Focal Distance of Vray Sperical Camera

Hi,

I am doing renderings for a 360? Panorama tour of a flat, like this one: https://pics.picmyplace.eu/presentations/project-P6-cFzfaxG4fdbm6QAAMODbToMQoqMvY/start.html

Now we have to make drone photos to generate 360? photo panoramas of them, for the backgrounds on the balcony panoramas.

My Question is: Can someone tell me how we can adjust the DSLR on the drone to generate a 360? photopanorama that fits as good as possible as a background in our rendered panorama?
For Example: Does someone know which focal distance is used when I generate a 360? pano in 3DsMax/Vray(Render Settigs/Vray-Tab/Camera/Overrride…360)

I am thankful for all kind of advices what we have to look at, to match the 2 panormas.

Thanks,
Max

Isn’t focal length irrelevant if you’re generating an equliateral 360 image? You’ll have a series of stitched together images, the focal length will only make a difference in how many images are used to stitch together the pano.
