Added#

  • Expanded the Material Graph user and developer documentation with current UI screenshots, task-focused guides, preferences, validation behavior, troubleshooting, and corrected API examples.

Fixed#

Added#

  • Added MaterialX upgrade functionality.

Fixed#

Fixed#

  • Startup screen now shows up when currently edited material is deleted from the stage.

  • Empty NodeGraphs keep the grid background and breadcrumbs visible after all nodes are deleted.

  • MDL polymorphic constructor catalog entries now collapse single-input overloads under result type names, while preserving explicit names for multi-input constructors.

  • MDL polymorphic candidate tooltips now show the correct MDL type names for user-defined struct types such as ::base::texture_return.

  • MDL polymorphic connection validation now rejects incompatible struct connections while allowing valid texture_return inputs.

  • MDL polymorphic input resolution now permits int sources to resolve to float overloads when no exact int overload exists, while still preferring exact overload matches.

  • Schema-driven port group labels no longer accumulate repeated anchor prefixes after node sync, move, or page expansion.
