I think the simulation time is pretty good. It looks like it is simulating much faster as the cloth room (probably because it is multithreaded)

So the general procedure is that you set up the animation in Poser. If you have dynamic clothing you start from the zero pose and with conforming it does not matter. Then you enter your sim program, define what is cloth and figure, specify which parts of the figure and cloth need to be dynamic by selecting the vertices and then you run the sim. After that you export the sim and it will be available in poser as a clothing sim (through dyn files)

So a few questions pop up now.

Can you have multiple sims? (more than one figure with cloth and hair)

Is there an equivalent of "choreographed" regions - so you can perform something like lifting a dress?

Does it read the morphs as well during simulation? (opening a shirt with existing morphs)

Is the resulting simmed version of the figures and props still standard poser figures and props?
