Layer comps and presets

A scene often needs to exist in more than one state: a day version and a night version, a clothed pass and an alternate, a working view full of guides and a clean view for readers. Comps (layer comps) let you save which rows are visible as a named preset and snap back to it in one click. This tutorial covers saving, applying, and deleting comps, the situations they save you in, and the real limits of the feature.

1What a layer comp is

A comp, short for layer comp, is a saved snapshot of which rows are showing and which are hidden. It does not touch your keyframes, your art, or your timing; it only remembers visibility. It is a saved on/off pattern for your rows: this row on, that row off, saved under a name you can return to instantly. One scene, many looks, no duplication.

A comp saves visibility only. Your animation, art, and timing are untouched. That is exactly why comps are safe to make and throw away freely.
Pro note
A comp is just a saved pattern of which rows are on and off. Nothing destructive, nothing scary.

2Why visibility presets matter

The moment a scene has alternates, manually toggling rows on and off gets tedious and error-prone; forget one row and your night scene has a daytime sky. A saved comp toggles the whole pattern at once, correctly, every time. It turns a fiddly, mistake-prone chore into a single click, which matters most when you are switching back and forth to compare two versions.

The value of a comp grows with your row count. On a scene with a handful of rows it is convenient; on a busy scene it is the difference between seconds and minutes.
Pro note
Flipping ten rows by hand every time you compare versions? That way lies madness. Save the pattern once and click it forever.

3Set your visibility first

A comp captures whatever is showing right now, so get the scene looking exactly how you want the preset to look before you save. Toggle each row's visibility until only the rows for this version are on, guide and reference rows hidden if they should not be part of it. Take a moment to check the stage matches the look you intend. What you see is precisely what the comp will remember.

A comp saves exactly what is visible. If a stray guide row is showing when you save, that guide becomes part of the comp. Tidy the view first.
Pro note
The comp snaps whatever is on screen. So set the scene up properly first, then save. Rubbish in, rubbish saved.

4Save a named comp

Open the Comps panel and save the current visibility as a new comp, giving it a clear name like Day, Night, or Clean. The panel records exactly which rows are on and off at that moment and stores it under your name. That name is now a one-click shortcut back to this exact look, however much you fiddle with visibility afterward.

Name comps for the look, not the mechanism. Night and Outfit B tell you what you get; Comp 1 and Comp 2 tell you nothing three weeks later.
Pro note
Set the look, hit save, give it a name you will actually recognise later. Day, Night, Clean. Done and dusted.

5Apply a comp in one click

This is the payoff. Click a saved comp in the Comps panel and the scene's row visibility snaps to that saved pattern instantly, every row set exactly as it was when you saved. Switch between two comps and you flip between two whole versions of the scene with a click each, perfect for comparing a day and a night pass side by side without touching a single row by hand.

Applying a comp only changes what is visible. It never alters your animation, so bounce between comps as often as you like while you compare.
Pro note
Click Day, click Night, click Day again. Whole versions of your scene flip in one click each.

6Delete a comp

When a preset is no longer useful, remove it. In the Comps panel, delete the comp you no longer need and it is gone from the list. Deleting a comp only forgets that saved visibility pattern; it does not hide or remove any rows, and your current view stays exactly as it is. It is pure housekeeping, so prune freely to keep the list readable.

Deleting a comp never touches your rows or art, it just drops the saved pattern. There is nothing risky about tidying your comp list.
Pro note
Old comp cluttering the list? Delete it. Your rows do not budge, you just lose a preset you were not using anyway.

7Use case: alternate versions

The classic use is holding two versions of a scene in one project. Build a fully clothed pass on one set of rows and an alternate pass on another, then save each visibility state as its own comp. Now a single click swaps the entire look. You keep both versions in the same file instead of maintaining two separate scenes that drift out of sync.

One scene with two comps beats two copies of a scene. Fix the shared animation once and both versions get the fix, because they are the same file.
Pro note
Two versions, one scene, two comps. No more keeping two near-identical files in step by hand. Let the comp do the swapping.

8Use case: day and night

Comps make lighting variants painless. Put your daytime sky, warm light, and short shadows on one group of rows, and a night sky, cool light, and lit windows on another. Save a Day comp and a Night comp, and the same street can flip from noon to midnight in one click. It is the tidiest way to reuse a whole set for two times of day without rebuilding it.

Share the parts that do not change, buildings, characters, props, across both comps, and only vary the sky and lighting rows. Less to maintain, and the two versions stay perfectly aligned.
Pro note
Same street, noon to midnight, one click. Just swap the sky and light rows between comps and let everything else stay put.

9Use case: hide guides before you publish

While you work, your scene is full of helpers: reference rows, tracing images, blocking guides, notes to yourself. None of that belongs in what readers see. Save a Clean comp with every guide and reference row hidden and only the finished artwork showing, then apply it right before you Publish. One click guarantees no stray guide sneaks into the version your readers watch.

Make applying your Clean comp the last thing you do before Publish. It is a reliable pre-flight check against a guide row slipping into the final.
Pro note
One Clean comp, applied right before you publish, and no rogue guide row ever ends up in front of your readers. Belt and braces.

10Comps are non-destructive

It bears repeating because it changes how boldly you use the feature: comps only ever touch visibility. Hiding a row with a comp is nothing like deleting it, the row, its art, and its keyframes are all still there, just not shown. This is why comps are the safe way to try a version. Nothing you do with them can lose work, so experiment as freely as you like.

Because comps are non-destructive, they are also a safe undo net. Save your current look as a comp before a risky experiment and you can always click back to it.
Pro note
Hidden is not deleted. A comp only changes what is shown, never removes anything. That is why you can experiment freely.

11Comps and your rigs

Comps work alongside rigged characters and live instances. A comp simply remembers whether a character's row is shown, so you can hide an entire instance in one comp and reveal it in another, staging who is present in a scene without deleting anyone. Combine that with alternate prop or wardrobe rows and a single scene can present several quite different casts and looks.

Use comps to audition staging: which characters are on stage, which props are out. Nobody is removed, so you can bring them back with the other comp instantly.
Pro note
Hide a whole character in one comp, bring them back in another. Great for auditioning who is actually in the shot.

12Name comps carefully

Because a comp keeps the name you give it at save time, spend a second on that name. Descriptive, look-based names, Day, Night, Clean, Outfit B, pay off every time you scan the list. A vague name is a small tax you pay on every future click. Getting the name right up front is the cheapest way to keep the panel usable as your project grows.

There is no rename after saving, so the name you choose is the name you keep. If a name turns out wrong, the fix is to save a fresh comp and delete the old one.
Pro note
Name it right the first time, because it sticks. A good name now saves you squinting at Comp 3 in a month's time.

13The limits to know

Three limits to know so nothing surprises you. There is no rename, to relabel a comp, save a new one with the right name and delete the old. There is no expose-on-timeline, a comp is a manual click, not something you key to switch mid-scene, so animate visibility on the rows themselves if you need it to change during playback. And there is no export-split, the studio will not publish each comp as its own output automatically, so apply a comp, publish, then apply the next and publish again.

The export-split workaround is simple: comps plus Publish, one version at a time. Apply, publish, switch comp, publish. Two clean outputs, a couple of extra clicks.
Pro note
No rename, no keying a comp on the timeline, no auto-splitting on export. Small gaps, easy workarounds, and now no nasty shocks.

14Good comp hygiene

Comps reward a little discipline. Keep a small, well-named set, Day, Night, Clean, and the alternates you actually use, rather than a graveyard of Comp 4 through Comp 12. Set each version's visibility carefully before you save it, always apply your Clean comp before you Publish, and delete presets the moment they stop earning their place. Kept tidy, the Comps panel is one of the quiet time-savers of the whole studio.

Keep the comp list short and clear. A handful of clear presets you trust beats a long list you have to decode.
Pro note
A few clear comps you trust, tidied often, Clean applied before Publish. That is all there is to it. You are set.

Comp questions

Only which rows are visible and which are hidden at the moment you save it. It does not store keyframes, art, or timing. Applying a comp restores that visibility pattern and changes nothing else about your scene.

Save each version's visibility as its own comp, for example Day and Night, then click a comp in the Comps panel to apply it. The scene's rows snap to that pattern instantly, so you flip between whole versions with one click each.

No. Comps are non-destructive. A hidden row keeps its art and its keyframes and simply is not shown. That is why comps are the safe way to try alternate versions without any risk of losing work.

Save a Clean comp with every guide and reference row hidden and only the finished artwork visible, then apply it right before you Publish. One click ensures no stray guide row slips into the version your readers watch.

Not currently. There is no rename. To relabel a comp, set the same visibility, save a new comp with the correct name, and delete the old one. Because of this, it pays to name comps clearly the first time.

No. There is no expose-on-timeline, so a comp is a manual click rather than something you key mid-scene. If you need visibility to change during playback, animate it on the individual rows themselves instead of relying on a comp.

No. There is no export-split, so the studio will not publish every comp as its own output automatically. Apply one comp and Publish, then apply the next comp and Publish again. It is a couple of extra clicks for two clean outputs.

No. Deleting a comp only forgets that saved visibility pattern. Your rows, their art, and their keyframes are untouched, and your current view stays exactly as it is. Prune the comp list freely to keep it readable.

One scene, every look

You can now save row visibility as named comps, flip between day and night or alternate passes in a click, hide your guides before you publish, and work around the few edges cleanly. That is the finishing kit, and it is the last stop on the animation course. Head back to the index and pick what to learn next.
