Hi All,

I’m trying got use the default render pipeline on my scene, the effects are working exactly as desired on my meshes. However, they’re also being applied to my UI elements, which I do not want.

I’ve reproduced the issue in this playground: [https://playground.babylonjs.com/#ZI9AK7#1534](https://playground.babylonjs.com/#ZI9AK7#1534)

In the Playground that demos the options int he render pipeline, the UI is not affected: [https://playground.babylonjs.com/#Y3C0HQ#146](https://playground.babylonjs.com/#Y3C0HQ#146)

I can only think this has something to do with the difference between `CreateFullscreenUI()` and `CreateForMesh`? Is there anyway of disabling the rendering pipeline effects for the `CreateForMesh` UI?

Thanks in advance,

Joe

Unfortunately no as the mesh UI is a texture inside the scene (which is affected by the rendering pipeline) ☹

Is there no way of rendering two cameras at the same time, or something like that? With the effect on being applied to the first camera?

I understand that’s how [Unity’s Camera Stacking](https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@7.2/manual/camera-stacking.html) works?

I’ve managed to add world-space UI elements into the scene, that are then not affected by the DefaultRenderPipeline, however, the `linkWithMesh` doesn’t seem to work when applying the `layerMask`:

Got It!!!

Turns out the `layerMask` was working perfectly, however the `FreeCamera` was not moving, so the perspective to the UI element was always the same, which gave the illusion of the `linkWithMesh` not working.

The trick to get this to work was to then make the `SecondCamera` identical to the first camera. Then add an `onViewMatricChangedObservable()` on the first camera. When it’s view updates, copy the parameters over to the second camera too.
