, how does lightmap resolution work differently in GPU Lightmass versus the old CPU version? I’ve noticed that doubling it does not make my render time 2x2=4 times as long; I also thought that you said that surfaces reflect more light if they have a higher resolution. Would you be able to briefly describe, I’ve been experimenting and am not totally sure what I’m seeing at different resolutions. The speed of GPU makes it easier to test, though.
