please update to latest version of 3dobject for later versions of C3.

Thank you. I installed 3DObject-2-78-0.c3addonversion and now everything seems to be ok.

Hi, love this addon!

I read this comment of yours......

This add-on will not be ported to SDK V2 (but an LTS version of C3 that is compatible with it will be available for use for quite a while).

I am working on a new, similar addon with more capabilities, which is working with SDK V2 now. I will announce here when it is ready (it will take a bit to get to the same feature set, but it already supports PBR texture and normal maps.)

Any news on when this will be available please? 

Phill

I am slowly working on this in my spare time. It is open source, so others can work on it. I need to update the latest state to get it working again in C3. I did add shadowmaps to it, in my test environment. However, not yet integrated with C3 addon yet.

ok thank you! Do I keep a look out on this web site for it?

When it's ready I'll make a dev log post

Hey there! Thanks for the plugin, it has opened the doors to a lot of cool opportunities. However, I'm having issues after I updated to the newest version of construct 3, and can't seem to find any working solutions.

Issue A:
After updating, objects in the project stopped using opacity values. Meaning any opacity related events, like the 'Fade' built-in addon just don't work. Any objects with a set opacity are also now just set to 100 aswell. For this, I am using both the latest versions of construct and the addon, and have tested on multiple browsers/machines with a friend.

I really only noticed the issue after I tried to export as an html, as before that I believe it was working as intended. However, now the project is bricked unless I find a fix for this.

Issue B:
In trying to get around this, I backported construct to beta r448. Opacity works in this version however any layout with a '3D Object' opens in debug to a black screen, reading 0 fps. I've tried using both r448 and r447, given they are both versions I've used while making the game. I've also tried multiple versions of this addon (specifically 2-77-0, 2-76-5, 2-76-2), all of which cause the 0 fps bug.



If any more information is needed, I am happy to send whatever. I don't really know how to read logs in construct, so that's the one place I haven't checked. Any help with this. or if there is a easy fix I've missed, would be much appreciated. Thanks!

I experienced the same thing, working on an old project in the latest version of Construct cause the opacity parameter not working.

perfect! its already solved, thank you for responsive update really appreciate it

The issue is that C3 recently changed how their webgl2 renderer handled opacity and color and they changed how the vertex and fragment shader interfaced with it. In the end it will likely be a good thing, since it could improve performance for rendering standard C3 objects with varying opacity and color.

I will take a look tonight and see if there are changes possible in 3DObject to support this.

Hi! Thanks for the timely fix. I'm personally still having issues with opacity after updating however.

Layouts without 3DObjects don't render opacity, alongside one's that have 3DObjects. Maybe I'm doing something wrong with the static geometry, but I can't find the setting outside of setting it at runtime on start of layout (which still doesn't fix the issue).

(edit: Just tested BIN712's example layout again after updating and can confirm it does not work there either, both without and with setting the 3DObject's static geometry at runtime)

Any advice or info is much appreciated! Thanks!

yes already try it, and still having issues

Don't set both, only set one or the other. Can you please send a small project with your bug reproduction?

Hi! First of all, I want to thank @kindeyegames for such a great tool — thank you, you are the best!!!

I have a problem with enemies. Specifically, when there are two or more enemies — if I create just one enemy, all animations play correctly as intended. But if there are two or more enemies on the scene, an animation like death for example, only plays on one model.  "for each" doesn't work in this case.

Is it possible to make each model play its own animation separately?)
Video demonstration of the problem:
 https://drive.google.com/file/d/1RAP7pqHRVGX9iK5E0JA5SnjUNNBaIuTv/view?usp=shari...

You might find this interesting, I’m creating a 3D game about mechs in Construct 3. I'll be uploading the development progress on my YouTube: 

Looks great! Let us know how it goes.

Yes, each instance can play a different animation. i suspect it is a 'picking' issue in the events.

I see you are already getting a lot of replies about the newest beta builds. 

This is the one I am getting in Chrome.  as for a test project it happens in a blank project with only a 3d object in it.

So what is needed in SDK V2 for this to work?

This looks like you are using webgpu not webgl2 for the project.

SDK V2 requests were denied by Ashley.

did he say why?

As for the webgl2 thing. I disabled WebPGU. I assume when it says webgl, it also includes webgl2?

The gist is he doesn't want to do more development on 3d.

That error looks like webgl2 is not available. Can you show some of the earlier parts of the log where it shows the C3 initialization and what renderer c3 is using?

I guess that makes sense. Construct is a 2d engine after all. Still a shame though.

As i thought - It is webgpu not webgl2, change project settings to not use webgpu.

runtime.js:1 [C3 runtime] Hosted in worker, rendering with WebGPU [nvidia/lovelace]

is it possible to realize the parameter of 3D camera rotation by Z?

Yes, you can rotate camera around the z axis. I recommend looking at the Construct 3 manual page on the 3DCamera object, check out some of the look at ACEs (you'll need to use math to calculate the rotation)

i love use this plugin. Will there be an update for SDK v2 in the future? because I got a notification like this, in the future if c3 removes the addon sdk v1, will this plugin also develop?

no, sdk v2 did not get the requested features to support this addon

I don't see it on my simple test projects.

If you have a test project for me to try, please share.

i add one GLB model file and nothing more, preview cause black screenexample you can download here: https://drive.google.com/file/d/1MRyHZvYAUpO6FdNsrtlAfDboju97Jbee/view?usp=shari...

Also just a heads up, I had to regress from 2.74.3 to 2.73 because it wasn't working on mobile. I couldn't get any debug info because I couldn't get the chrome remote dev tools working to peek at the console on mobile

which mobile? I am working on something for optimizing mobile now, I'll post, so you can try it later tonight 

Getting a lot of these now, my layout looks invisible until I switch to a new layout 
[.WebGL-0x2e4402d20d00] GL_INVALID_OPERATION: glDrawElements: It is undefined behaviour to have a used but unbound uniform buffer.

ok, thanks for the report, I will be able to start looking at this in a week. If you have a test project, that could help.

Can you also tell me what version number you are using, 

happens both on 440.2 stable and 443 beta

I meant the version of 3DObject, but glad also to see which version of c3. A test project will help me debug also.

Latest version of the 3DO, I reinstalled 2.74.3 and it seems to be working, so I'll stick to this version

Got it, will take a look tomorrow. Thanks for the report.

Possible regression in the latest version (2-75-4), videos no longer show (GL_INVALID_OPERATION: glDrawElements: It is undefined behaviour to have a used but unbound uniform buffer.)

What do you mean by 'videos', can you give more context?

As in the video plugin built into C3. I'll do some more testing to see if I can resolve this

I see, if you have a test project, that will help me debug.

Nevermind, Updated it to the latest version of the addon and it works!

The latest beta broke the plugin, my project won't preview unless I delete the 3d object plugin from my project. I looked at the patch notes, they changed the way that things are rendered in order to be more efficient.
The error code: 

canvasManager.js:1Error creating WebGL renderer:Error: Error linking shader program: Types of varying 'vColor' differ between VERTEX and FRAGMENT shaders. FRAGMENT varying vColor does not match any VERTEX varying

I will see if it can be fixed, it probably can.

3Dobject plugins after 2.71 are not installed on Xiaomi brand phones and remain at 0%. I don't understand exactly what the problem is but I lost this version for some reason. Can you re-install 2.71?

I found the version in my backups, let the comment stand maybe it will help to update somehow

Can you please run this on the phone and send back  a couple screencaps of the result (it is typically larger than one screen)

Hi, are there any tips to make the game light when running on mobile, I tried it on Construct3 everything was fine, but when running it on mobile the game became slow

Try lower poly, try worker animation, try lower animation rate.

Try gpu skinning, try static geometry

Can I add outlines to the model? I tried adding outlines to the model in blender but it doesn't show up in Construct 3, does the plugin not support that?

it doesn't support blender shaders, you can try playing with C3 effect shaders though 

Okay, thanks, I will try it

Is there a way to increase the limit of model loads during runtime?  I'm making a multiplayer game and want players to be able to change models.  I can't use "load from prefab instance" because 1) other instances of the player object are treated as extra players and 2) when the host syncs instances to peers, the UIDs are different for peers.  My current approach works great except for the one-load runtime limit.   

I'm also open to suggestions if you have any ideas!  Thanks!

Use a 2d sprite as the main player. So uid never changes. Connect the current model / 3DObject to that 2d sprite. When model changes delete old, create new model and attach it to the original 2d sprite.

In general, I'd also say this is a good game dev pattern, for exactly the reasons you describe. Your model or animated sprite is decoupled from the 'player controller' and you can be more flexible in control vs animation or mode.

Thanks so much for the replies!  This worked.  I was using a 2d sprite for the controller originally, but I had it in a container with the model for ease of referencing so I couldn't destroy the model without destroying the player controller.  Instead of using a container, I added an instance variable to the model representing which 2d player controller it should follow.  This way, I can easily destroy and re-create the model without impacting a player's container.  Your idea to destroy & create new works just as well as the "reload" I initially wanted.


Thanks again, and great plugin!

Great! When you are ready, would love to see some gameplay vids!

Is there anyway I can contact you or send you a demo for troubleshooting. I am having trouble rotating a 3d object along its x-axis. It seems to be rotating around it's bounding box (what I've got) instead of the object's centre of origin (what I've wanted). 

you can send on discord, I am on the Construct Community server.


Did you check the center point of the object in blender?

Hi! I have a question. Is it safe to release a game on Steam using this plugin? I need to clear this up before committing to developing a 3D game with it. Can I develop the game without any issues? My main concern is: once the game is released on Steam, do I need to worry about the SDK? Or once it's released, do I no longer need to worry about the SDK?

Once released SDK does not impact, if you want to change it later after it may impact, but if you just use the version of C3 that you originally developed the game with you will be ok.

Hi, will you release the update with the new SDK for Construct 3?

Not for this addon, SDK2 does not have the requested features to support it.

Uploaded the latest version addon (2-74-3). Upon launch, a pop up msg saying "Error loading GLTF:TypeError:Cannot read properties of undefined (reading 'length') [via Web Worker]" Any idea what this is?

missing file or bad gltf? drop me a demo project if you are still having problems and I'll debug

Thanks Mikal. I reuploaded the files and things are back to normal. However, is there a way to restart an animation. Currently there is only options to speed up, change rate, pause, resume animation. I also noticed upon start of layout, the 3D objects don't appear instantly (delay in spawning). Thanks!

I think you can set animation time, try that. Yes, takes some time to load 3d from files, so the usual solution is to have some kind of loading screen cover the models as they load.

Sorry as I'm a little new to this but where do you set the animation time? I saw set/delete node, blend time, animation speed, rate, pause and resume animation. Since the object keeps looping non-stop, I just want to restart the animation whenever I wanted it to. I'm sorry for being so bad at this. 😔

Looks great, but which is the single addon I need to add? There are like 40 + individual download files here?

look from bottom up, pick the 3DObject* with the largest version number

everything is still pretty much place holder. but the plugin is working great for my tank game. A spiritual successor to BattleTanx .

can scroll the UV for tracks and morph shapes for damage. I plan to have a proper explosion animation for tanks and buildings down the line.

Looks fun! Nice work.

Hello i have 1 object that load different models depending on character selected. The first time works good but for next selections the character still the same. There is a way to unload that model? Stay even when destroy and create again.

Try using instance models, or templates, but it may take more resources. see devlog for examples 

When moving to a new level at some point models stop loading. what could be the problem? with the problem encountered on ios. at first it starts to slow down animations, then after a level or two, stop loading models completely.

Hmm, difficult to know from the description. Perhaps old models are not being destroyed? Can you see the ios console?

I'm testing on iphone 8plus. i don't see any errors in xcode console. cpu consumption within 9-20%, memory usage 50-250 mb, very high energy impact. here is the data i have. plugin version 2.73.0

Can you send me a bug repro project? Does it happen on remote preview on iphone?

You can DM me on C3 Discord to send bug repro (Mikal)

This happens on iphone when running through remote preview in construct 3. It also happens when running on iphone through xcode. Where can I send the project?

Hello. The plugin stopped working on android. What to do?

try revert back to older version when it was working 

The project will not load on the old version

Can you share the issue you see with loading with the old version 2-73-0 (dev console screen when C3 editor reports that loading is not working.) 

Hello Kindeye the last version of the 3D Object 2.74.3 give a black screen when try to preview on S23 Ultra. Dont know why just on that phone. Not happend with the 2.73.0 and older. Do you know what could be the problem?

When booting a project on a mobile device the project simple refuses to load. Is there a workaround?

Hey there! I'm certain that you're aware that the latest update on C3 is warning about this, do you intend to update the plugin in a near future?

This add-on will not be ported to SDK V2 (but an LTS version of C3 that is compatible with it will be available for use for quite a while).

I am working on a new, similar addon with more capabilities, which is working with SDK V2 now. I will announce here when it is ready (it will take a bit to get to the same feature set, but it already supports PBR texture and normal maps.)

It great news, we will waiting you )

Really great news! Appreciate all the effort and skill you put into these tools

Alpha channels are having a weird effect where they clip through geometry behind them. I am using 3d shapes for the smoke effect. the world is a 3d object

Yes, transparency/alpha in 3D, in general, is always a challenge. The better results for simple renderers like C3 are to render in order as much as possible.

Check that the render order is the distance from the camera and all layers are 3D.

If your 'world' is one big GLB/GLTF model, it will be hard to sort properly (near and far meshes will all be part of one model.)

An alternate option is the 'screendoor transparency' in the 3D effect, which has a particular 'look' but will make the rendering support out-of-order rendering better.

DAN

yah the level was one big object. I will cut it up into smaller chunks to help. Thanks

Hello,

Watching FoozleCC, he shows sample code to copy and use. I have no idea where this code is – which sample is he showing/using?

Please use the latest version of 3DObject, and do not use a main.js.
Try these sample projects instead, I will remove the old ones:

  • 3d-object-vertex-color-1.c3p
  • Screendoor-1.c3
  • FogExample-1.c3p
  • 3DObjectFragLight-2-60-0-1.c3p

Hello, thank you for this great plugin, I have a doubt, when I import a 3d object with the texture embeded appears compresed in game.

 If I search the texture manually in construct 3 it shows ok. 

The problem is I can´t search the texture for a mesh with multiples materials, also if I set a mesh as "static" with the texture checkbox marked, the texture appears corrupted.

Any idea how to resolve it? Thank you so much

Do you still have this issue? Please share a project if you do; I'm not sure I understand the problem yet.
