Illumination to ramp

[Anonymous]

Hi,

I’m looking for a way to gather the diffuse illumination on an object and pass it into a ramp node. Is there any way to achieve this, or emulate it somehow? I’m looking to control the colour of shade/highlight per object.

I have so far achieved the right look by applying a gradient map to the diffuse shading in Photoshop, but now need this to appear correctly in reflections. I guess I could also bake out the shading per object, but this doesn‘t really give me the flexibility I’m looking for at this stage.

Any response will be greatly appreciated!

Best regards,
Rob
