Detect when cloth removed from trigger

[neecko]

Hello, 
Looking for some help. I read the docs, but still trying to wrap my head around achieving this. I have tried collision callbacks, but this lags real bad with what I'm trying to do.

Simply all I want to do is detect if the cloth has exited or is no longer touching a simple trigger. I don't want it to interact with it in any other way.

So the green is the cloth. If it is moved off the black box an event is called like ontriggerexit or something of the like.


also on a quick side note, is there a way to detect when and if the cloth was torn?

thanks!
