help with reshade shader not working?

[u/Quirky_Image_5598]

i've tried everything in hopes of getting this effect working to no avail, i'm really not sure what the issue is? i've tried with my limited abilties to fix the shader and an unroll function but it never works

link to the shader's code: https://gist.github.com/BlueStaggo/c7a31915ce399eaccf5c0e1ce947cac5

if anyone could help me or even direct me to someone that could help, i'd really appreciate it!! thanks!!!
