When using a clipPlane on a mesh, the outline effect is not taken into account.
I’ve guessed it is a mesh (maybe I’m wrong?), but if so, it’s not visible in scene.meshes.
So, is there a way to access to the outlines elements?
The outline renderer does not currently support clip planes. Here’s a PR for that:
You will get:
(not totally sure it’s what you expect)
Note that the outline is not a separate mesh, it’s the same mesh which is rendered with its vertices moved along the normals to make it a little bigger.

So technically, the outline is “just” a shader. Nice, thanks for the PR!
It is a special shader that is used to render the mesh a first time, which will render the mesh a little bigger and with the outline color. Then the mesh is rendered over it with its regular material.
