Brecht, you can avoid the worst numerical instability issues of CCD by adding a small repulsion force when cloth is in close proximity with geometry. IIRC most commercial cloth sims do this. Ton, I'm sorry I blew up. Cloth collision is something of a special nightmare for me. Sergej, that's

Hi all, I haven't emailed on this email list before, but I'm happy to see discussion about the cloth simulator in Blender. It is the main reason why I started using Blender, and I know a fair amount of folks in my community (AI and robotics researchers) who would love to explore cloth

To fix the cloth tunneling though the cube, activate "Single sided" in the cube's collision settings and it should work much better. Anyways, during my recent work with Bullet, I tested some things that are currently not integrated into blender. Mainly Bullet softbodies and cloth. Both have

Bullet's cloth system is no replacement for what Blender currently has and I'm not aware of any available library that we could use without having to do a lot of modifications to make it work. Am Di., 20. Okt. 2020 um 12:26 Uhr schrieb Brecht Van Lommel via Bf-committers : > The most important

The most important thing for cloth is that you can get it to give good results in real world cases, and the cloth simulation changes were based on work done for Agent 327. https://www.youtube.com/watch?v=jU6-cI-z8HA In practice you use smaller time steps and the fast-moving cube will get collided

Hi Joe, This is a bit harsh, there have been good cloth contributions to Blender by Luca Rood. The current module owner for it is Sebastian Parborg though. I'd suggest to connect with them to see what steps forward could be. We are also in the process of making a good node physics system to
