Changed#

  • [CAD Converter] Legacy conversion parameters backward compatibility

  • [DGN Converter] Updated to ODA Kernel and Drawings SDKs 27.2

  • [DGN Converter] Added ConversionStyle enum - eNone (0): Skips elements conversion. - eAttributes (1): Converts elements to USD attributes only. - eRenderable (2): Converts elements to both renderable geometry and USD attributes. - Added meshConversionStyle parameter to control the conversion style for mesh elements using the ConversionStyle enum. - Added curveConversionStyle parameter to control the conversion style for non-text curve elements using the ConversionStyle enum. - Added text3dConversionStyle parameter to control the conversion style for OdDgTextNode3d and OdDgText3d curve elements using the ConversionStyle enum.

  • [HOOPS Converter] Updated to HOOPS Exchange SDK 2026.2.0

  • [HOOPS Converter] Removed custom prim type tokens and fixed duplicate inputs: prefix in metallic constant token

  • [HOOPS Converter] Moved local material (“Looks”) Scope from individual meshes to the prototype root, reducing redundant material definitions in instanced assemblies

Fixed#

  • [CAD Converter] Resolved issue in omni.kit.converter.hoops_core where the filterStyle converter option was not properly applied from the GUI

  • Converting to USD can take more memory and CPU power depending on the type of data and Tessellation settings. File size is not an indicator of how fast a conversion will be or how much memory is required. In most cases, we recommend a minimum of 16 GB. Complex files will need a minimum of 32 GB of memory available for conversion.

  • PMI and BIM data is not converted for the following formats: .dgn, .jt, .fbx, .obj, .gltf, .glb, .ply, .lxo, .md5, .e57, and .pts.
