I just purchased an enterprise version, it really is so good. After more usage I've found a usable workaround to the above. It doesnt allow such complex navigation as suggested above but the ability to load new sets of images via the api/hyperlink functionality allows for the virtual tour type of naviagtion i require. I should RTFM before posting on here!
The above would really open this up for me but for the moment I'll use the api/hyperlink workaround as I've got it working well in some tests.
The only problem I think I'm going to really hit is load times. My animations are large and have hundreds of frames. It would be handy to have a load buffer option. (ie load XX% or XX frames before starting)
Also, it would really help to pre-load the extra linked image sets, By this I'd like all the images in the linked sets preloaded in the background, so when I click to load a new "scene/set" via the api/hyperlink option the images have already been loaded after the originals scenes images had loaded. A preload api hyperlink option. I hope that makes sense!
Seriously cool software/scripts. If you have a sharable email I can fire over a private dev link to my project? It may explain further where I'm at with this idea.
