Is there a built-in way to layer textures within the standard PBR shader?

Question

I want to have an effect similar to this question, in Aframe, to have layered swappable textures on a single model:

I am wondering if there is a standard process I h

You want to layer materials or textures using three.js.

Here is a pattern that is supported:

var geometry = new THREE.BoxBufferGeometry( 10, 10, 10 );
geometry.clearGroups();
geometry.addGroup( 0, Infinity, 0 );
geometry.addGroup( 0, Infinity, 1 );
geometry.addGroup( 0, Infinity, 2 );
geometry.addGroup( 0, Infinity, 3 );

var materials = [ material0, material1, material2, material3 ];

// mesh
mesh = new THREE.Mesh( geometry, materials );
scene.add( mesh );
