Why Your IK Breaks in Unreal Engine 5.7 (And How to Fix It) @ProjProd

Uploaded April 2026 | Updated September 2026, 2 weeks ago

In this video, we dive into one of the most frustrating issues when working with animation in Unreal Engine 5.7: why your IK suddenly breaks even when everything seems correct ?
The problem usually isn’t the IK setup itself, but something much more subtle: joint orientation inconsistency.
We’ll show you how a single bone pointing in a different axis can completely break your IK chain, how to visualize bone axes in the Skeletal Mesh Editor, and how to quickly fix the issue by realigning your skeleton.
