Gamma correction is screwed up somewhere, this is what it looks like to me.

@CasualDev242
can you try these settings in console?

cfg_load grading_default
r2_gloss_factor 0.001
r2_gloss_min 0.35
r2_sun_lumscale 3.0
r2_sun_lumscale_amb 1.0
r2_sun_lumscale_hemi 1.1

That fixed it. You didn't include the different color grading config files in your commit, unless I copied it wrong, so I downloaded Enhanced shaders and loaded the cfg grading_default that way. If the screenshot looks too bright it's simply because I overdid it with the Indirect Lighting for testing.

Due to size, this branch will no longer receive any more updates. Any additional updates for this functionality (e.g. UI for new options, script functions ported to engine, etc) will be in separate PRs.

As of now, the support for using new shaders is in place, so I consider this feature complete.

Tried to test locally. In general game looks better with new shaders, especially water. Not sure if I have done everything wrong, but here are some observations regarding pr/game:

• It has ~140mb of textures. It makes sense to enable lfs for the repository or move all game assets into separate submodule with lfs enabled. Gitlab is more generous in terms of free mbytes for data storage
• Seems like different grading support will be part of another PR, but when I tried to cfg_load other presets than default validation failed for vector4 numeric ranges
• Probably it will be easier to add original bind script as separate PR and then changes will be easier to review. As I understand, it is just few lines to run game start callback
• I believe it is rather specific to me, but raindrops were rather like dark ink and had near blue color with new shader
• When I turn on SSAO mode HBAO everything is screwed up for me

Actually, not superseded: to make SSS-18 commits easier to diff
