I am creating my first landscape in unreal engine 5. I want to create a landscape similar to genshin impact, and I created a nice landscape with the sculpting tool. However, I am struggling with textures. I know I need a material with ambient occlusion, normal and roughness, but I don’t know how I can actually make them. All the assets I have found online (free only) are either realistic looking textures or a simple rgb color. So my question is what tools are there to make complex textures with all the stuff I need. Preferably free.
thanks in advance
