I noticed in my last project that the Y rotation coordinates of each set is are opposite to the Y coordinates of an identical null in the comp. I had an AE layer rotate in the same location as a zax set and they were supposed to rotate in the same place - however my Zax layer was always messing up. When I realized that instead of 90 degrees I had to put -90 in my y rotation keyframe, it worked. It becomes a pain when you start having to deal with multiple rotations and you're adding, subtracting, and crossing your fingers hoping it stays in sync.
Any reason for this? Maybe the next version could fix it?
Also, on the set rotation transforms for x, y, and z, it would be great if they looked exactly like they do in AE 3D layers, meaning, with an additional column listing the number of rotations verses 360, 720, uhhh...whatever is after that :-).
In my experience, designers don't make the best mathematicians. :-)
