Yet another screen space global illumination (YASSGI)

Hello community! I am learning to write shaders and this is my first shader ever (so expect bugs) stitched together from various sources. It is yet another ssgi/raytrace/indirect lighting/yadayada shader, among many others like RadiantGI, MXAO, Glamarye's Fast Effect, and of course the big one -- dh_rtgi, which inspired me to write this and I owe it that blue noise texture. i've polished it to the point where my own gameplay with it is half-decent, not perfect because of course I am not that good, and decide to share it here.

(Will update in reply if things turned out well)

Some pics for comparison, taken in Garry's Mod (OFF/ON):




Notice:

1. I only tested my shader with Garry's Mod (DX9) and Skyrim (DX11), and mosty with gmod. Thus OpenGL and Vulkan are not garuanteed to work;
2. Still a bit visible light flickering/wobbling when moving;
3. Fireflies on minute faces and edges;
4. The global YASSGI_TECHNIQUE currently has no use. It is for a GTAO inspired bitmask GI algorithm I've yet to integrate. (It is already written in the file YASSGI_old_bitmask, just not merged with the main shader.)
5. The performance is quite varied. Indoors scenes see the most fps drop so stress test it in a room or something.
6. Non-sRGB color buffer are yet to be supported.
7. Actually, I find out that I didn't use that blue noise texture.

Critiques and suggestions are welcomed, as I am attempting to improve it further.

Thank you for making this! Please keep it updated!

In my experience, this is the second-best RTGI available for ReShade and the best RTGI for ReShade that is fully open source. This is a very(!) impressive result for such a new(!) RTGI!

I tried every single RTGI I could find, and this is my experience. Well done!!

The thing's been rewritten so expect difference from my previous screenshots.

The shaders folder includes a Skyrim version of the shader which is of no use now (even if you play Skyrim). It is safe to delete.

Hi, how I add "motion vector optical" shader?

I don't understand this sufficiently to interpret google results ...

Could you give an example of such shader? Do I have to load such shader before?after? Default setting will work? Thanks!
