+-- 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.
+- ]
+
+- v0.1.1
