tileable projection map in lights

Recommended Posts

I have a simple scene with a direct light. If I add a texture to the light it does not tile the projection texture like expected. 

How could I achieve a tiling of the texture instead of just black color ? That would be very handy for stuff like caustics projection or whatever when you dont have extreme large texture maps. 

Thank you!

Jon

If you have access to Redshift, their lights support uv wrap and mirroring for projected textures.  Maybe there is a way to tile the texture in COPs before using as a projection in Mantra?

Hm no I search for a solution with mantra renderer. I could tile the image in COPs but then I just have a tiled texture in the same spot.

I want the light to iluminate the same area than without the texture.
