I have a rectangular Sprite 3D that appears to be anchored into the scene at its centre.  That is, when I move the camera, the Sprite rotates around its centre.  I want to anchor it at the middle of the bottom edge - is there a way of doing this? (apart from making it twice as high and making the bottom half transparent, which is really messy)

I guess you’re looking for the “movePivot” functionality, found in base class Object3D.

Thanks. So would it be true to say that, roughly, PivotPoint = RegistrationPoint?

That’s been my assumption so far =)

Thanks Alexander.  Still not working, mind.  I can move the pivotPoint to any position and it won’t change anything.  I suspect this is because the pivotPoint doesn’t come into play until you rotate the Sprite locally.
