3DelightI use an older version of 3Delight with Blender 2.79 for much of my animation rendering( by implementing the script by Matt Ebb). The program renders excellent Renderman compliant images, but it doesn't play nice with rendering the physics simulations in Blender, so for these I use Blender 3.0. But for one free Renderman compliant license this program can't be beat.
