Blend materials/substances?
I have some big areas so when I apply a substance it has a obvious repeating pattern.
I would like to merge two substances using a mask that I can tile and rotate independently to add some variation in a similar way the Terrain Toolkit does. Is there a simple way to do this? A special shader maybe? Any push to the right direction?
you have to write or find a custom shader script. I wrote one for my game cause i couldn't find one.
Actually here is what i wrote for my game. it blends three textures on a surface. you have to make a map texture in paint. Use black red and blue color on the map to assign where the textures go. hopefully it helps
Shader "todds/3Textures" {
Properties {
// _Color ("Overall Color", Color) = (1,0.5,0.5,1)
_t1 ("texture in white", 2D) = "white" {}
_tint1 ("Tint1", Color) = (1.0, 0.6, 0.6, 1.0)
_t2 ("texture in red", 2D) = "white" {}
_tint2 ("Tint2", Color) = (1.0, 0.6, 0.6, 1.0)
_rc ("low cutoff", Range(1,80)) = 0.0
_t3 ("texture in blue", 2D) = "white" {}
_tint3 ("Tint3", Color) = (1.0, 0.6, 0.6, 1.0)
_rb ("low cutoff", Range(1,80)) = 0.0
_t4 ("texture map", 2D) = "white" {}
}

//Tags { "RenderType"="Opaque" }
