I need to know, what renderer has been used in the Sintel project. I think it wasn't default Blender Render because default Blender Render renders in horrible quality (If it isn't correct please correct me) . And I need to run it on 64-bit operating system (W7 HP) in blender 2.60. What I was searching, the best was Sunflow yet. What you think about / do you have any better suggestions?
I'm pretty sure they did use the blender internal renderer. Using proper lighting and materials you can get an excellent quality out of the blender renderer. If you are using one of the most recent blender versions you also might want to try the cycles renderer. It ships with blender but is still in beta. But without decent materials and lighting, no renderer will give you satisfying results.
