Asset texture is divided into 4 different textures

Hi,

First of all Im new to Unity, just started my game development course this week, so apologies if you don't understand what im trying to say or if this is in the wrong forum.

I downloaded a free asset ('Grass road race'), and the texture of the grass comes with 3 other different textures, all in the same file. It is divided into 4, how do I select a specific texture from the 4?

I've added a screenshot so you can see what I mean.

Thanks

 

I guess you have to use a prefab that comes with it, which probably contains a mesh that is unwrapped to use that packed texture.
Alternatively you can split it in Photoshop/Gimp etc.. or create and unwrap your mesh to use the packed texture yourself.
