Softbody collides but falls through other softbody

[elijah]

Hi!

I'm trying to implement interaction between two softbodies. In my case a patch falls from the sky on a girl model (also softbody but with mass=0 for each vertex to make it static right now). After patch collides with girl it immediately starts to fall through girl's model. Obviously it's not what suppose to get, look at the screenshots. I can't figure what I'm doing wrong. Help me please.

Both model's have FV_SS collision flag like in Collide3 SoftBody example. Also I call generateClusters(0) on both.
