Animation curves on Montages are not remapped when using a 'Compatible' skeleton

Animation curves on Montages are not remapped when using a 'Compatible' skeleton

Description

[Link Removed]

From UDN:

 

If you are using the new compatible skeletons feature and you have a Montage with an attribute curve on it, the curve is not correctly mapped to the target skeleton.
So if you had two Skeletons called SK_Man and SK_Jim, each with a differing set of curves defined on them but each shared a curve called EnableFeature, and you then created a Montage targeting SK_Man which implemented the EnableFeature curve, when you play that montage using SK_Jim the curve does not get remapped properly and the curve value will either affect a different curve on SK_Jim or otherwise not work at all.

 

Steps to Reproduce

See UDN description for repro details.

  1. Have 2 compatible skeletons with different set of curves
  2. Add a new curve to both skeleton A and B
  3. Create montage mapped to skeleton A
  4. Add a curve to the new montage.
  5. Play the montage A on mesh mapped to skeleton B
  6. The curve will either affect the wrong curve, or will not work.
