Set Nodes to Shader





   






Shader Presets


'Set Nodes to Shader' is part of the Shader Preset system available in the Shaders Palette.


Set Nodes to Shader is part of the Shader Preset system and allows you to quickly preview your node selection with a shader, making

it act like a 'isolate select' for materials.


It works by scanning the selected Node Names for matching parts against Channel Names that have been previously saved as Shader Inputs

via the Save Shader Preset Tool in the Shaders Palette

Usage Example


Saving a Preset


In the below example we have a VrayMtl Shader.

We have assigned Channels to the different Shader Inputs via the Shader Palette using the Dropdowns.

On the right you can see the same shader setup represented in the Nodegraph

In order for the Shader to know our Name preferences for the future (Diffuse Color = DIF, Bump Map = BUP etc.)

we save a Shader Preset by right clicking / Save Shader Preset.


Whenever we create a shader with the Name VrayMtl in any project Mari will now start looking for existing Channels that

match our previously used Naming Convention.

Isolating a Material in the Nodegraph using 'Set Nodes to Shader'


Below you can see an example of a node selection. The Nodes are currently not connected to a shader.


Notice that - while the Nodes have different Names than the Channels we have saved as part of the Shader Preset, they contain the same

identifiers such as Metal_DIF, Metal_BUP etc.


With the Nodes selected and the Target Shader Selected in the Shader Palette, once we run Set Nodes to Shader, all Shader

connections will be made automatically. Any shader connections that can't be made (because no Node with the appropriate Name was selected

will be cleared.


Run Set Nodes to Shader again without a Node Selection (but with the Target Shader selected in the Shader Palette) and the previous state will be restored.
