Hi,

Still getting my head around Babylon and JS, so I apologise in advance if this is a daft mistake.

I’m having a few issues with getting the GUI, layermasks and interactions all working together.

I’ve built out a model of data centre with a 3D and 2D Gui. Before I set up layermasks, I could click on the coloured cables to launch the GUI. I added the GUI to layermasks to render after post processes, but now I can’t click on meshes any more?

Any help would be massively appreciated!

Hello and welcome to the Babylon community! Your project is looking very cool already 😃

You actually don’t need layer masks to have the GUI not be affected by the post processes, there’s an attribute on the Layer class (`layer.applyPostProcess`) that can enable it to not be affected: [PGDemo | Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#N96NXC#125)

Thank you so much for your help, massively appreciated! I’ve been banging me head against a wall for the past couple of days!
