Sorry. I have made models myself and I realize that making a model this complex is a lot of work. 0 - The first I've heard of a rendering problem with it. ... 1 - ERC and IK chains do not play well together. IK was built in at first, then based on tests (both in-house and beta), IK was omitted. That proved to be correct. Of my copy that I had put the IK chains in, I made another copy and in the copy using a text editor I deleted all the slaving pointers and all the dummy morphs. After that, a setup with Mike in his scuba gears rendered OK. ... 3 - The model was constructed based on photos of divers wearing their gear. Many manufacturer and safety references were used. sorry again. I live in Manchester in England and most of the scuba gear that I see is British made. My stab-jacket (alias BCD) (real, not mesh) was made by AP Valves at a place called Water-Ma-Trout in Cornwall (UK). (That is a real place name! :-) ) 4 - In order to properly conform the rig to the figure it was intended for, ... I did not conform it, I merely parented it to his chest.
