- the export menu is back for now. It also includes the "low memory export" option I posted for DenDwaler's Cathedral (which wasn't included in the official 2.49 PyPRP)
- delta animations can now be exported directly. Delta location is fine, delta rotation might not be 100% accurate (my knowledge of eulers and quaternions is limited).
Browsing older topics, it seems Plasma simply cannot handle relative animations, unfortunately. So animations are automatically converted on export to absolute coordinates.
If that's not enough, I can have a look at converting D'Lanor's scripts to the new Blender.
Also, something I forgot about animations on Blender 2.7: by default they all start at frame 0 (the same as Plasma), and I updated PyPRP to match it. So when dealing with complex animations made on version 2.49, you might want to go into the Graph Editor, enter edit mode, and grab all your markers one frame to the left.
Concerning the export menu, I'll probably replace it with an interface and the auto-paging stuff, so for now it's temporary.
