How do I retexture game files like sand in photoshop?
I know how to create textures, but I suck, and will hopefully get better at it. But how am I supposed to do this?
I'm a bit late, but these are called "Normal Maps" I think.
YOu can create them using this webstie for example : http://cpetry.github.io/NormalMap-Online/
Just drop you image in there and it'll create the normal for you, and there are some options too.
@bur587 The Nvidia Texture Tools for Photoshop will create them as well.
