Slight Update on the .hkx animation files.
The good news is Havok behavior gives out their SDK free and the latest is able to load up the Skeletons and Animations and play/blend them all dynamically from the stand alone tool so there is hope that the Respective Exporters will be able to export Character Animations and work ingame.
Bad News is I will need some time before I can test anything as I no longer have a version of Max that the Plugin supports but there has been some talk over at NifTools so someone else may be looking into this working a working exporter/Max combination.
Animation support for Blender into Oblivion came out about 18 - 24 months ago.....this time last year I was making complete custom creatures via blender for Oblivion.
Trouble is, this time the animations are a completely new format, so we have to start from scratch again.
I'm Dling the SDK still so I do not know just how detailed it is in this regard but it should make things much easier for Amorilia this time around, and for anyone who takes over the Max Exporter if anyone steps up.
