I'm making wooden planks with the brick texture node and chose 2 grey colours. As far as I understand, it randomly picks a colour inbetween those two. My result contains a cluster of very similar boards, which doesn't look good. I tried making a new brick texture node and using the applying the same settings, but the result doesn't change. Is there a way to randomize the colours again?

  • $\begingroup$ I'm not sure you can with the node as is. You can try to add color-affecting nodes after the brick texture node, like a RGB Curves, to play with the end result, or use color ramps as color inputs. But to me it looks like the colors are generated by a form of noise but we have no seed option for that noise. What you can also do, is using your Mapping node to move the texture, maybe you will find a portion that better suits your needs. $\endgroup$

  • $\begingroup$ @L0Lock Thank you for the response. Found a portion via mapping node. $\endgroup$

It's a bit hacky but you can get new random values by feeding the output of the brick texture into a White Noise texture node.

You can either use a math node to add an offset to the noise to modify the randomness, or set the White noise input to "4D" and tweak the W input, but this is more computationally intensive.

Edit: sorry for the non-colorblind friendly colors.
