Archviz with Spot Lights Only
From most of the videos I've watched or articles I've read about archviz in UE4, most of them involve some sort of skylight and directional light. I'm working on a visualization of a theatre room which has no windows or any way for exterior lights to penetrate. I'm only lighting the scene with spot lights. Are there some special considerations or variable parameters for this lighting scenario that I should take into account?
I'm also getting a weird banding issue on walls when static spot lights are pointing on it. They go away with stationary lights, but the 4 stationary lights restriction (unless you turn off shadows) makes it difficult to light a whole room with only 4 stationary lights. I'm also still getting some other artifacting with static lights (banding, black splotches, jaggy shadows) even with the settings below.
