Makes modifications to shader parameter values.

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

filter

The filter used to control which parts of the scene are processed. A Filter node should be connected here.

shader

The type of shader to modify. This is actually the name of an attribute which contains the shader network.

tweaks

The tweaks to be made to the parameters of the shader. Arbitrary numbers of user defined tweaks may be added as children of this plug via the user interface, or using the ShaderTweaks API via python.
