Hi everyone,  
Am trying to create a layered material with PBR material as base and procedural noise (hopefully allows some color control of noise) on top of it, I found this [Noise material in babylonjs - #8 by Mostafa\_Salloum](https://forum.babylonjs.com/t/noise-material-in-babylonjs/40506/8) but this only talks about the perlin noise, How can one combine this with a PBR base?  
Thank you.

Hello!

You could use a PBR block if you use Node Material:

Or you could use a MaterialPlugin: [Material Plugins | Babylon.js Documentation (babylonjs.com)](https://doc.babylonjs.com/features/featuresDeepDive/materials/using/materialPlugins)
