-The purpose of this rig is to give us much better tools to animate, compared to our [http://oni.bungie.org/forum/viewtopic.php?pid=23698#p23698 previous process in Softimage XSI] by EdT, which allowed us to animate exclusively with Forward Kinematics, which, while may work for simple, short animations done on characters with small amount of bones, it does not work well for Oni characters and animations, as it's too labour intensive and ineffective.

 There are several things worth knowing before you start creating the rig.

 ===Rotation order issue between Oni and Blender===
-The previous XSI process allowed us to get to work pretty quickly: you could simply export any animation from Oni as a COLLADA file using OniSplit, then import it to XSI and it would work without (mostly) any quirks. That is not the case with Blender.

 If you import any Oni animation into Blender as it is, the rotations will be all wrong.
-That's because Oni's rotations are stored in XYZ Euler rotation order, while Blender's XYZ is actually ZYX, it's just called XYZ.
+That's because Oni's rotations are stored in XYZ Euler rotation order, while Blender's XYZ is actually ZYX despite being called "XYZ".
-You can prove that by simply switching the rotation order of the body parts from XYZ to ZYX, as shown below - the image on the left shows KONCOMcomb_p imported to Blender without any adjustments, with the rotation order set as default Blender's XYZ, while image on the right shows the same animation after switching the rotation order to ZYX.

-Because of this, Geyser implemented the '''-blender''' argument in OniSplit, which solves this problem by converting Oni assets' rotation order from XYZ to Quaternions and then to ZYX, and vice versa when exporting assets from Blender to Oni. So that conversion flow looks as follows:
