Controls layers drawn in a frame graph branch. More...

A LayerFilter can be used to instruct the renderer as to which layer(s) to draw in that branch of the frame graph. The LayerFilter selects which entities to draw based on the Layer instances added to the LayerFilter and as components to the Entity.
The LayerFilter can be configured to select or discard entities with a specific Layer depending on the filterMode property. By default, entities referencing one of the Layer objects that are also being referenced by the LayerFilter are selected (AcceptAnyMatchingLayers).
Within the FrameGraph tree, multiple LayerFilter nodes can be nested within a branch going from root to a leaf. In that case the filtering will first operate on all entities of the scene using the filtering method specified by the first declared LayerFilter. Then the filtered subset of entities will be filtered again based on the filtering method set on the second LayerFilter declared. This is then repeated until all LayerFilter nodes of the branch have been consumed.
