This mod aims to bring highly realistic (human) g effects to KSA, including blackout, redout, ALoC, GLoC, death through G forces and confusion/disorientation.

While I'll try to get it realistic there aren't many sources for a lot of the things and I don't have any personal experience but I'll gladly accept any help in getting it more realistic.

Unlike the KSP G-Effects (Reaffected) mod the visuals are intended to be fully shader based.
It doesn't seem to be possible yet to use custom shaders but if that changes or is incorrect I would highly appreciate help in getting that working.

G forces through rotation are planned but I can't tell yet how well it'll work.

Current state:
Gz+ response curves are available in the logic repo.

In progress:
Basic KSA integration

Sources and licenses:

Yeah don't think custom post process shaders are possible yet, not sure when they will be either as the BRUTAL framework has a long way to go. I have a lot of experience in this area though, so once it is possible I'm happy to contribute!

Currently working on getting a simple greyscale shader correctly working, there are still some internal issues.

Got a single hardcoded shader working properly (I'll only use a single shader) but for getting this integrated into KittenExtensions I need a bit more work to add multi shader and priority support.

A short update after a long time:

The post processing shaders are now an independent mod (ShaderExtensions) and the KSA G Effects mod has a GitHub repo now though not much is there yet, mostly test stuff for the ShaderExtensions mod. It is licensed under GPLv3

The G Effects Logic is now a separate project with it's own repo. It is also licensed under GPLv3 but with a for contributions mandatory CLA which mainly grants me the necessary rights to sell and sublicense this project without prior notice.

The Gz+ response curves look okay for now so I will work on the KSA implementation and some basic visual effects,

Ignore the green line, that was just left from a failed test.
