### Install Vulkan SDK and \*ensure `spirv-cross` and `glslc` are in PATH\*.
1. Enable `dumpShaders` in config.toml
2. Run `spirv-cross -V fs_0x000000.spv --output fs_0x000000.glsl` to decompile the SPIR-V IR to GLSL.
3. Edit the GLSL file as you wish
4. To compile back to SPIR-V, run (change the _**-fshader-stage**_ to correct stage):
`glslc --target-env=vulkan1.3 --target-spv=spv1.6 -fshader-stage=frag fs_0x000000.glsl -o fs_0x000000.spv`
5. Put the updated .spv file to `shader/patch` folder with the same name as the original shader
6. Enable `patchShaders` in config.toml
