PIXAR “will be releasing a free, noncommercial version of its Renderman package.” “Pixar and Disney are releasing the free version in part because ‘limitations on software access have become a brake on the development of the production industry, and that universal access and a set of common standards and practices can only stimulate greater growth and development,’ according to the product’s FAQ.” In other words, it doesn’t hurt to get people hooked on your software and to have a greater pool of skilled applicants for your job openings. Anyway, free is free.
