The scale of my scene should be fairly correct, as I’m importing a sketchup model with realistic dimentions, and it all lines up to the default FPS character. Walls are generally around 100mm thick. the floor is about 300mm thick.
I have maybe 60 lights in the scene, with about half of them in view at any one time (attenuation radius set to about 300 on all of them). I’m attempting to replicate the lighting that real down-lights would produce, so I “need” one spotlight per down-light. How many is a “lot”? I’m happy with degraded performance when all the lights are on, because all I want to do is render out a sequence, it’s just the artefacts that are an issue.
I had a look in all the visualise modes but nothing stood out to me.
