I did a search for "euler" on the entire forum and read all the posts. Some seemed to address this problem partially. I found out that changing axis order was important for local euler rotation, but it didn't solve much. Here is the problem I am having.
1. Make a box in the top viewport.
2. Change the rotation controller from TCB to Euler XYZ
3. Change the axis order to ZYX
4. Go to the perspective viewport.
5. Turn on animate and make sure rotation is set to local and not view
6. At frame 10 add a Y-rotation key. I just tilted the box down -30. Do the same at frame 20. (I tilted it back up +20 units.)
7. At this point if you look at your curves in trackview, there are only curves for the y-axis, which is expected. We want this. The curve goes down then up. (In trackview, highlight all 3 rotations so you can watch all 3 curves change while you animate)
8. Now go to frame 30 and set a keyframe for a Z rotation. (Only the key for Z is adjusted, just like we want, while "dormant" keys for X and Y are created. So far so good.)
But this is where things get screwy.
09. Staying at frame 30, set a key for Y axis now.
It adjusts the curves for Y BUT, it also starts to adjust the curves for Z and X. If you have the Z-axis curves in trackview visible while you animate, you can see that the key set for Z at frame 30 moves when you animate the Y-axis. Also go watch the X-axis. The key at frame 30 for the X-axis also moves.
This is the problem I've been having. Any suggestions? I talked to both a long time Maya user and a long time Lightwave user. Both use Euler for rotations and haven't run into this problem. They only run into gimble lock. The box represents a hand I am trying to animate. Right now I'm stuck staying with TCB rotations until I find a solution. Any help would be great! :)
Thanks,
