Hey! Sorry for the late reply.
Since it overlapped with both, I merged it with my two shader mods. Everything seems to work, but I'm not sure it or the original includes BrightCaSFix.
The code for making Sims and objects brighter is there, but its values are set to the game's default. The BrighterSims readme explains how to edit those.
