Darker game on different PC devices.

Hello,

I've recently upgraded our project from strictly baked lighting to precomputed realtime GI. We've tested on different machines and they all looked consistent. However, after the switch, one of the machines we are testing on shows a darker overall lighting. This is from running an actual build with the same quality settings. Any ideas?

 

Do the shadows also look softer on the right image?

There are situations where Linear might fall back to Gamma (although I'm not sure why)

You can check QualitySettings.desiredColorSpace and QualitySettings.activeColorSpace see if something like that happens.

Also, a bug report from the affected machine might be nice (from the affected machine so they can get the details of that machine as well).

 

Thanks for your reply. The shadows look about the same for me, it's just that they are darker. They both look soft in both PC's. I did suspect it was the color space that was messing it up, however, wouldn't a fall back to gamma cause it to get much brighter and not darker?

I'll get more info on the machine that causes the problem.

 

No, typically Linear -> Gamma should result in darker colors. There are issues with Unity and Gamma though.

Actually, I'm not sure. But I think it's worth exploring.

 

Thanks for your input Acid. Followed up on the Gamma, but no dice. Here is a new screenshot of the issue:


Top left corner it says Linear.

 

:/ I have no clue. You should do a bug report.

 

Hmmm.. Thanks for your help!

 

UPDATE:

We've tried running the build on the problem PC in windowed mode as opposed to fullscreen - This solves the problem, so we're halfway through fixing this. Any ideas on why this happens would be appreciated!

 

i've found a similar occurence, unity 5.3.4p3, my dev machine runs the scene nicely in linear forward mode (no image effects, hdr off + msaa. gives a nice slightly saturated look), on my other machine, everything is very-very dark (fullscreen/windowed both), like it was rendered in gamma space, but even darker.

my dev machine has a GF920M, my other machine has a GF650GTX, same version drivers.

adding a (new cinematic) tonemapping image effect with hable+exp:2, seems like it almost fixes it, but the nice saturation is gone
(and the view on the two machines still look a bit different to me)

so still, any ideas on why this happens would be appreciated
