I’m working on a sports game inside a stadium.
What is the usual way to go about creating a short cut lawn like this:

I worked out three possibilities so far:
-
Painting with the built-in Terrain. I couldn’t get this to look good. If this is suitable how to achieve a reasonable look?
-
Using a material with normal, ambient occlusion and displacement maps. I did not find any texture packs with said maps aside from normals. [Sadly, Blender which I use for modelling can’t bake those maps using it’s particle system which is used for grass because the particles are no meshes.]
-
Shader shenanigans. I have no idea how to do that as I’m no pro in coding shaders. Pointing me into the right direction would help a great deal.
Any help is greatly appreciated as my grass looks really flat with a simple texture.
