Why are my retargeted character's feet tilted?

Retargeting maps muscles between Avatars. If the source rig's foot rest pose differs from your character's T-pose, the retarget tilts. Open the Avatar's Configure window, fix the T-pose, and re-import.

How do I fix the T-pose?

Avatar → Configure Avatar → Pose menu → Enforce T-Pose. Manual tweak each bone if needed (especially feet flat to ground). Apply, exit Configure.

Should I enable Foot IK?

Yes, on the Animator layer. Foot IK runs at runtime to plant feet on the actual ground regardless of clip imperfections. Doesn't fix retarget issues but compensates for slight mismatches.

Fix: Unity Humanoid Retargeted Feet Tilted

Quick answer: Open the Avatar → Configure Avatar. Enforce T-Pose. Tweak foot rotation flat to ground. Apply. Re-imported animations retarget cleanly. Add Foot IK for ground correction at runtime.

You buy a Mixamo animation. Apply to your character. Feet tilt outward 10 degrees. Avatar T-pose mismatch with the source rig.

The Symptom

Retargeted humanoid animations show consistent foot rotation off-axis. Source character (in Mixamo) looks fine; your character looks broken.

The Fix

Step 1: Configure Avatar. Select the FBX. Inspector → Rig tab → Configure. Pose menu → Enforce T-Pose. Adjust each bone manually if Enforce isn’t enough — especially feet flat, knees forward, arms horizontal.

Step 2: Apply. Done button. Avatar saved. Re-import animations that use this Avatar.

Step 3: Foot IK at runtime. See Mecanim foot slide for the script. Provides ground-aware foot placement on top of retargeted animation.

Mixamo Specifically

Mixamo’s default rig has a slight foot tilt that mismatches some character T-poses. Fix in your Avatar’s Configure rather than tweaking every animation.

Verifying

Idle animation should show feet flat to ground. Walk: feet stride correctly. If still tilted, the Avatar’s T-pose isn’t the same as the source rig’s assumption.

“Configure Avatar T-pose. Re-import. Foot IK on top. Feet flat.”

T-pose right. Retarget cleans. Feet flat.
