Prefab rotation offset is ignored on prefab instance at runtime

Asset Importers



Priority: 2Necessary for shipping a final release


Severity: 2Core functionality majorly impacted

When entering runtime (Editor>Play) the prefab rotation offset, of 90' in this case, is ignored and causes the prefab to be offset by 90' at runtime.
This is my best guess at what the issues is, but definitely a regression causing my Generic Root Motion to be aligned down the X-axis, instead of the expected Z-axis forward direction.

- Import attached "Prefab_RM_bug.unitypackage" into a new Project
- Drop "CAVECRAWLER" prefab into scene
- Click the Editor Play button...
Bug: with the root selected, notice that the forward direction of the creature down the local X-axis, 90' off the expected orientation... use arrows to move.

Expected: the forward direction of the creature down the local Z-axis.

this is a regression...
