How to make a material paramater


Let’s say I have a tiling material for wood and metal. I want to create a new material that can just reference an existing material and use a mask to control where those materials appear. But I can’t find a way to make a material parameter (I just see parameters for textures and number values). It’d be great if someone could point me in the right direction in approaching this. Thanks! :smiley:


What you’re looking for is a Material Function. Here’s a tutorial showing you how to combine different materials, which I think is what you’re asking for:

Hi thanks for the reply! I forgot to mention that I was looking for a way to instance something like a layered material. Where I would be able to swap out the layered materials any time with other existing materials. But I can’t seem to make parameters out of the material functions that demonstrates.
