I don’t know what kind of technology, skybox or photodome, should be used for the background around the model? I can’t combine 3D model and background perfectly. What I want to know is whether the background should use sky box or photo dome, and whether the camera should use universal camera? If it is a sky box, then if the ground of 3D model is not square, should sky box also be non cuboid?
