OS: Windows 10 x64  
Browser: ungoogled-chromium 108.0.5359.95

Open the inspector and expend the materials.

Expected:  
The colorShader and colorShaderOccQuery should be excluded from serialization and not being loaded again.  
Referring to [BABYLON.ShaderMaterial#doNotSerialize](https://doc.babylonjs.com/typedoc/classes/BABYLON.ShaderMaterial#doNotSerialize)

Actual:  
The colorShader and colorShaderOccQuery is serialized and loaded, and never reused again.

The two shaders used by the bounding box renderer are not flagged as `doNotSerialize`. If you don’t want to serialize them, you can set `doNotSerialize=true`:

[EDIT] You’re right, though, that we should not serialize them in the first place, so here’s the PR:

> We should not serialize those materials as they will be recreated automatically when needed.
