Hi Niels,

Adding extra ones is not possible yet. If you would like, we can add your request to our internal list for consideration in future releases.

In the meantime, there are possible workarounds: If you're not using focus or zoom, you can repurpose those scalar values for anything else you need to store in the FBX file. Alternatively, if focus and zoom are in use, you might be able to utilize the camera transformation's scale values instead. Another option is to record two separate FBX files simultaneously: one for standard values without any modification and another fully hijacked for any additional values you require.

Warmest regards,

Hey Eiffert,

If you can add my request to the internal list, that would be lovely! Thank you very much for taking it into consideration. 

Thanks for pointing out the workarounds, going to give that a try :)

Thanks! 

Hi Niels,

Aximmetry 2025.2.0 BETA has just been released.

The new version includes Custom Properties support for the Tracking Recorder (FBX):

This feature request has also been helpful for us because FBX files do not natively support an aperture property. By using Custom Properties, we now save the aperture value of the camera when the Record_3-Audio compound is used.

Warmest regards,
