Added

  • Added support for the fract node, with implementations in GLSL, OSL, and MDL.
  • Added a bitangent input to the bump node, aligning its feature set with the normalmap node.
  • Added support for OSL 1.14 in shader generation, leveraging the latest closures when available.
  • Added support for MDL 1.10 in shader generation, leveraging the latest closures when available.
  • Added initial support for data library builds, allowing future releases to generate derived artifacts from the MaterialX data libraries.
  • Added an ElementVec type alias in MaterialX C++, allowing certain patterns to be expressed more clearly and concisely.

Changed

  • Improved the compatibility of MaterialX shader generation with Hydra Storm.
  • Refactored the type system in shader generation, improving the thread-safety and robustness of the generation process.
  • Improved the implementations of the BSDF operator nodes, preferring data definitions over explicit C++ code.
  • Improved the implementations of the time node, using a graph definition in hardware shading languages.
  • Optimized GitHub CI to reduce build times for contributors.
  • Raised the minimum CMake version to CMake 3.26.

Fixed

  • Fixed two edge cases in the version upgrade logic for normalmap nodes, addressing the usage of MaterialX versioning in OpenUSD.
  • Fixed tangent frame orthogonalization for the normalmap node in OSL shader generation.
  • Added validation of tree depth and XInclude depth in XML parsing, addressing cases where unusually complex documents could trigger a stack overflow.
  • Adding two missing null checks in the getShaderNodes helper function.
  • Integrated fixes to OSL type classes from recent work in the OSL project.
  • Improved the handling of invalid materials in the MaterialX Viewer, addressing cases where missing lights could trigger a crash.
