Hi there 
We are experiencing some inconsistent results between our animations in Maya and their interpretation in Mecanim. Let’s say there are two animations in Maya and the end pose of the character in first animation matches the starting pose of the second animation perfectly. However, when we bring the two animations into Unity, Mecanim decides to change the rotations on the poses mentioned above so they do not match anymore. The difference and animation settings are shown on the screen shots below:
And here is the difference in the mecanim animation preview window (Note the difference between the blue and red arrows, despite the pose being exactly the same in Maya) :
I wanted to ask if anyone in the community is experiencing similar issues and if so how do you deal with them, also is Unity team aware of this problem or even if it is something we could be doing wrong on our end.
Thanks
