help with self-collisions

#1

Hello, I have a curtain that flows…how can I avoid self collisions…the mesh penetrates itself and goes through itself…thanks for any help…

self envalope

from the docs:

When set to a non-null value, self collisions are computed on the cloth. Collisions are computed by using a volume around the cloth, called the envelope. This attribute defines the size of the envelope for self collisions. When a vertex of the cloth enters this volume, it is repelled outside of the envelope. The parameter defines a size in world coordinates. A too small value results in less accurate collision detections: if a vertex is moving too fast, it will perhaps skip over the envelope. Testing for self collisions is time consuming, use it only where necessary.
Tip: use the smallest possible envelope: this will speed up computations.
