So I've been wanting to put my renders up next to something for a comparison to test for correctness. It'd really be helpful if I could have a ground-truth form of the renders I'm doing. After all, being "Physically Based" sort of implies that it your renders sort of look correct
I've tried some things, and I've heard of other things,
- I've tried Mitsuba, as per MJP's advice, but I really can't get into it. It's good, but the XML is ridiculously obtuse and word-y.
- I also don't like Blender Render because of all the thousands of presets that do things I'm not accounting for. Basically, it's hard to use for just making a simple test scenes to render.
- I haven't yet tried Pixar's now-public Renderman, but I'm going to try that one out soon.
- I've read that Cinema4D has it all, but it's a little on the extremely pricey side
What sort of GI programs do you use, or would recommend, for comparing renders against?
Thanks in advance!
