Preview Settings

A tab that gathers the options that affect only the editor preview — preview render quality, the onion-skin overlay, and the frame/node render caches. None of these settings are part of the scene, so they do not change the encoded output.

Tab characteristics​

  • Open by default: No
  • Allow multiple instances: No

How to open​

Open it from the menu bar via View → Tools → Preview Settings.

Preview render quality​

Selects the resolution at which the editor renders the preview, trading image quality for speed. Lowering it makes playback and scrubbing smoother on heavy scenes.

  • Full — render at the project resolution (output scale 1.0).
  • Half (1/2) — render at half resolution (0.5).
  • Quarter (1/4) — render at quarter resolution (0.25).
  • Fit to previewer — scale the frame to fit the on-screen previewer, capped at full resolution.

This setting cannot be changed during playback, and it is not saved with the project. Thanks to the resolution-independent rendering pipeline, lowering the preview quality keeps vector shapes, text, and most effects sharp at the reduced size rather than simply pixelating the result.

Onion skin​

Overlays neighboring frames as translucent ghosts so you can see motion across frames — useful for hand-drawn animation and timing. Toggle it from this tab or with the Alt + O shortcut.

  • Onion skin — master switch (off by default).
  • Previous frames — how many frames before the current one to overlay (default 1).
  • Next frames — how many frames after the current one to overlay (default 0).
  • Previous opacity — opacity of the previous-frame ghosts (default 0.35).
  • Next opacity — opacity of the next-frame ghosts (default 0.35).

Frame cache / Node cache​

These two sections enable and tune the editor's render caches. See Render cache for what each cache stores and how to size it.
