with BB 3 Beta 2 ready, I have many questions and requests: 1- API documentation (this can be auto generated, even if it is not final and changing, this should be top priority in my opinion). 2- from the Spawn node, I can spawn objects from assets, how to clone objects which can't be assets? like spawning light object. 3- we need more control over light object, like spot lights, choose which objects to cast shadows from that light? (probably through a node).
