Here's my progress on the rig so far. She's skinned and her arms and legs are rigged. It was a fairly merticulous process, a process which drove me well into the early hours of the morning, but I think I'm getting the hang of it. I found that Alan's tutorials helped a lot as a guide. Also, looking through Ethan's blog and the processes he used to create his rig has also given me a few ideas.
This part of the skinning--the hips-to-thigh connection--was particularly fiddley to pull off.
When rigging, I also created crosshair controls infront of the knees and behind her elbows which control the FK/IK switching.
The fingers were also a pain. It always seems to be when the geometry folds in on itself around joints that things get complicated during skinning.
