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 rewelding them, 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..

Same image but showing polygon boundaries.

Hi Anthony, I did a little test whipping up a corrugated tube in Wings3D:

The tube has four parts/bones.

Did a very simple rig in PP-2014, but I can see no rendering errors where the bones connect:

No problems in preview, either.

Could it be you didn't delete the "cap" facets where the bodyparts connect when you modelled the tube?

This usually gives a welding error where two bones / bodyparts connect:

That's a good point JoePublic. Is Poser respecting those edges set to hard? OT but just curious.

I try to be as "minimalistic" as possible with my modelling, so I use them all the time.

To JoePublic :: There are no cap facets on the ends of the jointed segments of the breathing tube.

Poser seems to render each jointed segment of the breathing tube as if that segment was unwelded ftom the segments that it is jointed to.

Note that in this render, the breathing tube is an IK-chain, and all its parts have the Curve property.

I've seen that sort of problem when a morph has pulled the weld-seam geometries of two actors apart.  I would guess that the Curve setting is creating the problem somehow, effectively pulling the edges apart as it applies the curving effect.

I assume you've tested this with Curve deactivated and/or IK turned off.  Does the problem continue when those settings are changed?

What happens if you switch the figure skinning method from Traditional to Unimesh?  What if you apply subdivision?

The order of channels in the cr2 can sometimes create odd joint effects.  If you try moving the Curve channel listings around in the Channels section, that might have some effect.
