Cloth crashing Maya? Anyone have this problem

[zachkadish]

I have a fairly complex rig, some expressions and blend shapes, Transfering UV's to a subD, With a Lo Rez version of my SubD character, for animating and faster interaction. I try and make the Lo Rez version of my model a collision object and Maya just closes.... Help....

Could it be a memory problem?

Exactly the same problem here. Tried on a few different systems. This is a smooth skinned poly character. When I detach the skin and reattach it to the skeleton the cloth solver works fine so I suspect it is something in the skin weights that is causing it.

Did you find a solution for it?

any pole vector contraints around? since its a known issue!

[xoch]

Actually yes, but removing them does not solve the issue.

Note: I'm using 4.5

After a bit more investigation I found out that the problem is connected to the skeleton I'm using. It's a pretty basic setup with IK SC for the legs, IK RP for the arms and set driven for the fingers. I just exported my unbound skeleton and bound a simple nurbs sphere to it. Created a cloth collission object and the moment I created a garment Maya crashed on me again.

This was without PV constraints.

One thing that could cause it are the local rotation axes, I've been messing around with them a lot so that may be the cause. I'll rebuild the skeleton today using the old one as a template and see where that leads.

Apologies for making this thread longer.

I found the cause of the problem. I've connected 3 custom attributes of a locator to the rotate attributes of the forearm bones of my char. If I break that connection, cloth works like a charm. I added a new locator, added 3 attributes and connected them to the rot values. Enabled the solver and crash right away.

Easy to workaround but it was a pain to figure out.
