I'd like to make a character for my games, but I need tips how to make details. I tried burn tool, darken tool, lighten tools but it's going better. Also I don't know the details every brush function even I try it one by one.
on oldschool games like quake or half-life, they use fake shadow which is painted on texture or pattern to make details. I want to make something like that to make my character isn't looks like tiled. Did I need to use drawing pad?
First you can define your general sense of art style for your games. Did you wanna make it realistic? or cartoony? or somewhere in the middle? this need a deep understanding of how materials work the way they do and the creation of it.
A big helpful tip i can give you to give you a running start is to study texture maps. Maps like albedo/diffuse, normal, roughness and what not to give you an understanding of what you're doing. I can see that you just starting out learning but don't give up and keep practicing!
