In Google SketchUp, I made a simple render of a vehicle and a garage door. What I want is to animate a 45-60 second movie of some action using these objects:
1. The vehicle (forklift) approaches the garage door and stops a few feet in front of the door (starting view would be at an angle from behind and above the vehicle)
2. The vehicle is detected by a sensor mounted to the garage door (sensor will be shown as a small box mounted to the side of the garage door about halfway up that sends a signal that bounces of the vehicle - like an animation of sonar waves)
3. The garage door goes up. (As the garage door goes up, the angle swings around to see the front of the vehicle facing the door from the other side, still above and at an angle) - [if this is done in Flash, instead of moving the camera, this can be done as a cut to the other view as the door goes up]
4. The vehicle starts moving again and goes through the garage door
5. Another identical sensor on the opposite side of the door detects that the vehicle has gone through the door completely (same sensor animation - like sonar)
6. The door closes as the vehicle drives away
7. Wait about four seconds with the door closed
8. With the door closed, a person passes in front of the door and the sensor sends the waves again. This time the door does NOT move and the person continues past the door.
No audio is needed. If it is better to do this in Flash or After Effects or whatever software you want, that's fine. If it's actually in 2D and only looks like a rendering in 3D, that's fine too. In the end, what I want is a video of the action described above in at least 1024x768 resolution in any of the standard formats. I am not terribly picky about the file format as long as I can edit or convert it later.
My skills with Google SketchUp are very basic, but I put together some images of what I need. There are four images in the attached ZIP file. They show the basic sequence (but only from one side). If it helps, I can provide my Google SketchUp files for you to start from.
