Hi, the weights seem to be calculated correctly and the detected edges seem to be smoothed as expected.

If you're talking about the broken lines and shimmering in motion, then that's not something SMAA can fix. You'd need to use MSAA to get more stable highlights in a dark scene like this. TAA would likely also yield better results in this case, but that's currently not included inpostprocessing.

For SMAA I'd recommend sticking to the color edge detection with depth-based predication. Use a lowpredicationThreshold around0.0002, apredicationStrength of1 and apredicationScale of2. Also, make sure to optimize your depth buffer range by setting the camera'snear plane to something like0.3 or1.0. This increases the accuracy of the predication. Thefar setting doesn't matter much for this.
