Simplygon 10.0.4600.0 ​

New features ​

Improvements & changes ​

  • Fixed issue related to Morpher writeback when using AllowUnsafeImport-flag.

Documentation ​

  • Updated with Simplygon 9 upgrade information.

Bug fixes ​

API ​

  • Fix to Python wrapping code, so SetUserData now accepts a list of data
  • Fixed a regression in the texture shading node, which did not update transformations correctly.
  • Scene::Append now handles duplicate textures correctly when appending scenes with identical texture names.
  • VertexWeightSettings now works more as expected with QuadReductionProcessor. Vertex colors can now be used for reduction weighting.
  • Fixed some broken log messages.

Simplygon 10.0.1400.0 ​

New features ​

API ​

  • Modular seams, enabling gapless reduction between modular assets

  • Support for quad reduction

    • Feature overview
    • Quad support in GeometryData by linking adjacent triangles with the new QuadFlags triangle field.
    • FBX importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
    • OBJ importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
    • USD importer/exporter populates and uses the QuadFlags field to import and export quad geometry data.
    • Quads that pass though the triangle-based processors are maintained when possible, but will convert to triangles as required by mesh modifications and reduction operations.
    • Triangles which are marked as part of quads are automatically quadrangulated on export.
    • GeometryData::ValidateQuadFlags() can be used to check the validity of user-set quad flags.
    • Quad reduction processor and pipeline
      • New processor/pipeline that works on structured quad meshes and collapses entire strips of quads at a time.
      • Appropriate for LOD0 reductions as structured input -> structured output.
      • Settings for basic reduction targets; Ratio, Count, MaxDev, OnScreenSize
      • Limitations
        • May stop reduction ahead of reduction target if no more acceptable collapses are found.
        • Does currently not behave well on unstructured quad meshes, works best on authored content with regular topology.
        • Primarily tries to remove quads in geometry with mixed polygon types, and ignores triangles unless they are adjacent to quads.
        • Count and Ratio reduction targets will include triangles in stop condition calculation.
        • VertexWeights are not supported. The field must be removed completely from the geometry as it being present leads to unpredictable behavior.
        • Vertex welding is not yet supported.

  • Tessellated Attributes in API

    • Added support for per-triangle implicitly stored tessellation of attributes in geometries. Supported by all processors, casting opacity and displacement (scalar or full vector displacement data)
    • VDM (Vector Displacement Maps) floating point maps (.tiff & .exr formats) can be imported and injected into displacement data in tessellated attributes

Max ​

Maya ​

License updates ​

  • New license type "Standard" added which is more resilient to license server outage.

Improvements & changes ​

Distribution ​

  • Improved container support
    • In container environments, Simplygon will fallback to CPU if GPU is not available.

API ​

  • Import/export

    • General N-gon polygon faces are automatically triangulated, and quad information is kept on import.
    • Added support for .exr file format input
    • Full support for importing, casting and exporting floating point texture data (in .tif and .exr file formats)
    • FBX exporter automatically compresses attribute fields using IndexToDirect.
    • RunImport and RunExport are renamed to Run and now returns EErrorCode, to harmonize with processors.

  • Scene data

    • Scene nodes now always generate guids for unique look up
    • Added BrightnessContrast and ColorCorrection nodes to shading network
    • Texture, material, bones and selection set tables now enforce unique names when adding or setting items.

  • Error handling

    • Error handling now supports recoverable errors in extension to the regular (unrecoverable) errors.
    • Recoverable errors from processors, importers and exporters are returned as EErrorCode enum values.
