Thanks everyone for the replies, it sounds like the RNDA file is what I need to look at. I'll try it tomorrow and let everyone know how it goes. That sounds like the exact problem I was having, putting the legs to 60-90 degree angle (which can be done in real life like a double leg karate kick with full extension) then having the left and right buttock part of the figure distort the front leg making the thigh look bigger. I may have confused some people in a mistake I made in my first post. It wasn't the buttock I was having troulbe with, that was the figures actor part name, but rather how the upper thigh would buldge out when bent. I've even seen this on some marketplace pose sets here. That's why I think the RDNA will help. Dr Geep, If you have any tips on sitting poses that would be great. They seem very complex off hand trying to learn how. I already had the TAOP PDF tutorial on posing and it's very good. However, it mentions nothing on sitting poses and information on them is hard to find. Thanks again everyone, I'll let you know how this works out.
