I’m working with some emission properties both with textures and just with standard colors and wanted to know if it’s possible to “cast” light from these emissive objects. I know in something like Unity you could only do that if objects were static and you had a hybrid lighting setup that involved baked lighting.
I was thinking of faking the effect by having a glow layer with the emissive object and just use a point light or something similar with the same color to cast the lighting. Is there a better way to approach this?
Is this satisfactory? I can’t think of another approach off the top of my head. (That definitely doesn’t mean that one doesn’t exist! I just don’t know of any.)
Yes pretty much. So if I created a sphere that had an emission color, I would want to use that emissive color to cast lighting to actually look like a light. From that example, I can see that they added a point light to actually cast the lighting. I was just wondering if there was a way to cast lighting from a glowing object without any actual lights.
nope, this would mostly require ray tracing to work well. The cheap version would be area light which is still expensive a lot so we do not have support so far.
