‘Noise’ in 3D refers to a way of gen­er­at­ing val­ues us­ing a math­e­mat­i­cal al­go­rithm. Rather than us­ing, let’s say, a tex­ture map along with UVS to ap­ply val­ues across the sur­face of the mesh, noise can gen­er­ate th­ese val­ues and as­sign them to an at­tribute. Nor­mally, you might use noise to help in tex­tur­ing some­thing… but in this case, we can as­sign this value to some­thing be­sides the colour – aka the cus­tom at­tribute that con­trols the black mar­ble vs gold – and that’s how we can make it all work!
