So far the only way I found to do it is to add the footage image sequence into an Octane Sky and render it with Alpha Channel OFF and "Keep Environment" ON. However, since the footage is being mapped into the Spherical Octane Sky, there is some distortion happening to it.

I'd love to be able to ...

Even though the ORBX file opens and displays fine in Standalone. Is there a setting I am missing? The renders look like Minecraft instead of clouds. Thanks!
