hello, im new to unreal and am having a hard time, i found a tutorial on using VRM’s in unreal with the plugin VRM4U and gave it a shot. Now im having an issue where my characters feet are all kinds of twisted up and cant find a video or post on how to fix this specific issue. can anyone help? pic attached of said twisted feet.
Welcome to Unreal! Twisted/rotated feet is a very common issue with VRM4U, especially after importing and retargeting.This usually happens because of problems with the auto-generated IK Rig and IK Retargeter that VRM4U creates.Quick Fixes to Try:
-
Fix the IK Rig (Most Common Solution)
-
In the Content Browser, find the IK Rig asset for your character (usually named something like IK_[YourCharacterName] or IK_[ModelName]Mannequin).
-
Open it.
-
Look at the Left Foot and Right Foot chains.
-
Delete or disable the Toe Base IK goals (they often cause twisting in UE 5.7+).
-
Make sure the foot chain ends properly at the foot or ankle bone.
-
-
Check Retargeting Settings
-
Open the IK Retargeter asset (VRM4U usually creates one automatically).
-
In the chain mapping:
-
Set Foot IK bones correctly.
-
Try changing Translation Mode on the foot/leg chains to Globally Scaled.
-
-
Re-apply the retarget and test your animation.
-
-
Other Quick Checks
-
In your Animation Blueprint, make sure you’re using the correct IK Retargeter.
-
Try disabling Foot IK temporarily in the AnimBP to see if the twist goes away (this helps isolate the problem).
-
In the VRM Import settings, check options like VRM Retarget or Auto Generate IK Rig.
