How to use object id textures in blender

Hello. I was just wondering how i use the Object ID textures in blender. I downloaded a fabric texture from andrew price’s website “Poliigon” and i noticed that there was a texture called Object ID and i dont find any information anywhere on how to use this type of texture… Can someone please help me?

Here is an example of ObjectID Texture


It’s a color image where each channel defines an area. RGB(A) channels, each a greyscale mask with values 0-1 range since it’s a .png.

R in this case defines the area between the circles, G defines the circles, Values 0 < R < 1 define a transition between the two, same for the green channel.

Since each channel is a greyscale mask, you can use it as a mix factor for whatever you like. Mixing colors, mixing two textures with different pattern directions.
