I am creating a short video and i want to inculde something like this, https://vimeo.com/11170765 i have a 3d image of a ball, and want to replace the plus sign in the video with the ball. How can i do this?
You can use CC Sphere to create a "3d" ball/sphere, but it looks to me like the plus model was created in a 3d program like Cinema 4D, then brought into AE for compositing, given the relfections and stuff.
If you go to videocopilot.net you can find a tutorial on glass spheres which might give you some clues about creating reflection maps right inside of After Effects, but an actual 3D program like C4D would probably give better results.
Anyone feel free to correct me if i'm wrong
