Pixar has their own software, most others use Maya or some others use high end program modified to meet their needs. Almost all job posting ask for skills in the programs that they are using. Show me 10 job postings that ask for knowledge of Poser, if you can, and I can show you 100's asking for high end software abilitys. Why would anyone reinvent the wheel? Poser simply does not meet the needs of most 3d animation studios. Skills in Maya, 3d max, Lightwave does. Dale
