Difference between SETS, SHOTS and SCENES
SETS ARE CONSIDERED DRESSED LOCATIONS
They are designed for generic reuse when starting a new scene in a given location, rather than for modifying a specific shot or to continuing working on a scene or sequence that you've already started on (in FrameForge terms, there is no difference between a scene or sequence, as both are defined as a series of contiguous shots located in a given set).
SETS ARE THE MOST "COMPLETE" VERSION YOU'VE BUILT
Without you doing anything special, FrameForge will automatically update your stored set with your latest additions any time you exit a set and go to a different one. Its rule of thumb is that a set is considered more complete if it has more objects on it than the previously saved version. So any time you exit a set having added objects it will update the stored version of that set.
If you find yourself on a set that is missing things that you expect to find on it, please see this article.
SHOTS ARE SPECIFIC CAMERA SETUPS
They are located in a given set, and they include all actors, cameras, lighting etc. When you reload a shot, it will be exactly as it was when you snapped it, regardless as to what you've done to the set itself since the time it was snapped. If you find that when you reload a shot you are "missing" certain elements in the set that you built later, you should use one of the percolate options to add them in.
WHEN TO USE GOTO SET
In my script I have three scenes in Ice Cream Parlor, and although there are one or two actors who are in all three scenes, most of them are not, and due to the action in each scene, the shots are very different from one scene to the next.
Thus when I am ready to start a new scene in Ice Cream Parlor, I will go to the SETS Menu and choose Goto Set, then Ice Cream Parlor and it will open just the set, without any actors or cameras, and I am ready to work on that scene without having to first delete all the actors and camera setups I'm not going to need.
WHEN TO RELOAD A SHOT AND WORK FROM IT
If you want to continue working in a given scene that you've already started, then you should NOT load a set using the Goto Set Function, but should instead, reload a shot that's already been prepared in that scene then make sure to change the insertion point in the Shot Preview Area and work from there.
IF YOU WANT THE STORED SET TO BE A SPECIFIC STATE
All you need to do is dress the set as you like and then go to the SETS menu and use the UPDATE SETS function.
