Use this for your alpha channel on the lerp node, on your sample texture and also have texcord on it to tile it like you want. Node A and B use the same texture but with different tiling output, or two different textures, don’t forget to add texcoords to them also, just play with the texcoords to see how it changes.
Here I used two different textures with the most basic setup.
Texcoords on them are 10 by 10 each for each texture and on the alpha I use a texcoords of 3 by 3.
and the effect on a cube, this is the material on a cube.
This is just simple channeling, as you can see with just a simple form the tiling is almost gone, it’s almost non present, I did not use micro or macro variations on it.
There is complex channeling once you get the hang of it, you can do all sort of crazy stuff. After you optimize your textures use variations and channel it a few times there won’t be any tiling effect.
