Changed#

  • [CAD Converter] Updated to OpenUSD Exchange SDK 3.0.1.

  • [Converter Common] Exposed copy_output_assets() as a public utility and updated all converter dependency declarations.

  • [CAD Converter] Added HTTP 200 responses with conversion_status: 2, diagnostics, and INCOMPLETE history for usable incomplete DGN output.

  • [DGN Converter] Added structured results with clear success, failure, and incomplete status reports. Usable incomplete output can be imported.

  • [DGN Converter] Added diagnostics for parameter validation, file reading, geometry, and USD writing. Incomplete output messages direct you to the conversion logs.

  • [DGN Converter] Changed direct converter API calls to return Result objects. Existing unpacking and indexing remain supported.

  • [DGN Converter] Added material and file-texture conversion and optional source UV conversion with convertTextureCoordinates.

  • [DGN Converter] Added Deactivate and Hide level filters with eDeactivate and eHide.

  • [DGN Converter] Preserved model scale, placement, tessellation distances, and text transforms in files with mixed model units.

  • [HOOPS Converter] Added base-color, normal, emissive, roughness, metalness, and packed ORM texture export.

  • [HOOPS Converter] Added alpha-mask support for USD Preview Surface, OmniPBR, and OpenPBR materials.

  • [HOOPS Converter] Exported source images to a sibling Textures/ directory with relative asset paths and collision-safe filenames.

  • [HOOPS Converter] Added Preserve Source UVs with convertTextureCoordinates. The enabled default preserves source UV sets and seams.

  • [HOOPS Converter] Added prototypeAllParts to control whether all parts or only repeated parts become prototypes.

  • [HOOPS Converter] Added roughness and metallic controls to the default display-color material.

  • [JT Converter] Added external and embedded textures, additional UV sets, and per-texture UV selection for supported materials.

  • [JT Converter] Documented texture limitations and transparency behavior.

  • [JT Converter] Added roughness and metallic controls to the default display-color material.

Fixed#

  • [DGN Converter] Fixed a UI issue where the post-conversion pop-up dialog could be overwhelmed by character overflow after converting certain DGN files.

  • [DGN Converter] Preserved shared-cell colors, materials, and geometry references when instance materials differ.

  • [DGN Converter] Fixed Nucleus exports to include textures and referenced USD files, including usable incomplete DGN output.

  • [HOOPS Converter] Corrected meshes with mixed textured and untextured geometry, including triangle fans and strips with multiple UV sets.

  • [JT Converter] Fixed Nucleus exports to include textures and referenced USD files.
