FBX: Camera imports to Matinee with skewed position and rotation

Branch Build Label Changelist
UE4-Main UE4_[2013-08-27_14.24] 1799942
 
DESCRIPTION: When importing an animated camera from Maya into Matinee, the placement of the camera is changed (shifted 90 degrees counterclockwise), although the relative animation remains intact.
 
ADDITIONAL INFO:
I have Maya's setting as Y-up, which actually allows for the proper orientation of maps when imported/exported.
 
Camera transformations on frame 0:
 
Transformation Maya UE4
Translate X 2140.45 775.39
Translate Y 251.74 -2140.45
Translate Z 775.39 251.74
Rotate X -8.4 0
Rotate Y 70.4 -8.39
Rotate Z 0 109.59
 
Maya's TX becomes UE4's TY
Maya's TY becomes UE4's TZ
Maya's TZ becomes UE4's TX
Maya's RX becomes UE4's RY
Maya's RY is not the same anywhere in UE4
Maya's RZ becomes UE4's RX
 
SCREENSHOT:

 
WORKAROUND (From Rocket user):
In Maya the duplicated (prepped for UE4 camera) has to have:
Swapped TranslateX with TranslateZ values.
Mirrored TranslateX values from positive to negative.
Added to rotate values: RotateX +180 RotateY +90 RotateZ +180
Mirrored RotateY values from positive to negativ.
 
===============
REPRO STEPS:
1. Launch: UE4Editor.exe   (any project)
2. Create a small BSP level or use the default
3. File > Export the level as FBX
4. Import the FBX into Maya
5. Animate a Camera flying through the level in Maya
6. File > Export Selection (Camera) in Maya, save as FBX
7. In UE4, create a Matinee Data in the level
8. Open the Matinee
9. File > Import > choose the Camera FBX
 
RESULTS: Camera imports to level rotated 90 degrees counterclockwise
 
EXPECTED: Camera imports to level with same orientation as in Maya
