3Delight is a fast RenderMan-compliant renderer featuring multi-threading, ray tracing, global illumination, motion blur, depth of field, programmable shaders (RenderMan Shading Language support), quality antialiasing, and antialiased multi-depth shadow maps. It is available for a wide variety of platforms, including Windows, MacOS X, Linux and IRIX. The latest version of 3Delight (version 5.0) comes with a Maya plugin. But what about Blender? Recently, osxrules released for testing the much anticipated 3Delight to Blender export script on elysiun.
Please note: The first license is free and doesn't include support. The non-licensed version of 3Delight is only meant for testing and will have a 3DELIGHT watermark displayed across each rendered image. There are no other restrictions on the test version.
