Video Animated Textures

I see the option to put an MP4 into the texture slot for Iclone. It works so easily in Iclone. When I go to export to USD for use in Machinima it only shows the first frame and doesn’t play. What am I missing?

Check this out, there is a example scene you can download:

So it supports on 1000 frames long img seq for now. I hope they update this soon :)
