RenderPassShader
Sets up a global shader in the options to replace a shader used by a render pass type.
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
out
The processed output scene.
enabled
The on/off state of the node. When it is off, the node outputs the input scene unchanged.
in
The input scene
shader
The shader to be assigned. This will be stored as an option within the scene globals.
renderer
The renderer the shader should affect. Shaders assigned to a specific renderer will take precedence over shaders assigned to “All” when rendering with that renderer.
usage
How the shader is to be used.
