Hi,

1. You could run Aximmetry in Live Sync: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/obtaining-graphics-and-virtual-assets/creating-content/creating-content-for-aximmetry-de/interactive-editing-with-live-sync/
   Then, move around in the Simulate camera:
   

   Where you could switch to Wireframe mode:
   
   

   This will only be visible in the Unreal Editor, but the nanite mesh won't change compared to this Editor view in cooked mode.
   
   Note, that Nanite has a limitation when in front of billboards: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/green-screen-production/aximmetry-de-scene-setup-green-screen/#nanite-virtualized-geometry
   
   
2. Adjusting the camera's aperture (F-stop) in Unreal Engine before cooking should work in green cameras. However, note that in AR, you need to create your own Cine Camera Actor as explained here: https://my.aximmetry.com/post/3884-virtual-images-are-out-of-focus
   If you want to change the focus or overwrite it, you can do so by editing the Control Data collection data coming from the camera compound. My comment here also demonstrates how you can change the F-stop value at runtime, as well as how to edit the Control Data: https://my.aximmetry.com/post/1795-focus-control-with-tracking
   
   
3. The sensor size is saved within the Calibration Profile, so it is unnecessary to set it in Aximmetry, and hence, cannot be modified there directly.
   Note that the sensor width doesn't affect the accuracy of the calibration and tracking. The only downside of entering incorrect values is that the shown focal length values in Aximmetry won't match the real-world focal length.
   
   
4. There is no way to set AO shadow in tracked cameras, as tracked cameras behave very differently from virtual cameras. It would be much harder to define the AO shadow's position in tracked cameras because the talent can move significant distances in any direction on the billboard.
   
   
5. You likely see the wrong focal length (zoom) values due to an incorrect sensor width value or bad zoom calibration. For some camera models, it is really hard to find their sensor widths.
   Note that you can edit the Zoom value as explained in point 2. You can also use the FOV Calculator module in the Flow Editor to calculate the focal length if you specify the sensor width within it.
   
   
6. Inside the Unreal level blueprint, you should use a Get Aximmetry Transformation as explained here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/obtaining-graphics-and-virtual-assets/creating-content/creating-content-for-aximmetry-de/additional-control-with-blueprints/#get-aximmetry-transformation
   Inside Aximmetry, connect the created transformation pin of the Unreal module to a Camera Tracking module. In the Camera Tracking module, specify your third tracker as the device.
    
   

Warmest regards,

I could solve it!

Thank you for your continued support！
