Vray4Nuke Render Issues when using projections

[alvaro.alonso]

I get an ugly red edge outside of the projection area, I’ve tried everything but still can not get rid of it, seems like a bug.

Any thoughts?

I’m using Nuke 12.1v2 and V-ray4Nuke 4.30.00 HWLIC, revision a4fe949a from Jun 5 2020

Hi,

The easiest way to fix this is just by adding a UVTile node on the project3d texture input.
The red color is to flag an invalid UV. When adding this UVTile, the UVW generator that is exported and used by VRay is different than the default one and will take care to “cut” any invalid UV.
