Apologies if i’m wrong about this.
If i have items in my scene assigned to a layer and then i decide to move them to a new layer/ another layer, i have to remove them from the old layer they already belong. This seems like an incorrect behavior. I would assume once i’ve assigned the items to another layer they’re ONLY going to belong to that layer. If i’m wrong about this, please let me know. i’d love to have this changed, never seen a 3d program let me assign assets to multiple layers, it just makes things confusing.
