I've got my zoom encoder working and everything lines up nicely now we've gone through the calibration process, but I don't see any option to access the focus data from my second encoder.
It's sending out the data via the Viper software on the same channel but I'm unsure how to access it in Aximmetry?
Hi,
Note that Aximmetry uses the Focus Distance pin. This pin gives out a value that is already adjusted, so there is no need to divide it:
You can access this pin without opening the unreal tracked camera compound, like this:
The Focus distance value is sent to Unreal through the Control Data connection. You can access and modify the Focus distance within this Control Data collection by changing the Cam Focus collection value.
Warmest regards,
That's what I thought, but the focus distance value wasn't changing when I moved the focus encoder, which was why I ended up using the focus sensor value. This was fine as I could just plug it straight back into the focus distance (with the multiplication applied). The only reason I had to edit the camera blueprint was to be able to adjust the aperture to match my lens. (This isn't hooked up by default)
Hi,
To clarify my previous misleading comment, the Focus Distance pin only works when the tracking system sends calibrated focus data or when a Calibration profile is selected with focus calibration. Currently, it is possible to make focus calibration like this in Aximmetry: https://aximmetry.com/learn/tutorials/for-studio-operators/basic-lens-calibration-without-lens-distortion/#focus-encoder
The Focus Sensor pin will return data even when there is no calibration.
You could use the previous link to make focus calibration and then you would no longer need to do your own multiplication.
Warmest regards,
I have a habit of figuring these things out as soon as I post about them...
So it turns out it's the Focus Sensor Data I waned from the camera tracking module...
That I was able to plug in to my focus value to control the focus point in UE. However, it's off by a factor of 100 so a simple divide and you can get accurate focus distances...
Aximmetry doesn't natively control the aperture (It's set to a default F2.8). I find this to be slightly off from what I tend to use in the studio (around T5.6). So you can either set this manually or edit the blueprint to access the camera aperture as a scalar from aximmetry.
