Grass texture: https://opengameart.org/content/10-se... Noise textures give programmers a way to introduce random and organic elements into their effects. In this video I'll show you how you can use noise textures in a shader to create a simple texture blending effect. There are so many ways that you can use noise to create awesome looking visuals, so hopefully you find this video useful and pick up a few tricks!
