Some file formats cannot be directly imported into Unreal Engine using Datasmith, and instead the data must be converted into a file format that Datasmith understands. The plugins available for download on this page will enable your software to export the .udatasmith file format, which can then be imported into Unreal Engine using Datasmith. Many of these plugins are also compatible with Twinmotion.
Download the available installer file that matches the Unreal Engine or Twinmotion version you are using, exit your content creation software, and run the installer file to install the exporter plugin.
If you are installing these plugins on a computer that will not also have Unreal Engine installed, then you may first need to install some prerequisite dependencies for either 64-bit or 32-bit systems.
