A node that controls how the object faces the camera to be used within the visual shader graph. The output port of this node needs to be connected to [code]Model View Matrix[/code] port of [VisualShaderNodeOutput]. Controls how the object faces the camera. See [enum BillboardType]. If [code]true[/code], the shader will keep the scale set for the mesh. Otherwise, the scale is lost when billboarding. Billboarding is disabled and the node does nothing. A standard billboarding algorithm is enabled. A billboarding algorithm to rotate around Y-axis is enabled. A billboarding algorithm designed to use on particles is enabled. Represents the size of the [enum BillboardType] enum.
