Just did a quick test importing a 30 frame animation of the Daz BlackHawk (SeaHawk texture used) using motion blur on the blades rather than using a blur prop, but just to confirm that this works ok, and all default import options used - I just tweaked the camera angle, focal length and used a preset GA atmosphere.

(Should have removed certain non SeaHawk props but they are in green - oops more haste etc...)

Hope this helps - even if not the identical UH-60 model
