Unity version : 6000.0+
Tested with : Win DX11 \
Most shader in this repo works for Built-in RP, and it will also work in older unity versions as Built-in RP didn't change for years.
Some of these Built-in RP shaders will also work for URP but note that they are not SRP batcher compatible. Need some small work to convert them properly.
Shaders named with URP/HDRP will only work for URP/HDRP.
Disclaimer: The stuff here are not optimized. Just for fun.
