Known issues and limitations

Listed below are the current known limitations and issues.

General issues

  • When running a long process and the user is performing other tasks, the add-on will still import as soon as the processing is over, potentially interrupting something else.
  • Running a python script mid-processing causes Blender to forget that the processing is happening and the output is never imported back.

Scene inconsistencies

  • Since the meshes go through the glTF exporter and importer, certain geometry fields, material types, or other scene contents may disappear or be modified after processing.
  • Scene node hierarchy may also be modified.
  • Skinned meshes may behave strangely if they have transforms applied to the skeleton root.

Missing functionality

All functionality that depend on selection sets are currently disabled, including:

  • Processing selection set
  • Clipping geometry and clipping planes
  • Custom cameras for visibility culling
  • Etc.

Blender installed via Steam

We do not recommend using Simplygon with Steam's version of Blender due to following reasons:

  • We do not detect a Blender installed through Steam so you need to perform manual installation.
  • Steam auto updates of Blender can break compatibility with Simplygon add-on.

Materials

Since the meshes go through the glTF exporter and importer, the material channels that are possible to setup for casting are limited to those supported by the Blender glTF exporter.
