Hi. I notice the Fracplanet package <http://packages.debian.org/wheezy/fracplanet> includes a Blender export function that only works with an antiquated version of Blender. I have redone this to work with a current Blender build; my code is available here <https://github.com/ldo/fracplanet>, in the “ldo” branch. I have also notified Tim Day, the developer of Fracplanet.
