So to preface this, let me start by saying that I usually make all my maps for Gmod inside Counter-Strike Source for simplicity’s sake, because it has all of HL2’s assets as well as it’s own assets. I’ve noticed that the lighting doesn’t quite look the same when playing an identical map inside of Gmod. Most noticeably the point_spotlight entity acts extremely strange in Gmod, It flickers as I move around it and the halo effect at the source of the beam is missing. In the CSS version, the point_spotlights have the proper halo effect at the source of the beam, and they don’t flicker as I move around. Another thing I’ve noticed is that the lighting seems to be different on the map, even though it’s the exact same file, The lights seem overly-bright. In these two screenshots you can see the difference in the same map. One is loaded in CSS and the other is loaded in Gmod
This is the CSS version, note the halos around the streetlight and on the car’s headlights
This is the same map inside of Garry’s Mod, The light halos and glow are missing, and the spotlight looks a lot crappier in general. What you can’t see in this screenshot is the point_spotlight flickers noticably when you walk around it, and there’s a strange white flicker if you stand in the path of the cop car’s rotating lights
Has anyone else ever encountered this? I tried googling for stuff like “lighting looks worse in Garry’s mod” or “point_spotlight broken in Garry’s mod” and couldn’t find anything. I also tried playing with my video settings to see if that was causing it. I tried turning HDR on and off and bloom on and off and it didn’t seem to affect it. If anyone has a solution please let me know.
