- Disable IK and try on flat surface.
- If problem persists, open character, select collision and in details: show collision in game. If collision is touching floor it’s the mesh
- If it’s the mesh, check if mesh is above bottom of collision (zoom in real close, also, do use ortographic mode)
If I’m not mistaken, it’s gotta be one of those.
If the problem is
- IK: check if offsets are added or if skeleton points from whick IK is cast are correct
- collision: check if floor has correct collision
- mesh: lower the mesh
