Hi!
I can get an object level object to act as light easily.
But how can I make say box that has top polygon as light and otherwise normal material?
I managed to make it emissive by using Diffuse material with Black body connected to emission input but the light power is very low, hardly notable.
It seems that I can only get real light from an object by using the object's Light emission tab but then the whole object acts as light so emissive materials would be useless. So I must be doing something wrong
Can somebody please give simple example (I'm new with Houdini too) how to make that box with top polygon as real light?
Please help me, thank you very much!
