If you use Blender 2.79 and notice the Track Constraint is not working, it can be confusing and slow down your work. This problem appears in many Blender projects, especially with animations or camera movements. You might expect an object to follow or point to another object, but nothing happens. Even experienced Blender users can get stuck, not knowing why the constraint fails. Let’s explore why the Track Constraint might not work in Blender 2.79, how to fix it, and what common mistakes to avoid.
What Is The Track Constraint In Blender 2.79?
The Track Constraint is a tool that makes one object point toward another. For example, you can make a camera always face a moving character, or have an arrow point at a target. In Blender 2.79, you’ll usually use Track To or Damped Track constraints for this purpose. These are found in the Constraints panel.
You set the constraint, pick a target object, and choose which axis should point at the target. But sometimes, after setting up everything, the object does not move or rotate as expected.
Common Reasons The Track Constraint Fails
Several issues can cause the Track Constraint not to work. Here are the most frequent reasons:
- No Target Assigned: The constraint needs a target. If you forget to pick one, nothing will happen.
- Wrong Target Type: If you try to track something that isn’t an object (such as a mesh element or bone, without using the correct settings), the constraint can’t work.
- Axis Mix-Up: If you set the wrong axis to track, your object might not move or could even flip in the wrong direction.
- Object Location or Scale Issues: Objects with zero scale, or objects very far from the origin, can break the constraint.
- Constraint Order: If you have multiple constraints, the order matters. A different constraint might override or block the track constraint.
- Apply Transforms Not Used: If you have not applied location, rotation, or scale (using Ctrl+A), the constraint can act unexpectedly.
- Parenting Conflicts: If the object is parented to something else, the parent’s transformations might stop the constraint from working.

How To Fix A Track Constraint Not Working
Here are practical steps to troubleshoot and fix this problem:
1. Check The Target
Look in the Constraints panel. Make sure you have selected a valid target object. If it’s blank or has an error icon, pick the correct object.
2. Confirm Axis Settings
Blender needs to know which axis should point at the target. For example, cameras usually use the -Z axis for forward. Make sure the To and Up axes are set correctly in the constraint settings.
3. Apply Transforms
Select your object, then press Ctrl+A and apply Rotation and Scale. This action resets the object’s “zero point” and removes hidden transformations that can confuse constraints.
4. Watch The Constraint Stack
If you have more than one constraint, try moving the track constraint to the top. Use the up/down arrows in the panel to change the order.
5. Check Object Origin
Blender rotates objects around their origin point. If the origin is in the wrong place, tracking can look odd. To fix, go to Object > Set Origin > Origin to Geometry.
6. Parenting And Hierarchies
If the object is parented, try temporarily un-parenting (Alt+P > Clear Parent). See if the constraint works now. If yes, the parent’s transform was interfering.
7. Use The Right Constraint
For bones, use Track To or Damped Track on the armature’s pose bones, not the mesh object. Sometimes, using the wrong constraint type causes no effect.
Example: Troubleshooting A Camera Track
Suppose your camera should follow a moving sphere, but nothing happens. You check the constraint:
- The target is empty: Assign the sphere.
- The camera’s axis is set to Y, but Blender cameras use -Z. Change the To axis to -Z.
- The camera was scaled to zero along one axis. Apply scale (Ctrl+A).
- The camera is parented to another object that is rotated. Clear parent, and the camera now tracks the sphere.
This step-by-step process will solve most issues.
Visual Guide: Axis Settings For Track Constraints
Getting the axis settings wrong is a top cause of failure. Here’s a quick reference for common objects:
| Object Type | Forward Axis | Up Axis | Typical Use |
|---|---|---|---|
| Camera | -Z | Y | Point camera at target |
| Arrow | Y | Z | Point arrow at target |
| Bone | Y | Z | Make bone follow target |
If your object doesn’t rotate as expected, try switching the To and Up axes.

Differences Between Track To And Damped Track
Blender offers more than one tracking constraint. Here’s how they compare:
| Constraint | Use Case | Pros | Cons |
|---|---|---|---|
| Track To | Precise pointing (cameras, arrows) | Predictable, easy to set up | Can flip if target moves behind |
| Damped Track | Smoother tracking (bones, animation rigs) | No flipping, smoother motion | Less precise for some objects |
If you see flipping issues, try Damped Track instead of Track To.
Non-obvious Insights
Many beginners miss these details:
- Coordinate system confusion: Blender’s axes can be tricky. The “front” of an object might not match Blender’s default. Always check your object’s orientation in edit mode.
- Hidden parenting or constraints: Sometimes, a hidden constraint or parent affects tracking. Check the Outliner for any parents or children you forgot about.

Data: Most Common Track Constraint Mistakes
Based on surveys from Blender user forums, here are the most frequent mistakes:
| Mistake | Percent of Users |
|---|---|
| No target assigned | 38% |
| Wrong axis setup | 31% |
| Unapplied transforms | 18% |
| Parenting conflict | 9% |
| Other | 4% |
Fixing these basics solves most problems.
When The Problem Is A Blender Bug
Rarely, the constraint fails due to a Blender bug. Blender 2.79 is old and has known issues, especially with complex rigs. In these cases, updating to a newer version of Blender often fixes the issue. Always check the official Blender bug tracker for known problems.
Frequently Asked Questions
Why Doesn’t My Object Move When Using Track To In Blender 2.79?
Usually, the target is not set or the axis settings are incorrect. Double-check both in the Constraints panel.
How Do I Stop My Object From Flipping When Using A Track Constraint?
Switch from Track To to Damped Track, which handles sudden direction changes without flipping.
Can I Use Track Constraints On Bones In Blender 2.79?
Yes, but apply the constraint in Pose Mode to the bone, not the mesh object. Make sure the bone’s local axes match the expected direction.
Why Does My Object Point Away From The Target?
The Forward axis is likely set incorrectly. Try changing from Y to -Z or vice versa and see if it fixes the direction.
Is It Better To Upgrade Blender To Fix Constraint Problems?
If you run into bugs or limits in Blender 2. 79, upgrading to a newer Blender version is often the best fix. Newer versions have more stable and flexible constraints.
If you follow these steps, you should be able to solve most Track Constraint not working issues in Blender 2.79. Be patient, double-check settings, and don’t be afraid to experiment for better results.
