Ah, the movie node. Yes, I've experimented with this node. It's using AVI, which is not really an image sequence, and Octane cannot decode the image at a certain timeframe. If Poser supported a true image sequence (ie. image01.jpg through to image76.jpg for the first 76 frames) like C4D, lightwave, etc, then this function could easily be added to the Poser plugin. But without that it is complex - and the plugin needs new screens to allow the user to specify the image sequence. It's on the list of enhancements to add, but unlikely to be done for a couple of months.
