#Blender 2.91 beta tested... My god, the cloth simulation in sculpt mode is awesome. Collision works great. It seems that it also not crash anymore on my laptop (I didn't test with my desktop computer + NVidia).
I'm impressed, Blender is one of the best example of what opensource can propose. Can't wait the final release.
(But please, try to make Cycles renderer compatible to intel opencl... On Linux, LuxCore does it...)
