Quote - In my naive mind, I would like the poser meshes/figures to be solid objects that are aware of each other and would therfore know when another object "bumps" into them. I guess there are a ton of 3d calculations to make this come true.  Maybe in a future version? I think zbrush has solid 3d objects and when you move a zsphere it will not penetrate another zsphere.

So I pose the figure and then fix the hair...That'sthe way to solve the intersecting problem. Every time the pose changes, the hair may have to be changed too. I was hoping for an easier, generic solution. No big deal, one more thing to play with.

Indeed this would blow your circuits. Spheres are easy, of course, in a vectorized world. Poser does use grid definitions and can have collision possibilites, and with PoserPhysics you can do even more. But that is still collisions between (bounding boxes of) objects, and not on mesh level.

You may try to clothify the lower part of the hair and use the cloth room. Strand hair can do collisions, but it is very slow due to the many polygons. You may consider a 'proxy', that is a very rough mesh conforming figure that you use as collision object for the hair. Make it invisible before render.
