overbright or invalid color

[YoyoBoy]

Does anyone know why the materials in the attached library cause VRay to write in the log "warning: Material returned overbright or invalid color..." ?

I believe this is related to the problems I complained about a couple weeks ago where my IR map pass was getting hung up on objects with these materials.

Thanks

I couldn't reproduce the issue with any of the materials inside the attached library - it would be better if you could send us reproducible scene.
