Thanks Cage that sounds like a good approach, looks like I might need to do some remodelling.  I'm ok with making the mesh and texturing, but ERC and jcm I need to practice.

Can I ask if you used seperate groups in the mesh for the left and right thighs? I have mine set that way at present, but I am wondering if, since those groups are so small on my shorts, I might be able to make the whole mesh one group, as hip2. I like to keep things simple if they work. Could you point me to the thread of a week ago that you mentioned, it sounds like I should read it. 

It's getting late here ( in the UK ) so I might not reply until tomorrow, but I very much appreciate your input.

Cheers

Ian
