Projection mapping using a vray light ?

[stevesideas]

Is this possible ? I can use standard lights and get nice projection maps, but it would be good to be able to use a mesh and turn it into a vraymesh light and then project a map from that light. At the moment Im having to use a lot of standard lights to get that effect.

The V-Ray lights are area lights, so they emit diffusely in all directions. In newer versions, there will be a "Directional" parameter that allows you to focus a rectangle light, but it does not work for mesh lights (this is quite complicated).

That directional property sounds good...Im guessing that wont get into V2.0.

Regarding the mesh light...couldnt that just work off the normal of the face ?

That "just" part is incredibly complicated
