Please forgive me if this has been discussed before or if this is an issue that may be just on my setup.

I did a render in Poser 6 and found that SEAMS showed up on a model. Most noticable at the inside wrist and inside the ankle. I tried another texture and NO SEAMS.

Apparently for my rig, and with the attached light and rendering settings image, textures on a WHITE background will show up the seams. Textures on a filled or similarly colored background to the texture will not. I also noticed some seams in the hair. It may appear that this also affects hair textures.

To test, I selected 18 texture sets; 7 filled-in and 11 white background. The textures themselves range from pale to dark-skinned and these vary within the two groups.

All eleven of the textures on a white background, showed seams.
Six of the seven filled-in backgrounds did not show seams.
The seventh texture with a filled-in background, upon closer inspection, had a light colored seam separating the texture from the filled background, and this showed up in the render.
One IBL used as set above. The light is set to point straight down and slightly in front of the figure.

texture filtering causes seams to appear (i think it does some offset stretching or something, i don't know) any texture done in 3d-painting programs render properly in older versions but have seams showing up in P6 if you have texture filtering on. Some textures have no seams because they're painted way outside the seams on the texture map (depends on the model's UVs too) other than this, i really love P6

Seams are a problem in P5, too. Don't use texture filtering unless you have to. It's generally meant for distance shots, not closeups.

Two reasons to use texture filtering:

1. if you get a "moire" pattern in the distance, with certain kinds of textures
2. if Poser hangs when loading textures, meaning the textures are too big

Otherwise, leave it off. If you're using texture filtering to eliminate noise (in hair textures, say), use the shading rate instead. Change the shading rate of affected object (under Properties). I use 0.02 to 0.05 for Koz's hair, for example. Then make sure shading rate in Render Settings is at least that low.

A lower shading rate will render slower, so don't change the render options shading rate until you're ready to do your final render.

Thanks folks. :)
