thanks for your answer.
I tryed it but it didn't worked yet. You have to provide a 'layerId' and a 'LayerName'. But I don't know how to get the LayerId.. I just tried with 0, but nothing.
Also I found a function in EntitySystem
// Enable entity layer
virtual void EnableLayer(const char* layer, bool isEnable, bool isSerialized = true) = 0;
But it doesn't work.
Maybe someone get this working ?
