Hi there!
I am trying to make a Alpha cutout shader with a toon effect so that I can use it on character.
The compiler is giving me an error in unity in 2020.3.2f1 with URP
What should I do about my shader? Am I missing something? I would have used shader graph, except it wasn’t working with zwrite or something so the character kept showing up weird with the skin rendered in front of the clothes… a whole other issue that I couldn’t figure out. If you have any other recommendations, please let me know.
Thank you for your help in advance!
