XR calibration needs a specific XR/AR license. If you'd like to try out these features to decide whether you want to purchase an XR/AR license, please

The calibration procedures aim to ensure a cohesive image while doing virtual production and set extension, by establishing a visual bridge between the real world (captured by the camera) and the virtual world (generated by Smode).
It is considered the most critical aspect of XR projects.
To initiate the calibration process, ensure you have a

There are three different calibrators:
-
XR - Latency Calibration
Automatically evaluate the amount of frame delay between sending a picture to the stage and receiving it back through the camera.

It's important to follow the order of these calibration steps.
The Geometry calibrator relies on information from the Latency calibration.
Then, the Color calibration needs the information provided by both the Geometry and Latency calibrators.
Therefore, the calibration must be done in the following order:
1) Latency
2) Geometry
3) Color
