Correction to the message above:-

In his aqualung's breathing tubes, there are 8 equal corrugations in each Poser jointed part, and all joints between polygons are welded. Each breathing tube is an IK-chain set to ON, and has the curve property. As easily seen, the corrugation valleys which are at the boundaries between jointed parts, render wrongly. This fault has plagued my scuba diving rendering from Poser 3 times all the way up to my current Poser 11. The same fault happens with displaying. I suspect that this fault happens by Poser unwelding the polygon faces at all joints between Poser jointed parts, and then working out how to smooth the polygon faces for rendering, and then rewelding the polygon faces at the joints (even where they were not welded before). Has this fault been cured in Poser 12? If not, will it be cured in Poser 13? Other users have complained about Poser rendering faults at the lines where two jointed parts meet..
