Mirroring Skeletons

HkbEditor also covers some more obscure corner cases. One of them is mirroring skeletons. This is useful when you have an animation and want to flip it left <-> right without editing it. As FromSoft never uses this, most characters are not properly setup for this.

Example

This process requires a Skeleton.xml file. To generate it, either use Havok's FileConvert.exe --xml {Skeleton.hkx} {Skeleton.xml}, or use Havok Content Tools. For the latter, prune all animation data except for the skeleton, then write to platform as XML. If all of this sounds like arcane sorcery, ask around on ?ServerName? and someone can probably send you the .xml.

In order to fix a character's mirror definitions, select Tools -> Mirror Skeleton. In the new dialog, first load the Skeleton.xml file for your character. Then select Auto Mirror at the bottom. This will generate a mirrored bone mapping based on the _L/_R suffixes of the bones. Save the resulting xml to the Character folder of your extracted behbnd.dcx and convert it back using HKLib.

To mirror an animation, find the corresponding hkbClipGenerator and set the MIRROR flag.
