Uv Sewing Problems

[lightmotion-se]

I'm having trouble with UV shell borders inside the polygon mesh.

I have checked the mesh thouroughly. The polygon edges are merged in the normal way.

When, I move a single vertex at the problematic edge, the surrounding polygons change in the right way. So it is not, due to that it would be separate meshes on the different sides of the edge. Because it isn't separate meshes.

I have tried a lot of different way to remove these UV borders. I have used UV merge and sew UV's, but none of them work on these borders. I have sewed a lot of other UV shell borders in the model, but at these few edges, sewing doesn't work

How do I make the shell borders disappear?

I want to remove these borders because they cause problems when I bake textures with Mentalray Global Illumination and Final Gather. At the shell borders, darker unnatural looking areas appears in the baked textures.
Is there another way to solve that problem maybe? Without having to remove the shell borders inside the mesh.

This image show the UV borders inside the mesh:

its inevitable that you bet borders. you should therefore make the fill texture seam paramater bigger.

Yes, I understand that it allways must be UV borders. But, not at that place. I can't see why it must be a loop formed UV border inside the mesh when it's a UV border at the mesh's border as well (the correct UV borders).

I will try to adjust the fill texture seam and make it bigger. Do I make that in the Mentalray parameters?

ok. Hur

Theres a open edge loop between the edges (so your points are merged but the edges arent thus forming a invisible but maningfull hole in between). Separate all into individual polys and merge the seams back together (easiest is to use separate with keep together off, note one of your coners is open you need to merge the one separately). Did you by any chance import the model, if so you shoudl relay check that the imprter isnt buggy.

PS dont post mb files they contain a nasty way to implement trojans.

PPS Free tip when you render occlusion to maps in mental ray DON'T use the occlusion option in the bake dialog, but set up a shader to use fg_occlusion and set the options in render globals with min max distances ok, this will render a better looking occlusion in 1/10 of the time. Sometimes it pans out to know what the computer is doing, and what the developers think (lunch probably)
