I Like To Work On Texture :: Unity Ver 2017.3.1

I been using Unity Ver 2017.3.1 and will like to try out Terrain Texture.
Hurt all over the shop but cannot try out.
Anyway to test out?

Test out what exactly? Do you want to put a texture on a terrain? You can just add an image to unity as a texture, and then paint it on the terrain: https://docs.unity3d.com/Manual/terrain-Textures.html
