Is there a way to have different textures on a basic cube?

Hi, I want a texture on one side of a cube meanwhile, I want another one on another side is this possible and how do you do this???

Probably not without writing some overly complex shader that can treat each face differently. But, what you’re describing is trivial is you use ProBuilder to make the cube. That will let you assign arbitrary materials to each face. You can still use a box collider for your object.

You can do that by making a texture atlas, that has different patterns and designs, for each face/side of the cube. And make sure to UV unwrap the cube in maya, or blender, or 3dsmax, import the cube into unity, import the texture atlas into unity, and then put the texture atlas onto the cube. And there is your multi patterned cube.

Or, in a pinch, just arrange six Quads into the shape of a box.

Yeah. Good idea.
But wait, wouldn’t that make it six seperate objects to process?

6

Yes. But that is likely not a problem.

Yeah, true.

I was able to do this with this shader I wrote

Shader “Custom/CubeSurfaceShader”
{
Properties {
_MainTex (“Texture”, 2D) = “white” {}
_Face1 (“Face 1”, 2D) = “black” {}
_Face2 (“Face 2”, 2D) = “black” {}
_Face3 (“Face 3”, 2D) = “white” {}
_Face4 (“Face 4”, 2D) = “white” {}
_Face5 (“Face 5”, 2D) = “white” {}
_Face6 (“Face 6”, 2D) = “white” {}
_BorderSizeF1 (“Border Size Face 1”, Range(0, 0.5)) = 0
_BorderSizeF2 (“Border Size Face 2”, Range(0, 0.5)) = 0
_BorderSizeF3 (“Border Size Face 3”, Range(0, 0.5)) = 0.03
_BorderSizeF4 (“Border Size Face 4”, Range(0, 0.5)) = 0
}
