    Default 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/presentat...MvY/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

    360 degree photos don't have a focal length. When people talk about 360 panos not being the right 'scale' to match their scene as a background, it's a result of objects in the pano being closer or further away from the camera than is expected in the 3d scene.

    In other words, if your pano photo is taken right next to a building, don't expect that building to suddenly appear as a small element in the background in your 3d scene. In your case that shouldn't be an issue as you are taking the pano from the same location as your building.

    Using a longer focal length on your camera just means you need to take more photos to generate the spherical image. So just use as wide as possible.

    Once you have your 360 pano I would just apply to an inverted sphere in your scene and rotate/move that to fit your view. For internal views you can get away with shooting a cylindrical pano and applying to a cylinder.
