-- Unreal Skeletal Mesh and Animation Export (.psk and .psa) export script v0.0.1 --
- NOTES:
- This script Exports To Unreal's PSK and PSA file formats for Skeletal Meshes and Animations.
- This script DOES NOT support vertex animation! These require completely different file formats.
- 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.
- ]
- v0.1.1
