I have eight icons arranged in a circle, a Null object in the centre, and a camera that's parented to the Null. Each icon is set to be a 3D layer, and Auto-Oriented towards the camera. The camera is Auto-Oriented to Point of Interest, and parented to the Null, so that I can adjust the Z rotation of the Null to have the camera orbit the circle (producing the effect that the circle of icons is carouselling around).
Everything else is perfect, but the icons on the sides are somehow inheriting quite a dramatic Z orientation / rotation. I've attached a screenshot below to illustrate what I mean.
I tried this expression, but it made the problem worse, and I don't have the expression skills to adapt it to my needs.
How can I have each icon always face the camera, but remain fully level without manually adding keyframes to compensate?
