View Full Version : (vray) What is causing this texture to 'fade out' into a blurry mess?

See along the roofline, how the texture fades to bluriness? (

This is an obj I made from a dwg file and imported into Maya. My solution has just been to remodel the roof, but there must be something that is actually causing it. And in future to save remodelling, I'd like to find out what!

- I have checked the normals and to my untrained eye they look okay. I have tried 'set to face', 'reverse' pretty much everything you'd normally do to no avail.
- It's a simple planar UV map on the object, works fine on all other objects
- when rendered in Maya software with a checkered lambert, the same roof object renders fine, no blurring.

I have seen this bug in V-Ray before. I don't know if there's a fix yet but it has to do with the UVs, so maybe try a new projection.

otherwise, get the latest nightly build and see if it's still a problem.

Best chance of fixing it once and for all is to send in the roof as a Maya ASCII scene to Chaos Group. Chances are it'll get fixed as a bug like cgbeige mentioned.

I'd be interested to know what the problem geometry topology looks like. If that is just a single n-gon then it would not surprise me if vray struggles to interpret the uv's correctly. Same thing if it has been triangulated to a single point in one of the corners.
