V-Ray GPU - warning: Export problem for 'Map...

[thepixon]

Hi,

I'm getting hundreds of these every time I start a render. Only V-Ray materials in the scene, so that can't cause it.
First I thought, it comes from materials with translucency as the GPU engine can't handle it, but I surely don't have that amount of translucent materials that can cause 1536 lines of warnings for a simple exterior render.

Any ideas what causes this and how can I fix this?

Setup: 2x2080Tis with NVlink, Win 11 beta, latest Nvidia Studio driver, latest V-Ray (I tried latest nightly too)

Thanks,
David

Hi thepixon,

Please refer to the following forum thread on the matter - hope that helps!

The thread linked above talks about the specific use of the "Blur" field in the "Coordinates" rollout of the VRayBitmap properties, but I've also noticed this happening on materials from the VRay Material Library whenever "Filter mult" is anything other than 1.0, so make sure to check both if it still happens when you set Blur to 1.
