Hi,

I’ve stumbled across an error and I believe it might be a bug:  
If I add a material to a LinesMesh and apply a ClipPlane to my scene it will break the scene & not render anything.  
Example Playground: [Babylon.js Playground](https://playground.babylonjs.com/#S8K7T3)  
Commenting out line 15 will allow the scene to render again.

Welcome aboard!

Here’s the fix for this problem:

> <https://github.com/BabylonJS/Babylon.js/pull/11401>
>
> See https://forum.babylonjs.com/t/adding-material-to-linesmesh-results-in-bug-in…-clipplane/25063.
> 
> Note that \`ShaderMaterial\` now supports clip planes, so a bit of code can be removed from \`LinesMesh\`.

This PG will work once the fix is merged:
