I have used bakeResults in maya.standalone without issue on parent/
point/orient constrained attributes, so I know it can work (I know
that doesn't help much).
Is the animation not baking for the full range on the constrained
attributes? Or is it just not copying for the full range?
Re your concern with XML:
"Not only to mention if there are 200 controllers in the scene I would
have to go frame by frame for each controller and their attribute and
save the data out"
The keyframe command can query an entire animation curve, so assuming
you have a list of the attributes you wanted to query for a given
object:
obj = 'locator1'
attrs = ['tx', 'ty', 'tz']
for attr in attrs:
# When querying time and value (tc/vc), the command returns a list
# of [time, value, time, value, time, value, ...]
keys = cmds.keyframe(obj, q=True, at=attr, t=[], vc=True, tc=True)
Unfortunately if you pass it a list of attributes maya doesn't
distinguish between them in the resulting list so as far as I know you
have to do it one attribute at a time.
Assuming you're doing this to baked keys, you don't need to worry
about tangents, but if you weren't you would have to use
cmds.keyTangent as well for the weight/angle/type of each tangent. I'm
not saying you should necessarily go down this route, just that it's
not as cumbersome as you seem to have assumed.
