ground ist an actor and you can find this actor under Collaboration > Environment > Ground
If you selct this actor you will be able to Change some properties. Deactivate Autofit!
Move the Ground in the viewport by using the arrows of this actor. Or Change Diameter.
If "Auto fit" is deactivated it will not be moved in the Scene.
Thank you so much for your help!
That's exactly what I needed. I've been working with Composer for just a couple of months and I hadn't yet noticed that the Ground was a collaborative actor to which I could change properties, etc.
Thanks for the quick reply
