NOTE                For a quick overview of the main features new in Pixyz Studio 2021.1, please visit this page.


  • [Import] "GDSII" format: Added support of GDSII format
  • [Import] All formats: Translation of "CAD API Failed Errors" to understandable messages
  • [Export] "glb" format: Added export compressed .glb files using Draco mesh compression
  • [Export] "JT" format: Added 'JTExportVersion' parameter to choose the JT version at export
  • [Export] All formats: Added 'ExportTextureFormat' parameter allowing to choose the format when exporting images /textures between PNG and JPEG
  • [Export] Added the export textures in PNG or JPEG, with parameterization of quality/compression
  • [Function] Added 'core.getMemoryUsagePeak' function to log maximum amount of RAM bytes used during a process
  • [Miscellaneous] Support of "emissive" maps in PBR materials: import, export and baking supported
  • [Scripting] Added method "Concat" on strings in Filter expressions
  • [System] Added workaround to fix display issue when 2 screens are used. See this page.
  • [Tools] Added a CLI tool to publish .pxzext from scenario plugin sources automatically
  • [UI] Added "Vertex Offset" function in the "Mesh" menu, with predefined presets
  • [UX] Added "Stop" button in the interface to interrupt the execution of a process
  • [UX] Added "Duplicate Without Instance" functionality ("Edit" menu) to quickly duplicate a selection of occurrences in the Product Structure
  • [Viewer] Added a cross cursor to indicate when Selection Mode is set to a sub-Part mode (ConnectedMesh, Patch, Polygon)


  • [Import] "glTF" format: Updated format to import metadata/custom properties (extras)
  • [Import] "glTF" format: Updated format to import textures tiling
  • [Import] "Rhino" format: Updated format to import curves as BRep (that can be tessellaated)
  • [Import] Removed 'Convert From Zup To Yup' import parameter from the Preferences (already disabled and replaced by 'Flip Coordinate System' parameter)
  • [Export] "glTF" format: Updated format to remove a useless root node created at export
  • [Export] "OBJ" format: Updated format to support vertices with negative indices at import
  • [Function] "List Part SubMaterials" was updated to return 0 when no material is applied (instead of empty)
  • [Function] Updated  "Select By Maximum Size" function to be run on a selection instead of the whole scene + parameter to include hidden parts or not
  • [Function] Added a 'Combine Meshes' parameter to the "Merge Parts By Materials" function to merge parts by visible materials (and not by identical material property only)
  • [Function] Boosted "Decimate Point Clouds" function execution speed (Studio only)
  • [Function] Updated "Decimate To Target" function optimized to handle very large models requiring a lot of RAM
  • [Function] Updated "Merge By Tree Level" function to transfer common parent's material on the resulting part
  • [Function] Updated "ProxyMesh+Bake" function to properly bake Normal Maps even if tangents are not present on the source model
  • [Function] Updated "Resize textures" function to resize all textures applied to a selection of multiple occurrences at once.
  • [Function] Updated "Resize textures" function with a new "Keep Texture Ratio" parameter allowing to reduce texture resolution whilst keeping texture ratio (maximum side is used)
  • [Function][Scripting] Updated "getVertexCount" function with "Count Merged Vertices" parameter, to count all vertices (including ones merged by Pixyz for performances purposes)
  • [Viewer] Viewer is automatically paused (and cannot be manipulated) during the execution of the functions optimizing the scene hierarchy (like "Merge Parts"), which was potentially slowed downed by continuous refresh


  • [Import] "glTF" format: Fixed bug with AO map when importing glTF not read properly
  • [Import] "glTF" format: fixed textures unproperly generated and named at import
  • [Import] "JT" format: Fixed 'PMIReplaceBlackColor' import parameter not working with JT files
  • [Import] "PLMXML" format: Fixed bug at import when decoding special Chinese characters in file name
  • [Import] "SolidWorks" format: Fixed potential blocking when trying to import .sldasm files
  • [Import][Export] "FBX, USD, GLTF" formats: fixed several bugs with animations at import and export
  • [Export] "FBX" format: Fixed potential crash when exporting a selection as an FBX file
  • [Export] "glTF" format: Fixed instability at export when blending opacity information in the albedo map
  • [Export] "glTF" format: Fixed some CAD Lines not exported correctly in glTF format
  • [Export] "USD" formats: Fixed models being shattered when exporting with .usdz, .usda and .usdc formats
  • [Function] Fixed "(Smart) Hidden Removal" functions running slow with the level set to "Parts"
  • [Function] Fixed "Delete Entities" function unstable in some cases
  • [Function] Fixed "ProxyMesh + Bake" function with parameters that were inverted, giving unexpected results
  • [Function] Fixed "Scale vector is null" error when cloning (copy/pasting) animated models
  • [Function] Fixed "Separate Selection" not working with the "Patch" selection mode in some cases
  • [PMI/FTA]Fixed bug with reading PMI with *.JT files
  • [Tools][Advanced Search] Fixed size of UI element for the conditions
  • [Tools][Advanced Search] Fixed bug with Queries listed in "Last Search Done" section when starting the software
  • [Tools][Explode] Fixed bug with visual behaviour IsExplodeCenter not working
  • [UI] Fixed bug which was causing the disappearing of Actions Top Bar when quitting Studio with a right click
  • [UI] Fixed bug with Create Occurrence Group from selection which didn't update selection indicator
  • [UI] Fixed cleaness/sharpness of UI when scaling display in windows config
  • [UX] Fixed a bug where moving Pivot Point only was very slow

Known issues

  • When Pixyz Studio is launched on a secondary monitor, the Viewer appears white and the scene is not displayed. This is issue is caused by a conflict between nVidia GPUs and another software. Check out this page for a workaround!
  • Animations exported in the USD formats (.usda, .usdc and .usdz files) might not behave properly
