Hello everyone, I’m working on a third-person game project. I created a character in VRoid, modified it in Blender, and exported it as an FBX. However, I’m running into a severe issue.
After importing the character’s FBX into UE, I created an IK Rig and set up the Skeletal Mesh. Everything displays perfectly fine up to this point. But as soon as I start “Adding an IK Retarget Chain”, the character’s mesh suddenly flies into the air.
I can’t figure out why. The issue seems to be isolated to the mesh itself based on my testing:
-
If I use the Mannequin’s IK Rig with my character’s mesh, my mesh still flies into the air.
-
If I use my character’s IK Rig with the Mannequin’s mesh, the Mannequin works normally.
It feels like some residual scaling or matrix data in my mesh’s bind pose is causing the Root bone to instantly scale up 5000x during the retargeting solve. Any help or insights would be greatly appreciated!
