self removing of sub elements component

[Tiska]

When the environment is removed, shouldn't we remove the sub elements from the scene ?

I try to remove the environment to set another sky in my scene, but i still have some content on my scene even after removing this sub elements (for example with the forest, i have a still have a green sky).

@Tiska you should remove the generated files from your PR.

Done ! Have you an idea about the sky color that stays after removing the component from the scene ?

I forgot about this PR. In my current project I'm doing

sceneEl.removeAttribute("environment");
sceneEl.querySelectorAll(".environment").forEach((e) => e.remove());

that is similar. Note in this PR, stars mesh, geometry, material are not properly disposed, only the entity is removed.
