A RenderPass can be split into several Layers, each can render a different set of objects. During rendering of the RenderPass, all Layers are rendered at the same time.
Setting which objects to render in a Layer
In the RenderGraph, connect a flow to the visible input of a Layer node. In the Render Layer attribute, dial in the name of the Layer to render into.
Rendering objects as Matte (or Holdouts, Back holes)
In the RenderGraph, connect a flow to the matte input of a Layer node. Set the Render Layer attribute to the Layer to render matte into.
Disabling a Layer rendering
You can disable the rendering of a whole Layer by either:
- Checking the Disabled attribute of its properties
- Switching the first checkbox in the Passes view, on the row corresponding to the Layer
Rendering only a set of Layers
Alternatively, you can also 'solo' one or several Layers by click the 'S' button in the Passes view.
Duplicating a Layer in a RenderPass
To duplicate a Layer, simply click the '+' button at the far right in the Passes view.
