Hip Foot and Waist Tracker Placement for Full Body Tracking
Jul
For SlimeVR, place the Waist tracker above the hip around belly-button level, place the Hip tracker lower at the belt line, and place each Foot tracker on top of the foot. The saved body role must match the point where the tracker is worn, and the mounting orientation in SlimeVR must match the direction the physical device faces.
This page is the anatomical location map for those three roles. For the order in which to label, wear, check, and calibrate a complete set, use the pre-calibration wear checklist. Questions about tightness, comfort, clothing contact, or sliding belong in the VR tracker strap fit guide.
Use this hip, waist and foot location map
Hip and waist are often used as if they mean the same place, but SlimeVR lists them as separate roles and separate recommended mounting points. Foot is also different from the Lower Leg role. Start with the role shown in SlimeVR, then use the matching row below.
| SlimeVR role | Recommended physical point | Recommended direction | Location check |
|---|---|---|---|
| Waist | Above the hip, around belly-button level | Facing forward or to the side, depending on build | The point should move when you bend your torso |
| Hip | At the belt line | Facing forward or back | Confirm that it is the lower Hip point, not the higher Waist point |
| Foot | On top of each foot | Tracker “up” toward the ankle; tracker “front” toward the ceiling | Confirm left/right roles and keep the device direction unchanged |
These are recommended reference points, not a promise that one centimeter-perfect spot works for every body. SlimeVR notes that body shapes differ and allows alternative positions on the designated body part. Change one point at a time, keep the assigned role accurate, and check that the physical device still moves with the body segment it represents.
Read Waist and Hip as two torso roles
The Waist role is the higher torso point—above the hip around belly-button level—while the Hip role is lower at the belt line. This page keeps only that map relationship; sitting, leaning, and waist repeatability tests belong in the waist tracker placement deep dive.
If your setup uses both Waist and Hip roles, do not stack two devices at an indistinguishable point and assume the software will sort them out. Check the label or device name, confirm the saved role, and identify the higher Waist point and lower Hip point separately. If your tracker layout uses only one of those roles, follow the body role assigned in your configuration rather than adding an unassigned location from a different layout.
This distinction also keeps troubleshooting honest. A tracker described as “waist” in conversation may actually be assigned as Hip in SlimeVR. Before changing calibration or body proportions, write down the role shown by the software and the real physical point where the tracker is mounted.
Add Foot as a separate lower-body role
The Foot role belongs on top of the foot, with tracker “up” toward the ankle and tracker “front” toward the ceiling; it is distinct from the Lower Leg role at the ankle. This page keeps only that map-level relationship, while footwear, movement, sitting, and foot-slide checks belong in the foot tracker placement guide.
Keep the map tied to the saved roles
A body point becomes useful only when its saved role matches the map. Confirm that Waist, Hip, and paired Foot labels identify the physical devices actually worn at those points; use the pre-calibration wear checklist linked above for the complete mounting-orientation and wear-order sequence.
Keep body proportions separate from this step. SlimeVR’s Hip offset and Foot shift change the relationship between physical and virtual skeleton points; they do not replace correct physical placement. Confirm body location, role, and mounting direction before changing skeleton values.
Verify the map before leaving this page
- Read the assigned role for each physical tracker in SlimeVR.
- Place Waist above the hip near belly-button level, Hip at the belt line, and Foot on top of the foot only when those roles exist in your layout.
- Confirm left and right assignments for the paired Foot points.
- Stand straight and match the configured mounting direction to the physical device.
- Bend slightly for the Waist point, turn for the Hip point, and take a small step for the Foot points.
- If the locations and directions remain correct, continue to the broader setup and calibration workflow.
Use the map when reviewing a tracker layout
Once you know whether your planned layout uses Waist, Hip, Foot, or only a subset of those roles, review FBTKit tracker options with this body-point map. Compare the listed setup notes with the roles you intend to wear, then return to the pre-calibration checklist.

FAQ
How are Waist and Hip roles different in the same SlimeVR body map?
Waist is the higher torso role above the hip around belly-button level, while Hip is the lower role at the belt line. Treat them as separate saved roles rather than two names for one point.
How should Waist, Hip, and Foot roles be read as one map?
Read the map from the torso to the floor: Waist above the hip, Hip at the belt line, and each Foot role on top of the foot. The saved role on every device should match that physical point.
Does every SlimeVR tracker layout use all three roles?
No. Tracker layouts use different combinations of body roles. Follow the roles assigned in your configuration and do not add a Waist, Hip, or Foot point only because it appears in this reference map.
Why must the saved role match the body-location map?
SlimeVR interprets a physical tracker through its assigned role. A device worn at a different body point without the matching role creates a location mismatch before calibration begins.
What should I do after the body-location map is correct?
Confirm left and right assignments and mounting orientation, then use the pre-calibration wear checklist and the broader setup workflow. Keep strap fit and specialist movement tests in their dedicated guides.
