in sandbox I imported a 3D sphere (file extension .obj) and I created a timeline in which I changed the longitude of the camera and the color (using primary light) every three seconds. I wanted to get the effect that the rotating sphere changed color. Descartes thought that the color depended on the speed of rotation of the particles of light … I saved the file but when I run it I don’t see the sphere, I only see the black screen and the time of the timeline that goes on. What could be the problem? Thank you
