I added an Image Texture to a plane using a seamless image. In the Texture context of Properties window, I set Scale to be X:10, Y:10.

Unsurprisingly, a pattern forms when you zoom out from plane:

How can I get rid of this pattern? (this is supposed to be grass, so it should look very random)

EDIT: For example, is there any way to add distortion to how the image is tiled onto the plane? So if I were to represent the surface of the plane with a grid, the pattern on it would become distorted, like this

You could try something like this:

With undistorted coordinates:

With distorted coordinates:

And with a checkered texture:

One solution i found was to add a copy of the same image, make it about 2.5 times larger, and rotate it my about 30 degrees. then use a mixRGB node to mix the 2, and set the factor to a noise texture, which is running through a brightness contrast node...

enter image description here

i actually keep this saved in my startup file as a nodegroup xD

  • $\begingroup$ Cool, that definitely helped although there were still some patterns left when you zoom out far enough because it's still only made of two repeating patterns (combined in a noisy way). I suppose you could also add a third or fourth of the same texture with slightly different rotations and scalings. $\endgroup$ – Garrett Apr 4 '14 at 9:35

    $\begingroup$ @Garrett indeed... either way with textures you will eventually see pattern-ing. I advise that everyone learn how to create procedural textures. Although i will say that the idea you had (gandalf's answer) really intrigues me ... $\endgroup$ – Konner Rasmussen Apr 4 '14 at 23:41

You could use your brush as a texture in texture painting mode: http://wiki.blender.org/index.php/Doc:2.6/Manual/Textures/Painting#Texture
