I have a very simple scene, made out of 4 elements (see attached .blend):
- A plate
- Two bars (both parented to the plate)
- An Empty (parented to the first bar, at its tip)
My target is to rotate the first bar on its Y axis, and have the second bar rotating as well, in the opposite direction, and move so that its projection is aligned with the projection of the first one.
…I achieved this, using two constraints:
- Copy rotation, inverted, on the Y axis, World Space - World Space (bar to bar)
- Copy location, X axis, World Space - Local Space (bar to the Empty)
As you can see, it works fine (just rotate the Arm1 object on his Y axis).
The problem occurs when I rotate the base plate. When I rotate the Arm1, everything mess up!
I tried all combinations of Local/World Spaces, Offset and so.
What should I do?
Thank you a lot in advance!
