Root motion rotation not applied in blend tree

Hi all,

I was trying to build a 2d blend tree that incorporated both forward motion and left/right turning. For some reason the turns weren't getting applied to the rotation of the asset so it stayed facing in it's original forward direction.

In an effort to debug I paired the tree right back to a single turn animation and the root motion rotation still doesn't get applied. After the animation plays a loop the character resets to it's original y rotation.

The problem only occurs in (any) a blend tree. Playing the animations in normal motion fields yields the expected result which is a character turning and facing a new direction.

My repo with a 1d blend tree uses this set up:



Even in the preview window I get the behaviour. If I preview the anim with the 'right_turn_90' selected, correct rotation is applied and avatar steps around in a circle. If I select the Blend Tree and it preview, the character repeats turning over the same 90 degree arc.

Is there anything special I need to do to have root motion rotation applied in a blend tree?

All the best.

A.
