Scenes & Outputs
Scenes
A scene is any TouchDesigner network: video, DMX, lasers, audio or data. It shows on the grid as a tile.
Adding Scenes
TODO (Jack): from Assets, from a .tox file, new empty network from a template.
What Runs When
Only scenes that are live, transitioning in, or toggled on are running. Every other scene is paused and its textures are unloaded, so a large show doesn't fill your GPU memory.
TODO (Jack): note the preload time (Settings > Performance) for timeline cues.
Output Groups
An output group plays one scene at a time and transitions between them.
Each group names the operator it takes from the live scene, out1 by default. What kind of operator it finds decides how the group transitions:
| Operator | Transition |
|---|---|
| TOP (video) | Crossfade |
| POP (points, lasers) | Blend between point sets |
| CHOP or DAT (data, DMX) | Switches at the start of the Go, never crossfades |
Note
DISPATCH doesn't layer scenes. For layered video, send to AAVJ.
Group Settings
Set these in the Outputs panel:
- Out op: the operator name to take from each scene (
out1by default). - Transition time: in seconds, 1 s by default. 0 is a cut.
- Resolution: 1920 × 1080 by default.
TODO (Jack): adding, colouring and removing groups. Screenshot of the Outputs panel.
Outputs
An output sends something from a group's live scene to a device. Each output names the operator it reads.
TODO (Jack): adding an output, and the output types (NDI, Syphon/Spout, video device, Touch Out, DMX, OSC, MIDI). Explain the send methods in user terms: in, chop, fixture, par.
Screen Output
TODO (Jack): sending a group to a display.
