Why do I get a "Multiple precompiled assemblies" error in Unity?

Unity version 2021 gives a "NotSupportedException: importMaterials has been removed. Use materialImportMode instead" error when importing Tridify BIM Tools to a Unity project.

We are working to fix the issue. In the meantime, this is how you get the plugin to work normally:

  • Open a new project or delete the Tridify folder from your project's Assets folder
  • In Unity's Package Manager, select Tridify BIM Tools and click Import
  • In the Import Unity Package window, go to Tridify>Plugins and deselect Newtonsoft.Json.dll
  • Import the package
