Yeah I prefer sharing over discord indeed. Is your name the same there? (I sent a friend request there to Deakcor (I´m jackydoo_11733))

When importing my .blend or .glb file of this scene, there´s nothing to see here.

Dragging or importing over Import shows the same result.

PS: I´d love to be able to insert the path myself here, if the field would allow that.

Alright thank you Deakor :)

(I tried the .glb conversion, but no difference :I)

I import it as a .blend into pixelover.

I´m not sure I understand your second question.  Can you clarify it for me?

(In blender the model looks completly normal. I have control curve objects to animate the model.)

I made screenshots with description.  (I animated my character and one of the animated controls causes a bug with a long forehead stretch.) In restpose everthing is fine. I tested and found out, it must be specific animated controls with trigger the issue. )
