Hi, I am currently encountering a scaling issue while setting up an IK Retargeter in Unreal Engine 5.7.
When I retarget my animation, the Hips translation (location) seems to be multiplied by roughly 100. As a result, the character floats extremely high in the air or moves drastically far away from the root.
When I turned off the retarget, the models seems to be in the right place.
Here is my workflow:
-
I am using a workflow where I bake (plot) the motion onto the target model using MotionBuilder beforehand.
-
I import this baked animation and the model into UE and set it as the Source in the IK Retargeter.
-
I import the same model with no animation and set it as the Target in the retargeter.
-
When I create the IK rig, I select “Auto Create Retarget Chains” for each model.
Has anyone experienced this specific unit scale issue when using IK Retargeting?
I suspect it is related to the FBX import settings or the scene unit conversion, but I’m not sure how to fix this within the IK Retargeter pipeline.
Any advice would be appreciated. Thanks!
