Output is overscanned when using Tracked Cam with Billboards

 

@@Eiffert: I am using  DE 2024.3.0 . I am running  a Tracked Cam  project  without billboards and using a PTZ  which tracks my subject and sends tracking data to Aximmetry to control the background. That works well and tracks the talent's movement  accurately. I need to add shadows and occlusion  by using the billboards.

When I select Use Billboards in  Scene, my virtual scene and the camera image of my subject are zoomed out, giving a much longer and  wider shot than when  the Billboards are off. Any idea why the scale of the virtual set and camera image are affected. How can I fix. Thanks

Hi,

When the Use Billboards parameter is turned off, the camera's image is simply overlaid on top of the scene's image. Conversely, when you enable Use Billboards, the camera image is placed inside the scene. All the parameters in the Billboard panel will then affect the billboard, allowing you to make numerous adjustments that alter how the billboard appears when Use Billboards is turned on.

Therefore, if you have made changes in the Billboard panel and are experiencing issues when Use Billboards is turned on, I suggest trying to reset the Billboard panel's settings to see if this resolves the problem:

Also, a common mistake to be aware of is accidentally moving the virtual camera path. The virtual camera path only functions when Use Billboards is turned on. Therefore, after enabling Use Billboards, be sure to reset the Virtual Camera Path's position to its default state:
