Say I have a projector and a cube with a separate shader. Projector is projecting a color onto some of the cube. Is this modified color accessible in the cubes shader?
No thats not possible.
The projector is rendered after the cube and additionally it does not modify the cube, it draws independently on top of it (or anything affected)
Still new to shaders but that is pretty much what I was expecting.
How about this. Say I want a bunch of objects to render pure black but places the projector hits are rendered normal as if removing this coat of black and letting the objects texture show thru. kind of backwards I guess but could this be done?
It is possible to do with an image effect.
EDIT: On the second thought, why dont you just adjust your ambient and other lights to absolute black and put a spotlight same size as your projector? This would give you the same illusion.
I had thought about spotlight also but i don’t really want the object full lit. I want it to respond to other lights in the scene and this just uncovers the blackness to reveal the objects true texture.
I’m not even sure if projectors are what I want. I don’t have pro yet so I can’t do image effects. I will look more into lighting solutions but do you know if with pro I can make a custom light that’s not exactly lighting the object but performing other material manipulation?
sorry if all of this sounds dumb but I appreciate any insight.
