Texture stretching at edges

[bobvelocity]

Hey guys,

I have come across a little problem which I've not had before. I've uv mapped a chimney breast and applied a brick texture. All is fine in the viewport and maya render. With VRay though I'm getting stretching in the corners. Any ideas on what this is?

Regards

Keith

Seems to be the subdivision settings added to the shape node.

Did you try to turn off "Subdivide UVs" option?

Probably inserting few edge loops will help to lock down the UV seams on the sharp corners.
The safest solution is UVing at a higher subdivision.
