Editing Tools/Sonic Frontiers Animation Tools (section)

== History: ==
The PXD formats were first supported by Blender scripts created by Turk645. These initial scripts allowed animation and skeleton importing for the files first found in the 2020 Olympic game. 

From Origins onward, animation data was identified by ik-01 to be compressed by [https://github.com/nfrechette/acl ACL]. An application called "FrontiersAnimDecompress" was later created by WistfulHopes, which was used to dump decompressed track data (labeled as *.outanim files) from these newly compressed formats. Included with the app were supplemental Blender scripts for importing from the dumped track data (modified from Turk645's original scripts), as well as custom scripts for exporting custom skeletons and raw track data that could later be recompressed.

The application was eventually modified into a DLL, and supplemental scripts were rewritten as one packaged add-on by AdelQue, so standalone conversion was no longer necessary. Notable additions included batch processing, corrected scaling, skeleton reorientation for mirror support, and root motion.

Handling of raw track data was recently found to be identical across all Hedgehog Engine titles. The method in this add-on to achieve correct scaling can be reused for other Hedgehog Engine games stored in [[Resources/Havok Animation|Havok animation]] formats.
