Here is my latest headache -- I cannot get Poser 5 to perform cloth simulations. I am using dynamic cloth props and trying to drape them over a figure. I have done this in the past, and it worked fine. For some reason, now when I start calculating the simulation, it just runs and runs but never finishes. (I have left Poser running overnight, just to be sure that I wasn't being impatient -- and this is for simulations that in the past have taken no more than 10 minutes or so. The next morning, it was still "calculating" without any output.) I've gone through several of the very basic cloth room tutorials step by step, just to make sure I hadn't missed something, but the result is always the same. Endless processing time, no simulation.
