Introduction

The DLL required for the Unreal DataSmith reader and writer has been removed starting in FME 2026.1. In FME 2026.1 and newer, attempting to add this reader or writer will show the format as greyed out, with a message indicating missing dependencies.

The DLL is no longer included with the FME installation. To continue using this format, please contact Support to request the required DLL.
