I’m aware emissive surfaces should not replace analytical lightsources, I mention this only in case this behavior is unintended; Emissive surfaces seem to completely stop emitting light in the LumenScene/SurfaceCache when scaled below a certain size:
Seems like theres some non-uniformity to it, for example making a 95x95cm plane won’t emit light into the surface cache, but a 50x126cm plane will work just fine.
Also, what is the difference between the “Lumen Scene” and the “Surface Cache” view in the visualizer? Just the additional debug colors in the Surface Cache view? They seem identical otherwise.
I’m really looking for the 5.0 release (and the future of Lumen beyond that), you guys have done an incredible job all around.
