XCOM 2: SPARK models

Has anyone been able to extract the SPARK models from the Shen’s Last Gift dlc in XCOM2?

Normally I use UE Viewer to extract xcom models from the UPK archives,

but it looks like the UPK files for the DLC won’t load properly with UE viewer, and when I unpack the archive, all I get are texture.2d and staticmesh, which I’ve not been able to do anything with.

Any suggestions? Can someone try this?


I’m aware that the weapons and BITS were extracted to source

So is it possible it could be done for the Sparks?
