Alright, I don't know if this is the right place to ask this but I need some help.

I've been trying to port a Koikatsu model to vrchat using the guides above but they use an older version of blender.

I don't know much about texture editing but this is the best i could come up with (The textures are the highlights and such) How do I make the blender model look like the model on the left?

Can I do this on blender or do I need to create a shader in unity?! Please help
