backfacing polygons?

Texture or material nodes?

I don't know exactly.. but it looks like there are two dresses.. one inside the other and the inside one is out of sink with the outer one...  is there a control that has gone out of sink...   for this dress?

has is to do with the morfs..?

sorry...  i'm sure some one will know

its a freebie that was packaged as a .pz3 file. Its not in the material because I tried all sorts of material to it with no success.

Turn off Raytracing, if its on.  If that doesn't work, try the P4 render engine.

Are you using AO? Are yourendering with raytracing or the P4 rendering engine? What figure is it? We need a little more information before we can help you.

Assuming you're using raytracing:

If you're using AO, there is a problem with self-shadowing polygons that can be corrected by increasing the bias on your AO light. If it's a backfacing polygon problem, checking "Remove Backfacing Polygons" in Render Settings should make it go away.

Otherwise, tell us a bit more about the problem.

Judging from the screenshot, you are using Poser 5, so ignore any advice regarding AO, IBL etc P5 doesn't support those... If you're using an earlier version of Poser than P5, then I can't help, so ignore the rest of this post.

The problem looks to me like the dress is made using "2-sided" polygons. P5 has a particular problem with those..

A way to check is to switch to the P4 renderer. If you then notice thin, horizontal black lines appearing (instead of the blotches) then that's exactly the problem.

Alas, there's no way that I know of to cure the problem within P5. (Not to say that there isn't, just that if there is, I don't know it).

The only way I ever found to get round it was a laborious process of:
Export the skirt as a .obj file.
Load the .obj into a 3D modeller.
Select the whole thing and convert to "1-sided".
Save result.
Import saved result into Poser.

You will unfortunately, have lost any boning (if it's a conforming item), but you should be OK if it's a dynamic cloth...

Hope that helps,

Yup, i use Poser 5. Its not a conforming figure. Will Anim8tor work in converting it to a 1-sided object?
