Need help with V-ray black traces problem

[jeanchevallier]

Hi i been to re install 3ds max and Vray and when i try to do a rendering to texture, i get some black traces on my textures.

Do you have any idea how i can fit it please ?

i am using 3ds max 2017 and V-ray 3.40.

Could be firing in the dark here but is it possible it is ambient occlusion or you have some stray vertices/edges? Or overlapping geometry? It all looks pretty clean though.

I see Vray has also produced 3 warnings in the render, what do those warnings say?

Hi Andrew thx for your help

here is another screenshot with another 3ds max scene and you can see better the Vray warnings

Hmmm, I don't know, the warnings are only talking about the Frame Buffer. To me the issue looks like a geometry issue or an unsuccessful UVW Map. I'm asking the obvious, but you have properly unwrapped the model and assigned the correct mapping channel right?

Yes its properly unwrapped and also assigned the correct mapping channel.

How can i check if its a geometry issue ?

But a geometry issue would be strange because i get those black parts on any of my scenes and objects.

And when i do a scene render (Not a rendering to texture) my object dont have those black parts .

It happen only when i make a texture rendering.

And look like its doing it only with Vray and not others 3ds renders like mental ray
