Material in rendered view shown in black


Suddenly all the materials that I create in V-Ray for rhino show in black in the rendered view, I can’t figure out why, I’ve tried re-install the software put the problem remains.

It is impossible to work this way as I can’t map the size of the textures.

Any toughts on why this happened?

Windows has not made any update the last few days. I’m using Rhino 5 SR5 with v-ray 3.4

Thank you.

I would recommend updating to Rhino V5 SR14.
Then see if there’s an update to V-ray.
If that still doesn’t work, the third step would be updating your display drivers.

Any luck?
