renderLayer.camera

Set what a camera renders, as a layer-name filter.

renderLayer.camera("mainCamera", "all !shell")
renderLayer.camera("previewCamera", "all !ui !EditorUI")
renderLayer.camera({ component = { "Camera" } }, "all !debug")
renderLayer.camera("mainCamera")            -- no filter: read it back

A filter is a space-separated spec: a bare name includes that layer, !name excludes it, all includes everything. This is the same language capture takes.

renderLayer.set puts geometry on a layer; this chooses which layers a camera draws. The pair is what lets a wall occlude and bounce light in a bake while staying out of the shot.

An entity without a Camera component is an error naming renderLayer.set, since that is the tool for the other half.

Returns { id, name, renderLayers } per camera.
