Did you ever get a chance to fix the Image Sequence not working in Poser Pluggin?
Image sequences were implemented by putting a coded image name into the Octane RGB Image node, which worked fine in Octane versions up to 1.20. However after that, the Octane API wipes the filename of an Image node if the file does not exist - so this method of implementing image sequences no longer works.
I have put in a change request to Otoy to rectify this. However there may be good reason for wiping the image filename if it doesn't exist, in which case the change request won't get through - and I'll need to think of anther way of doing it.
So, no news yet - but it's still on the "todo" list.
