You can't export the vrscene with an animated object (the file would basically have to store the whole scene for every frame, and thus be rather huge). However, that's not the way to render animations through Vantage anyway - it's to use the Live Link, which then sends each frame over, changes only, as Vantage renders each frame. This is what is in Corona 13, so try it for yourself in the Release Candidates :) The button still calls it "exporting" the animation to Vantage, but that's not in the sense of saving a .vrscene file with the animations in it.
PS this should work with any sort of animation in the DCC - keyframed motion, light changes, material changes, particle systems, skeletal deformations, imported alembic animated objects, animation by deformers, etc. etc. :)
