 ::::::-Some of the problems are caused by Z-up vs. Y-up. Converting geometry from Z-up to Y-up is easy but I seem to have problems converting animations (and Softimage seems to have the same problems)
 ::::::-Another problem is that ColladaMAX exports a type of animation interpolation that OniSplit does not handle (TCB). I'll add support for that if I can figure out what TCB means. Until then the "sample animation" option is a good workaround (and keep in mind that you need 60fps, not 30 like in your fbx exporter screenshot).
+:::::::Autodesk Reference: TCB Controllers
+::::::::''"TCB Controllers produce curve-based animation much like Bezier controllers. However, TCB controllers do not use tangent types or adjustable tangent handles. They use fields to adjust the Tension, Continuity, and Bias of the animation.''
+::::::::''This controller works well as a Position controller in conjunction with the Motion panel > Trajectories display of an object. With sub-object keys turned on and the Key Info dialog for a key displayed (right-click and select Key Info on the selected key to display Key Info properties), you can change the parameters in the Key Info dialog and see the trajectory path change. This allows for very precise control of an object's trajectory with visual feedback.''
+::::::::''Euler XYZ is now the default rotation controller in 3ds Max. The TCB Rotation controller was the default rotation controller for files created in versions 4 and earlier.''
+::::::::''Tip: Euler XYZ behaves very differently than TCB rotations. Users upgrading from versions 4 or earlier might have difficulty adapting to the differences between these controllers. If you are used to working with TCB rotations, you can reassign it to be the default rotation controller. "''
+:::::::I had noticed that 3ds has 2 kinds of keys per rotation/position. One kind lists only position and rotation keys when I right-click a key, and it's rotation curves don't show in the curve editor, while the other lists x, y, and z for position & rotation. The former appears to be TCB. I'm not sure how I ended up with TCB, but I believe I converted them by "collapsing transforms", and so here's another dae: [http://www.filefront.com/14519017/walking%20non-tcb.DAE non-tcb walking animation .dae] --[[User:Bobbysoon|Bobbysoon]] 18:24, 12 September 2009 (UTC)
 ::::::-Autodesk has a free "FBX Converter" that can be used to convert from .fbx to .dae (and back). It can also convert from .3ds to .fbx. See if that can be used as an alternative to ColladaMAX. Download here: [http://usa.autodesk.com/adsk/servlet/item?siteID=123112&id=10775855 FBX Converter]
 ::::::-I'd suggest that this animation discussion be moved to a different page. It's getting long and we've yet to see the end of it.
