Virtual Light Projection

[joelly3d]

I want to throw a texture map as a light source onto the surface of another object. The same way physical projectors are used to do projection mapping onto buildings.

What is a logical VRay approach to achieving virtual light projection. Would it be just using a standard vray light with directional on 1?

use a standard max spotlight set to rectangular. faster and simpler.

Okay, that was my conclusion as well, didn't know if there was a better way that had benefits I wasn't aware of..
