While a tiny UI with one slider that operates on selected objects is useful, it's also extremely limited. I'm in the early stages of development on v2.0 of the tweenMachine, and wanted to let folks know what's coming. This will be a major update with a number of new features, including:
Sets: Users will be able to create custom sliders that affect a specific set of controls. With this feature, you can more easily sculpt the start of a breakdown pose without selecting a single object. For example, make a slider that affects the entire body, another that only affects the spine, one for the left arm, etc. Controls can be assigned to any number of sets.
Groups: Any number of set sliders can be organized into collapsable named groups. For example, you could create a group for each character in your scene.
Save with scene: Data for groups and sets is saved with your scene file. When you reload your scene and start the tweenMachine, it will read the existing data and rebuild the UI automatically.
Load/Save: Save data for all groups and sets to a text file, and load it into another scene.
Import: Import specific sets or groups from a saved data file.
Timeline ticks: Enable/disable ticks on the timeline for any set or group, so you can see where your poses are without having to select anything.
Stay tuned for more!
