GPU & 2D Grid texture problem

Hey everyone,

I’m using a simple grid texture on a flat plane and control the grid repetition by nesting + Repeat UV and adjusted the planar mapping size of the plane.


Since I upgraded my GPU recently I would like to use it for rendering but using a Repeat UV of 10,10 results in missing grid lines like this:

A repetition of 5,5 works fine (but everything above that doesn’t):

Maybe someone could help me with what I’m doing wrong here? It works fine in CPU mode.

Kind regards

Looks like the grid lines become narrower than 1px, when above 5x5. Try increasing the GPU sampling size

Thanks for your reply @Nikolay. The Vray settings often confuse me - could you tell me where I can increase GPU sampling size? The size hint led me to increase the u&v width of the nested grid - that also works :slight_smile:
