Sometimes if I've built a complicated set, with lots of objects and people in it, I find that things get moved around by accident eg. I move an actor in one POV (say a mid-shot) then I switch to another view (say a reverse wide shot) and I seem to have moved other objects close to the actor (say a table or a part of a set). Is there a way to 'lock down' the set so this doesn't keep happening?
Thanks in advance.
P.S. FrameForge 3D Studio is still the best 'new toy' I've used in years.
