I've been working on these same 3 models for a year now, being delayed by Blender features really.
I'm nearly done with them finally since Blender 2.61's weighting isn't bad so I was able to correct a lot of anomalies.
MY LEG (Ballistic)
MY CLAWS (ChaosUT2)
Also I may request that you don't post screenshots in the quotes (as I know some people will reply by quoting a post), thanks. I'd like to keep the thread managed in bandwidth usage.
I'll release a beta soon, probably a bit reduced in texture detail to keep the size down as it's functionality I want to test.
