Since "hint_color" and "hint_albedo" are both now "source_color" I changed those in the code and it looks like this (the black shades jitter a lot). Maybe I did something stupid, I'm a new GODOTer (I'm on Godot 4.1)
Hey, thanks for checking out the shader, and welcome to Godot! I have updated the asset with a Godot 4.x version. If you download the new file, it should work. Let me know if you need anything else!
It is possible, and it happened! I even double-checked that it was right. I'm getting used to using OperaGX I think I used the upload from clipboard button on accident. Oops!
