This is a VHS shader with scanlines, deformation and a Fully Working Fisheye, It use the classic shadows and lighting ou minecraft, so the performance should be good, (Tell me in comments if there is bugs or something not working) I recommend using this shader with my mod
- VHS Backrooms : Found footage
This is shader works with
-Iris
-Oculus
-Optifine maybe not works beacause i not tested the shader on it
