I use 3ds Max 4.2. I also use Body Studio 2.0 which allows me to open the Poser Engine within Max and run Poser scenes usually with human animation in them. Even though I have Character Studio, I find this easier. Also, Poser has the best pool of characters and textures. Also, Poser 5 has hair and clothing animation now. In Max, they require expensive plugins. I also am using Life Forms to work on pure animation in conjunction with Poser and Max.
