it is not vital. but you would do yourself a favour if you bind to the poly proxy. and if you did not do anything on subd level, it is even advisable to convert to poly, rig completely in poly and then convert to subd with proxy object. why? you probably want to have very fast feedback while you paint the weights - and testing every now and then if the weights perform as intended while you move some bones. imagine you decide to animate it in the future - if you only painted the weights for a goodlooking pose, you had to start from scratch to make it animatable.Originally posted by Witchy
Secondly, I rigged a subd character previously but in the references I have they say make a low poly proxy and bind it to the subd surface. I am not animating, just posing, is it ok just to stick to subds and not bother with the proxy? I know it is harder to paint weights that way but as I'm not planning on them moving I just want to check whether it is vital.
