culled Entity Ids
Any entity id's that should be culled when the block is considered culled by the BlockTextureEngine. The default implementation of onVisible and onCulled assumes that these are real entities When using real entities you cannot include entities in this list that are invisible by default, if you do they will not be culled properly.
You can include uuids of fake/packet entities, but you must override onVisible and onCulled If that is the case you may also be able to set isCulledAsync to true.
