Recommended Asset

The A+ Grass asset contains a few textures/sprites to get started with. If you want a bigger set of textures, consider checking out the Foliage Sprites pack by Kenney.

I do not own the Foliage Sprites pack, and have not been involved in its creation. I am simply recommending it, as it is an amazing free foliage pack which works perfectly with the A+ Grass shader.
