Even tho I am experiencing those settings and have them present/visible within Ayon Settings and also when using Loader actions (as right click menu entry) I wasnt able to load layout neither as Alembic nor FBX

Not sure whats the issue there but I have tried whatever could work but no luck...Im just getting empty UE level and sequence no matter if FBX or Alembic been set.

Thanks for testing, it is mainly because the code doesn't get the fbx/abc loading asset data correctly. Can you please test it again by pulling the latest commit?

It works for me, and if chosen FBX it uses such repre when Load Layout action used.

Also tested with ABC and works too.

LGTM

note: we are not able to load asset in 2 different representation (Abc / FBX) atm ...as when you try to do so, it will perform check if uasset present and skips it?? something for different PR I guess

for e.g. having already mech_warrior in version 03 and Alembic ....wont let you load the same but FBX repre as the uasset already exists
