Hi
I’d like to create these virtual art installations that use a lot of lights (led tubes, ring lights, spots lights, …) with different kind of shapes. It’s important to have a lot of control on how the light is projected and interacts with the environment.
I’m wondering what the differences/advantages/disvantages are of choosing emissive materials vs creating regular light rigs.
For instance, if I want to create a led tube, I can either create a cylinder with an emissive material or choose a regular light and change its radius length so that it gets stretched into a capsule like-light.
Or let’s say I want to simulare an triangle art object that emits light into the scene. Should I make a triangle with an emissive material or should I put a regular light in it and force the light through a triangle pass-through frame?
Thanks for you insights
