@Lloyd: That's a little vague, buddy. What do you mean by 'Best?' I guess everyone has differing opinions on what's, 'best' for them.
As Katz said, with a little digging and learning the basics of Fullscreen editing, you can pretty much make any type of clip play in a given scene or narrow it down to just one or two types of clips. Depending on the scene type and layout, you may be limited to only one type of clip or all of them. You need to experiment.
We could ask Totem to do all this for us but frankly, I doubt they have the time. Anyways, those of us who got into scene creation and ***** have had way too much fun doing it ourselves 😉 There are just too many, impossible to predict variables to make every clip work perfectly in a given scene.
In a well designed scene, especially simple scenes, the right type of clip chosen should work great most of the time, with old and new cards.
To keep playing the same model, only have her cards enabled. To keep the same scene playing continuously, disable all but the one you want and make a copy of the scene folder in the data\scenes folder and rename it. Make it enabled as well.
Now you should be able to play one model and one scene indefinitely. 😜
