UV borders (black lines)problem

[Dantert]

Hi! I have a big problem with my keyshot pro.
When I ceck the mesh in the viewer all is ok, the uv seams don't show up but if I go to render and make a render, the image that I have as a result shows the uv seams as black lines all over the model, somewhere more somewhere less.
As you can see in the attachments in the preview all is ok(but low res) while in the rendered image there are black lines everywhere.
I made this model in zbrush using a guvtile as uv for the body and uv master for the bandages uv's.
I  really dont understand what is the problem. Is there no way to make this lines disappear in the hi-res render?

Hi

That problem has nothing to do with Keyshot. You just have to raise the uv shells edge padding either on zbrush or photoshop. Auto-uvs aren't ideal either, it's best to spend some time laying the uvs shells by strategically cutting them.

yeah but why the uv's are right in the preview and wrong in the render?
thanks anyway
