Also do we have to add licenses to every software?

Thank you for hard work

These are all included in the license, no additional licenses needed. However Aximmetry.Renderer is only available from the Professional license, since it's a part of the multi-machine system.

Please watch this for a quick overview of the apps:

And here is a doc on the multi-machine system:

Aximmetry.CameraCalib is for performing lens calibration when you use camera tracking systems that do not have their own lens calibration system. Its documentation will be released soon.
