I currently have a scene which uses a number of closeup layers (

, each layer is programmtically called, into an active state, theres is never more than one active layer in play.
Once I add the eighth layer- a close up layer become active on scene load. I have specifically de-activated that layer in the scene init script.
Having experimented by re-creating layers that does not address the probem, having also experimented by changing the order of the layers in the scene editor, that has had the consequence of stopping the scene from functioning at all.
I can see two potential causes,
1. There is a finite number of layers the engine can cope with in a scene
2. I have a corrupt scene file
