Unreal Datasmith
Important details:
Because of important format changes, .udatasmith files exported with previous versions (0.17 and before) will no longer import correctly in Unreal.*
The 3ds Max exporter plugin is distributed and must be installed separately.
What is new for Datasmith
Improvements:
Photometric Lighting
Unreal 4.19 supports lighting units and asymmetric IES profiles. Datasmith should now transport this information from 3ds Max correctly.
Now, with similar lighting conditions (Photometric Lights or Vray IES lights and Physical Camera + Exposure), results in 3ds max and Unreal should be very similar.
New Project Template
The new Product Viewer template is available for Unreal Studio projects, which enables users to see models in VR, AR, or on a PC screen and perform basic viewing interactions.
Exporter Improvements
The 3Ds Max exporter has greatly improved performance with faster scene parsing, and visual feedback with a progress bar during the export.

Crash on export due to Sky light
Objects misplaced when non uniform xform and custom pivot
