VRayLightMtl on one face of a cube, possible light leaks on other side or not?

[Morne]

Hi all

So, if I have a cube, and make the one face a VRayLightMtl, what are the chances of problems on the other side of the cube for light leaks etc?

It should be ok, I think, especially if you use the direct light option for the VRayLightMtl material.

Best regards,
