Well it's not exactly a render, but I've been refining some joints. And I discovered my recording software will make gifs, which means I don't have to faf around with photoshop's timeline and a million printscreens. Yay!

If the forum will let me upload a gif... Here's his elbow bend, 100% weightmapped and base resolution:

It stops at -85, because that is where I'll put in a JCM to create the compression morph that happens when the forearm compresses into the bicep in a crunch, like putting his hands on his chest. Weight maps can't really do that so morphs are necessary unless you like the look of intersecting geometry. Personally I don't.
