You cannot use mouse combination for that, but if you want to specify a constant Focus Distance  (or you want to animate it in some way from Aximmetry) you can override the Cam Focus parameter embedded in Control Data using a Set Collection Scalar:

Value is in meters.

This is great!.. Is there similar a way to also adjust Unreal's (Aximmetry Camera) Aperture as well as focal distance within Aximmetry?  We also  purchased the Glassmark lens encoder as well, is there a tutorial or an article on how to install and use it with Aximmetry? We purchased the Professional Version of Aximmetry Based on Richard's setup at Virtual Star Studios and are creating Matching Systems (One in Västerhaninge and one in Hollywood). We're setting it up this week.

Thanks!

Hi Scott,

Aperture is unfortunately not exposed currently from the Aximmetry_Cam blueprint (we may add this in the future), but you can expose it if you are familiar with the blueprint programming.

In order to use any kind of lens encoder, including Glassmark, you need the Broadcast Edition (Richard has it, too).
In this case you would not need the hack above, you could handle the focus via the lens calibration procedure as intended.

Hi,

Aximmetry 2025.2.0 BETA has just been released.
This update introduces general handling of camera aperture settings throughout the system:

• Calibration Profiles now can contain a mapping between the raw Iris Encoder values and the F-number (called Aperture throughout the system). It can be edited in the Basic Calibrator app (or directly in the XML file).
• Iris encoder value is read from protocols that support it. (Free-D officially does not support it, but some tracking systems like HTC Vive Mars use the spare "user" field for that purpose, and Aximmetry reads that.)
• Some camera tracking systems and protocols are capable of sending the final aperture value (Canon CV Protocol, NCam, Trackmen, AGTP). In these cases this value is used.
• For Virtual Camera paths, the aperture values can be defined for the A, B points both by mouse combination (Alt + Space + Right Mouse) or numerically.
• Record_3-Audio: aperture is added as an animated user property to the FBX.

Warmest regards,
