As for having animated textures and to share my answer this recent Refracty's request, you can find a modified version of the lastest bazuka's exporter script at this time here : maya2octane_tchoa.mel
As it is some 'side test release' you've got to use the 'maya2octane_tchoa' command to get the window.
This concern the few lines I added to the current bazuka's script to have 'all' textures animated.Only animated file textures in maya will be replaced while managing octane's animation rendering with maya.
So it's a bit tricky but suppose you've created an animated texture somewhere and plugged the first element right into an octane's texture reader node... you can have it changed at frame time by creating a corresponding, animated file node in maya as the script will replace it each new frame.
You can report bugs here as it hasn't been tested a lot...
Now it's up to bazuka to include this modification/feature and update the download section here.
Have a good end of the year!
