Scaling Move Flips Camera Upside Down - Initialize Scaling¶
Summary¶
During scaled master/slave moves, Flair can choose the wrong kinematic solution and flip the camera upside down if Initialize Scaling is off. The chat thread describes a 1-point scaling workflow where setting Initialize Scaling to YES stopped the flip, then Carts Priority was used to reduce track keyframes for the scaled slave move.
Symptoms¶
- Scaling a move makes the robot want to flip the camera upside down.
- A slave move is smaller, but the track wants to travel farther than expected.
- The base or track appears to run away during the slave move.
- Axis graphs show limits after scaling.
- The move works only after changing Initialize Scaling or Carts Priority / kinematics settings.
Community Workflow¶
[CONFIRMED] Set Initialize Scaling to YES¶
Open Miscellaneous Setup and set Initialize Scaling to YES before building the scaled move. Heiko Matting described Init Scaling "yes" as one of the most important settings to check.

[CONFIRMED] Use 1-point scaling from matching first positions¶
Store the same first position in the scaling dialog for master and slave, choose 1-point scaling, enter the scale value, and scale to camera.
Confidence: 0.84
[CONFIRMED] Use Carts Priority to adjust track for the slave path¶
After scaling, the camera path may be shorter while track keyframes still reflect the master move. Switch to Carts Priority, adjust track values while watching the rig model and axis graphs, then use Convert when returning to Axis Priority.

| 2022-11-29 07:30 | Heiko Matting | "Choose 1point, your scaling value, and scale to camera." |
| 2022-11-29 07:30 | Heiko Matting | "Switch to carts priority ... put some smaller values into the track axis for your keyframes." |
| 2022-11-29 08:04 | Heiko Matting | "Take care to use the 'convert' button to recalculate axis positions after changing back from carts, not just 'apply' the dialog!" |
