Axis Mode Bug

Create solid
Make 3D
Rotate on Y-axis any amount
switch to world axis mode
switch back to local
try to move only on the z axis

Even if you don’t switch the axis, You will get the same behavior.

Reason:

The moment you Rotate a 3D Object on any axis, Its Orientation starts intersecting the default X,Y and Z axis of AE Coordinate System. Thus when you move an object in Z-space after rotating it in Y-axis, you will notice that X coordinates are changing too as now the Orientation of Object is such that It is moving in both direction according to Default AE Coordinate System.

For Example:

Create a Solid, Make it 3D and rotate on X-axis.

Now move it in Z space and you will notice that Y coordinates are changing too.

This happens when you are moving the object in Composition using Axis handles.

If you want to move an object in just one coordinate, Change the Value in Transform Parameter.

Hope this may help.

And Its not a BUG.

I beg to differ – it is a bug.

Try moving an array of multiple objects in different quantities multiple times. Using the rotation tool and typing in a value into an orientation or rotation field has the same effect and world axis is not honored by AE.

Maybe I’m wrong though!

I’m doing a Rubik’s cube animation which should have been simple once the scene was set up. The first few moves go alright but when I get to the third move the scene (cube) starts to fall apart by rotating in different directions.

My single cubes are set up as pre-comps, my main cube and all the anchor points of the single cubes are set to the center of the scene and offset to their respective coordinates.

Something that should have been easy in world axis mode – choosing nine cubes and rotating them, and then choosing another nine cubes and rotating them and so on – cannot be done.
