The Render Pipeline allows you to use Rendering Layers, which are LayerMasks to make Lights or effects only affect specific Renderers.
Rendering Layers are also supported on decal projectors, and can be sampled from the ShaderGraph to implement custom effects.
Rendering Layers are a Bitmask and it represents the 32 Layers and define them as true or false. Each bitmask describes whether the RenderingLayer is used. As an example, bit 5 can be set to 1 (true).
Edit->Settings->Tags and Layers option shows the use of the 32 bitmasks. Each RenderingLayer is shown with a string setting. As an example Layer 0 is set as Default. There is always at least one defined RenderingLayer.
| defaultRenderingLayerMask | Returns an instance of Default Rendering Layer Mask. |
| value | Converts a layer mask value to an integer value. |
| GetDefinedRenderingLayerCount | Returns a number of Rendering Layers defined in the Tags and Layers manager. |
| GetDefinedRenderingLayerNames | Returns a names of the defined Rendering Layers in the Tags and Layers manager. |
| GetDefinedRenderingLayersCombinedMaskValue | Returns value that represents all defined Rendering Layers in the Tags and Layers manager. |
| GetDefinedRenderingLayerValues | Returns a values of the defined Rendering Layers in the Tags and Layers manager. |
| GetLastDefinedRenderingLayerIndex | Returns an index of the last defined Rendering Layer in the Tags and Layers manager. |
| GetMask | Given a set of rendering layer names as defined in the Tags and Layers manager, returns the equivalent rendering layer mask for all of them. |
| GetRenderingLayerCount | Returns a number of Rendering Layers defined in the Tags and Layers manager including empty ones. |
| NameToRenderingLayer | Given a rendering layer name, returns the rendering layer index as defined in the Tags and Layers manager. |
| RenderingLayerToName | Given a rendering layer index, returns the name of the layer as defined in the Tags and Layers manager. |
| RenderingLayerMask | Implicitly converts uint to a RenderingLayerMask. |
