I use the following Ray dream 3D, Amorphium, TrueSpace 2.0. All of these are really good at some things but leave something to be desired in another. for instance...TrueSpace 2.0 is really easy to work with, you can size and shape things by hand or by the numbers and it imports and exports very well, but any object with a boolian operation and poser won't read the uv's (mabey they fixed that in V4.0). Amorphium is ultra-easy but lacks alot in the detail department (there is alot of guess work involved). Ray Dream 3D is nice but I've found that the meshes it produces are not quite real enough for use in other progs. you would almost think they where some sort of polymesh, if you saw one you would know what I'm talking about. Hope this helps!
