Yeah, that’s true; I wasn’t expecting the sky atmosphere to get brighter as the skylight is a separate actor, and we are correct, it doesn’t. So I’m surprised that it appears to get exponentially brighter in the reflection when I turn up the skylight. I figured the reflected world would know to exclude the skylight’s effect on the sky atmosphere just like the non-reflected world does. It just doesn’t seem…correct. Like, the reflection is fully accurate except for that.
Raytrace GI doesn’t actually seem to be affecting my scene all that much, if at all. Here’s my settings on the PP and the cvar r.RayTracing.GlobalIllumination 1:
cvar r.RayTracing.GlobalIllumination 0 (off)
It’s a very slight change toward the top end of the map, closer to the sky. None of the PP settings increase its effect. Perhaps I’m missing something? I’d like to try increasing the effect of raytrace GI.
Regular GI uses indirect lighting which is lightmass, right? My lights are dynamic/stationary so I understand that means I’m not using regular GI.
Anyway that slight change I’m getting isn’t worth the incredible drop in framerate that raytrace GI causes. If I could increase its effect perhaps I could try optimizing it.
If I can’t get the GI to help out then I guess I’ll need to litter my map with non-shadow casting fill lights and yeah, more actual lighting like the lamps?
