I am a freelance animator working in Maya, and I own a copy of Maya-2011. My current project involves mocap animation files from my client, which I have to tweek and polish to a high standard. I recently realized that Maya 2012 anim files from my client has the default tangents set to the new Auto type. Since I have to work on 2011, and since Maya-2011 doesnot have Auto tangents, I see a a great deal of disparity between previews sent by my client and the ones I generate in 2011.
Is there any quick way (other than tweaking each tangent key by hand !) to get animation files from Maya 2012 to Maya 2011, preserving the integrity of the animation ?
