    Question Orbital Scanning Camera

    I have an application where I need to create a render from an automated virtual camera that orbits a spherical object and produces a texture map by baking the 3D surface images into a flat 2D image that can then be used to surface a sphere. This is just like what landsat does to photograph the entire surface of the Earth and produce a 2D image. Is this possible with built-in features of LW? If not, is there a plug-in that can do it?

    Thanks

    Surface baking camera should do the trick?
    The problem is to make a good spherical UV map without tris at the pole.
    Download sIBL and use one of the spheres there. They have great UV mapping, LatLong.

    That basically sounds like an inverted panorama, the advanced camera should be able to handle that.

    Cheers,

    How would you set that up?
    I use it with Cylindrical180 in both directions to make a spherical panorama, but that won't unwrap an existing sphere in the scene.
    There are a lot of settings there that I don't really understand though...
