I'm a bit confused too. I thought that Vue handled most of this stuff more efficiently than other apps by storing ans manipulating many items as software proceedures, instead of as geometrical objects. But if you bake most items into meshes (their "physical" version, as opposed to their "virtual" version), aren't you requiring Vue to work harder, use larger storage and use more memory? I notice that when i bake objects to meshes for export purposes, scenes seem to get slower.
