Previous Datasmith plugin has the feature ‘Conversion Option’. The integrated Datasmith for Unreal Engine 4.25.3 doesn’t have that option!
Nobody expects Datasmith to support Maya? 3dmax has been around for a long time, why isn’t there any info on Datasmith for Maya?
The team ran some tests lately and a lot of information between Maya and Unreal can already be carried through USD. This is making a Maya datasmith exporter a low priority.
