Shaders and Graph

Shader Preview utility has full reflection information available including generation for: OSL, GLSL, MetalSL, Vulkan and MDL language targets, and uniform/path reflection as controlled by "complete" vs "reduced" generation.

Graph Editing utility uses a new connectivity and graph builder JS module and has support for generation of definitions from node graphs.

Python notebooks: A new connectivity book has been with accompanying support classes in mxtraversal.py for connectivity extractiom and Mermaid graph building logic now fully exposed and reusable. A shader reflection utility been added to the shader generation notebook. Definition creation and other notebooks have be updated to 1.39.

Utilities, Definitions

The property panel for definitions has been revamped to be more 3D editing and mobile friendly. See the design document for more information.
Graphic Design asset documentation is now available for the site.
The definitions reference is now in sync with 1.39 and includes a "Node Usage" notebook with code to determine the node usage in nodegraph implementations and which implementations use a given node.

Utilities

Start of new modular utilities using MaterialX Javascript modules: Core and ShaderGen. Latter is now exposed as a public module. Utilities including syntax hilighting, graph generation and code generation, and 3D viewer. Viewer requirements have been a driver for core updates.

Definition library comparisons are now available under the "Reference->Library Revisions" menu. This includes comparisons of the standard library from 1.38.0 to 1.38.9. The latest version denotes the start of a NPR library and the inclusion of the OpenPBR reference implementation.

Tutorials and Workflows

November 2023 - January, 2024

New additions have mostly been centered pipeline / Web development including glTF/JSON interop and glTF incorporation into the QuiltiX editoras well as additional OpenUSD support utilities. QuiltiX GLTF JSON USD

Start of interactive previews for references starting with glTF pbr. Reference Preview Rendering Improvements to glTF utility viewer support also added including drag and drop of glTF and environment files.

Working group information for a new procedural texture glTF (JSON) specification can be found for members of the Khronos glTF PBR working group.

Additional work to improve supported graphs, usability and performance of the ASWF MaterialX web viewer can be found here. (OpenPBR graph shown in viewer below) OpenPBR node graph (Note: Graphs used to create reference images are now previewable in the web viewer)
