-- Unreal Skeletal Mesh and Animation Export (.psk and .psa) export script v0.0.1 --<br>
- NOTES:
- This script Exports To Unreal's PSK and PSA file formats for Skeletal Meshes and Animations. <br>
- This script DOES NOT support vertex animation! These require completely different file formats. <br>
- v0.0.1
- Initial version
- v0.0.2
- This version adds support for more than one material index!
[ - Edit by: Darknet
- v0.0.3 - v0.0.12
- This will work on UT3 and it is a stable version that work with vehicle for testing.
- Main Bone fix no dummy needed to be there.
- Just bone issues position, rotation, and offset for psk.
- The armature bone position, rotation, and the offset of the bone is fix. It was to deal with skeleton mesh export for psk.
- Animation is fix for position, offset, rotation bone support one rotation direction when armature build.
- It will convert your mesh into triangular when exporting to psk file.
- Did not work with psa export yet.
- v0.0.13
- The animatoin will support different bone rotations when export the animation.
- v0.0.14
- Fixed Action set keys frames when there is no pose keys and it will ignore it.
- v0.0.15
- Fixed multiple objects when exporting to psk. Select one mesh to export to psk.

NOTES for Jan 2012 refactor (Spoof)
* THIS IS A WORK IN PROGRESS. These modifications were originally
intended for internal use and are incomplete. Use at your own risk! *
TODO
- (Blender 2.62) changes to Matrix math
- (Blender 2.62) check for long names
- option to manually set the root bone for export
CHANGES
- new bone parsing to allow advanced rigging
- identification of armature and mesh
- removed the need to apply an action to the armature
- fixed anim rate to work correctly in UDK (no more FPS fudging)
- progress reporting while processing smooth groups
- more informative logging
- code refactor for clarity and modularity
- naming conventions unified to use lowercase_with_underscore
- C++ datatypes and PSK/PSA classes remain CamelCaseStyle for clarity
- names such as 'ut' and 'unreal' unified to 'udk'
- simplification of code structure
- removed legacy code paths
USAGE
This version of the exporter is more selective over which bones are considered
part of the UDK skeletal mesh, and allows greater flexibility for adding
control bones to aid in animation.
Taking advantage of this script requires the following methodology:
* Place all exportable bones into a bone hierarchy extending from a single
root. This root bone must have use_deform enabled. All other root bones
in the armature must disable use_deform. *
The script searches for a root bone with use_deform set true and considers all
bones parented to it as part of the UDK skeletal mesh. Thus only these bones
are exported and all other bones are ignored.
This removes many restrictions on the rigger/animator, who can add control
bone hierarchies to the rig, and keyframe any element into actions. With this
approach you can build complex animation rigs in a similar vein to the Rigify
add-on, by Nathan Vegdahl. However...
* Rigify is incompatible with this script *
Rigify interlaces deformer bones within a single hierarchy making it difficult
to deconstruct for export. It also splits some meta-rig bones into multiple
deformer bones (bad for optimising a game character). I had partial success
writing a parser for the structure, but it was taking too much time and,
considering the other issues with Rigify, it was abandoned.
