It’s been a while since we’ve seen Dmi7ry — their last post was 2 years ago.
Welcome back @Dmi7ry !
No. Not really.
We’ve worked on a lot of other things instead.
Also, related but not exactly what you are looking for:
- Sprite trimming to reduce overdraw #4350
- Improved texture compression using BasisU (v 1.2.180)
- Texture Manipulation API #5948 - IN PROGRESS
With Sprite trimming and the new texture manipulation API we have basically everything in place to also add support for trimming alpha from atlas image.
