Picking groups or filtering #22221
Description
What problem does this solve or what need does it fill?
I have some overlapping picking meshes, which form 2 separate sets for selection. One set is active at a time, depending on the application state. Think "select an object" vs. "select a part of an object". I don't see currently a way to handle that; picking selection just flickers between one or the other since they're both active (all meshes are picked). Note I already use Pickable, because most mesh are for rendering and not picking.
What solution would you like?
Disjoint sets of picking, like groups. Allow enabling and disabling picking on some meshes without having to spawn/despawn components.
What alternative(s) have you considered?
Spawn/despawn components or entities. This is a lot more work and manual bookkeeping.
Additional context
I believe some of the third-party crates used to have that. Can't remember on top of my head which one.
