How to set up Environment variables in 3ds max for V-Ray?

[flame.fish]

Hello,

I wanted to ask how can I add environment variables in 3dsmax that can be used in material bitmap paths to point to texture folders on my disk?

Below a screengrab from VRay help where it explains the use of ${VAR} by V-Ray.

Would it be a *.ini file somewhere that I should edit?

Thanks a lot,
Wojciech
