I don't use Blender, so my admiration is from a distance but: Wow - what an impressive project. At least if I understand it correctly, this is a real pro-level piece of free and open software that's equivalent to thousands and thousands of dollars in closed-source commercial software.

For those of you who get value out of Blender please consider donating: https://fund.blender.org/ :)

It's a wonderful project. Even small amounts help. Thanks!
