I've seen all of those images showing things such as beams of light passing through a stained glass window. I've figured out how to produce something similar in two ways: through mapping the color of the image to the light or mapping the color of the image to the shadow. But both are really limited work-arounds.

Is there a way to make the color of the light CHANGE TO the color of whatever semi-transparent object that it passes through? Without having to map it to a specific color from the beginning?

The simplest, non faked way is to turn on raytracing :sad:

even with raytraced enabled, that effect is not possible (dont know why), ive been trying to do that effect, but nothing works:shrug:
There is a MR node called Mib _ color_spread, im trying to understand that node, i think that node is the key to achieve the effect:)
