feat (Stalker 2) (#80)
Browse files Browse the repository at this point in the history 
* Initial stalker 2

* Add more lutbuilders, final shader and tonemapper

* Initial working stalker 2 mod

* Add postprocess shaders, new luts, and correct gamma only in final shader

* feat(stalker2): remove unfinished lutbuilder, convert to srgb for postprocess shaders, bypass output shader adjustments

* feat(stalker2): Move colorgrading to final shader, disable custom code for vanilla

* feat(stalker2): Disable image corrections and use default SDR values instead

* fix(stalker2): Rework LUT sampling logic, restore mid gray value, and enable UI adjustments for all tonemappers

* cleanup(stalker2): Remove CS lutbuilders, adjust paperwhite default value

* regress(stalker2): revert lut sampling type to SRGB
