LookdevX for Maya v1.3.0 Release Notes
LookdevX 1.3.0 introduces a variety of new features and a range of UX improvements.
Release Highlights
Support for both USD and MaterialX shading graphs
You can now use native USD and native MaterialX shading graphs simultaneously within the same Maya session. You can choose which data model to use from either the start screen of the LookdevX Graph Editor or when creating a new graph tab. You will also see a label in the node graph that displays the current data model.
MaterialX data structures
When you create a MaterialX material, Maya automatically creates the corresponding data structures, MaterialX Stack and MaterialX Document, which you can view in the Outliner. MaterialX Stack serves as a container for MaterialX Documents, which is where the materials are stored. You can create, import or export a MaterialX Stack or Document. You can also reference a MaterialX Stack.
Assign MaterialX materials directly to Maya geometry
You can now right-click to assign a MaterialX material to Maya geometry in both the Outliner and LookdevX Graph Editor.
Nodes identified with library names in the Tab menu
In the Graph Editor Tab menu, each node now displays the name of the library from which it is sourced. You can easily identify and select nodes based on their specific libraries.
Toolbar
This update introduces a new toolbar that provides easy access to frequently used actions, including Show/Clear selected materials, Collapse/Expand all nodes, and Clear Solo.
Usability updates: promoting/demoting attributes
You can now promote or demote an attribute to the input or output node with a simple right-click.
