Huge lighting discrepancy between scalability settings

Hi!

I have a room with around 20 static lights that I used to generate baked lighting. Then there is also a single stationary light to cast dynamic shadows.

However, if I put the Post-Processing scalability setting to low of medium, the whole room becomes very dim. At High/Epic, the light is bright. I can’t find which post-processing setting affects this by turning them on/off in the GlobalPostProcessVolume.

Any idea what I might need to adjust?

Can you post a screenshot of the difference you are seeing please?

Also the scalability setting is overriding the post process settings you have so figuring out which option makes the difference wont help you i think. What you can do is leave the post process quality at Epic and then lower or disable expensive post process effects like AO, depth of field, motion blur, etc. manually in your global pp volume.

Here they are. Yeah, that’s what I was doing, leaving the scalability setting to high then playing with PP settings to try to get it to look dim…

I’ve just noticed that even just the sky dome looks way different, bright and dim. I don’t think that has anything to do with the inside lights. I’ll create a new scene to check.

Found the issue. For some reason the Auto Exposure Max Brightness was set very low (0.03), same as the minimum value. Set it back to 2.0. Now the scene is dimmer in general.

I’m not sure I understand why Max Brightness set higher leads to a dimmer scene. Still investigating these settings.
