Gradient textured lights

Hello, I need to create textured lights (light projection) with centieo.
I couldn't find a way to do so. Emission material is not providing the exact look, it is spreading the light too much.
Usually I work with a spot light/ ies light with the desired texture, but centileo seems not liking the texture in light.
Any idea?

C4d physical render with spot light.

The second image is I am looking to recreate but with GI and bounce light.

In Blender Cycles I already did.

I think the projection you are talking about is based on directional textrure mapped to the light source. However CentiLeo emission material texturing is currently used only for changing the area of the emissive surface with different colors and intensities. We need to add this features. However, I would also give a try to some workaround:
1) Create an object with clear glass material (roughness = 0) around your light source.
2) Add a texture to the color of Transmission.
This way you will be able to get a projected pattern you like to on the walls. And the render speed will be quite good too.

Thanks,
I did a render with the glass material, its working. But not the exact look I am after. May be I need to recolor the texture.

The recolor may help, but changing transmission roughness to quite large values may change the noise amount in some gradual way. But it works with the least noise amount on low roughness values.
