We are developing games for oil rig engineering. Is it possible to make game background filled as panoramic image in unity3d (as spherical or cubic panorama). We would like to add our other object as mesh generated in MAYA.
Yes it is possible!
make a material with your picture on it and use a skybox shader (comes as default under renderFX → skybox).
then go to edit → render settings and assign your material as skybox.
