Question by danielccamarda · Sep 11, 2019 at 07:03 AM · material realtime emission global illumination cutout

Emissive material inside object with cutout mask to let light out

I have an object with a cutout mask (although this could be changed to a different type of mask if there's a better solution) and then multiple objects with an emission material inside that object that act as LEDs. The LED objects are controlled via scripting so that I can simulate lighting animations. I can get it so that I can see the LED color through the object but I would like the emission to project out of the masked object onto other objects in the scene. If i move the LED object outside of the masked object, the global illumination works and lights up the scene as expected.

It's worth noting that everything in the scene is static.

Is this possible?

using version 2019.2.2f1
