> I'm glad many big studios realized this in that they either build their own tools (Pixar/Dreamworks) or they adapt Open Source (Blender) and help improving it. Places like Pixar/DreamWorks developed proprietary tools because they didn't exist when they started. Disney/Pixar heavily uses Maya. Disney was one of the first places to use Maya before it was released in the late 90s. Like many other places they heavily modify it. DreamWorks uses a lot of Maya and Houdini, but have proprietary rigging, animation, and renderer. I haven't seen any of those places contribute much to Open Source unless they're driving development. I haven't used Blender much at all. Apps like Maya, Houdini, and Nuke have a lot of under the hood architecture necessary to use in large studios that I hope Blender has, too. Photoshop, for example, is very difficult to build that kind of pipeline around.
