Wobbling Axis when Animating Rotation
Probably a real easy answer but I’ve racked my brain for hours now and need a solution. I have an object (letter). I’d like to rotate that letter like a swinging door, however I rotated my axis to make up for the slant of the letter (see pics). When I animate the rotation its not linear, HPB all change and I consistently get a wobbling effect on playback. Checked f-curves and made them linear but still get the issue. I’ve tried WORLD transform but it doesn’t do anything different even though I’m dragging off the object. I’m missing a step, just don’t know what.
Thanks

drop the letter in a Null so the null is where you want the letter to rotate around and rotate the null.

Basically does the same thing. What I think is the issue is when I rotate the NULL to the “open door” position its changing all values (HPB) instead of changing just one value. So when I close the door and playback… each value is changing over time, which doesn’t seem right if I’m rotating on one axis.
Isn’t there a way to rotate the axis point and then zero it as if thats the (0,0,0) axis? -
I believe you’re having the same problem I’m having. This is a gimbal lock issue and I haven’t yet found a solution. I’ve been tasked with animating several moves on a rubik’s cube and certain (already rotated cubes) are taking a curved path.
Maybe this little explanation might help you more than me.

I’d be happy to find a solution. Been working on this for four weeks.
