I have a light with a light function material, that’s basically having the light project an image. My issue is - the light is tiling the image when it’s projecting it, and it’s offset from the center of the light - basically by half. This is shown in #1 in the image… If I move the light, I can sor…

In texture parameters set x and y adress to Clamp - this will remove tiling. In light function material add TextureCoordinate node to texture, and add vector2 (0.5, 0.5) to it - this will make texture offset.

Light function - projected image offset

or create simple scalar (float) and add it. it will work also.
