# useFullLayers

> Controls if full 64-bit layers are used based upon PhysicsLowLevelSettings2D.physicsLayerNames or if not, the standard 32-bit layers based upon LayerMask. If a PhysicsLowLevelSettings2D asset is assigned then the full layers ( PhysicsLowLevelSettings2D.physicsLayerNames ) will be used if PhysicsLowLevelSettings2D.useFullLayers is also active. If no PhysicsLowLevelSettings2D asset is assigned then the global layers (See LayerMask ) will be used.
