Like many things in iClone, managing cameras is... "different"... the first time you try to work with them.
- You can create multiple cameras (Create --> Camera). It's good to give them meaningful names.
- Only ONE camera is "active" at any given time.
- You need to use the TIMELINE to "switch" (control) which camera is active at any given time. Right-click on the "Switcher" row in the timeline to pick a camera at any given time, and it will put a keyframe there.
- You can preview (and render) with any single camera based on the one you select from the drop-down list.
- To observe your switching, select "Switch" from the drop-down.
A couple other quick points:
- You will want to go back to the "preview" camera to "work" on your scene without affecting your camera, so you can zoom in/out and rotate without ruining a camera setup.
- This is a good time to use the "Window --> Mini Viewport" so you have a different view open while you work
- I find it is extremely easy to forget to switch back to "preview." If you are really happy with a camera setup, you can "Lock" the camera position so you don't change it by accident.
- Remember to go back to the "Switch" camera option before you render.
I hope these hints help.
