2. Select one or more properties or property groups in the Timeline panel, and click the Brainstorm button
The variant compositions all play in the Brainstorm dialog box simultaneously. Controls for each variant are only visible when the pointer is
over it. Use the playback controls at the bottom of the Brainstorm dialog box to play, pause, or rewind the previews.
3. In the Brainstorm dialog box, do any of the following:
To get a better look at a variant, click its Maximize Tile
variants.
To show or hide the transparency grid, click the Toggle Transparency Grid
To mark a variant for inclusion in the next Brainstorm operation, click the Include In Next Brainstorm
To save a variant as a new composition in the current project, click the Save As New Composition
To increase the randomness or spread for the next generation, adjust the Randomness or Spread value at the bottom of the Brainstorm
dialog box. Make this number small for precision work; make it larger for experimentation and exploration.
4. (Optional) To create another generation of variants from the variants marked for inclusion in the next Brainstorm operation, click Brainstorm
at the bottom of the Brainstorm dialog box and return to step 2. If you click Brainstorm without marking any variants for inclusion, the
Brainstorm operation is repeated using the same input as the current generation.
If the Brainstorm operation uses Randomness, the variants marked for input into the next generation are included unchanged into the next
generation, and remain in their positions in the dialog box. If the Brainstorm operation uses Spread, only one variant is carried into the next
generation, and it appears in the center tile.
Repeat this cycle until you have found the variant that you want to save as the current composition.
You can move back or forward a generation by clicking the arrow buttons on either side of the Brainstorm button at the bottom of the
Brainstorm dialog box. If you move back a generation and then perform another Brainstorm operation, the later generations are lost.
Note: Press Esc to close the Brainstorm dialog box.
Note: If you use the Save As New Composition feature and the current composition contains expressions that refer to itself using the
comp("<name>") format, then the saved compositions' expressions will refer to the original composition, not each saved composition. If your
expression needs to rely on the settings in its own composition, use the thisComp object instead.
