Persona

Settings is the last row in the Control Panel's left column, and it holds everything that is the same whichever scene is on: interface language, theme, the tray icon, rendering performance, and the Plugin API. Updates and the About dialog live in the panel header

Shortcuts are not here but on a row of their own, just below Tracking — see Shortcuts

The page is four collapsible sections — General, Performance, Storage and Plugin API — and each remembers whether you left it open. Storage and Plugin API start collapsed

The stage window's size, along with Stream Mode, Show FPS Counter and Selection Outline, is not here but under the Window section of the Stage row

General

Language

Persona ships four interface languages, each listed in the picker under its own name

System reads the language tag the operating system reports. Chinese resolves to 繁體中文 for the Traditional variants — zh-Hant, zh-TW, zh-HK and zh-MO, matched by region because most systems report those without a Hant subtag — and to 简体中文 otherwise. Japanese matches its own. Everything else falls back to English

The change applies immediately across the whole interface, including the tray menu, with no restart

Theme

The colour scheme for the control panel, its dialogs and its menus: System, Light, or Dark. It follows the system by default and switches with the operating system's appearance

It only touches the interface. The stage is unaffected — what renders there comes from the background, the lights and the effects, independently of the interface theme

Keep Panel on Top

Floats the Control Panel above the stage and every other window, so you can watch it while clicking into the stage to arrange a scene. Off by default. It targets the panel, not the stage — see Window Behaviour

Menu Bar Icon

The switch is labelled Show Tray Icon on Windows and Show Menu Bar Icon on macOS and Linux, matching what each platform calls it

On macOS the icon is a monochrome template image, so it adapts to the menu bar like a native application — dark on a light bar, light on a dark one

Turning it off gives you a cleaner menu bar and costs you no access. The switch itself then spells out how to summon the Control Panel without it: ⌘ + , or the app menu on macOS, and on Windows and Linux, clicking the stage and pressing Ctrl + ,

Send Bug Reports

On by default. Anonymous crash and error reports help diagnose application problems. Reports include diagnostic information and recent app events, which may contain webpage layer URLs; native crash reports may also include a memory dump

Turning it off means the reporter is never initialised at all. The setting is read at launch, so changing it raises the Restart to fully apply prompt

Performance

Background Rendering

Persona now keeps background rendering on all the time. The operating system normally throttles a window that is hidden or covered, which stops the avatar animating — the last thing you want when OBS is capturing the window and you have tabbed away from it. Persona keeps the render loop running and asks the system not to suspend the application

The former switch is gone; there is nothing to configure. This does not stop the display from sleeping according to the system settings

Limit Frame Rate

Caps both render loops — the 2D stage and the 3D one, so a VRM scene and its effects are throttled along with everything else. Useful on a high refresh rate display, where a frame cap can reduce unnecessary GPU usage

Effects Quality

Sets how the 3D visual effects and the selection outline antialias, at High, Medium or Low. Lower is faster

It costs nothing in a scene with every effect off

Render Scale

How large a canvas the 3D stage draws into, at 100%, 85%, 75%, 66% or 50%, defaulting to 100%. It multiplies the device pixel ratio, so the pixel dimensions also depend on your display scaling

Lowering the render scale reduces the pixels processed throughout the effects chain, which can improve frame rate. The tradeoff is a softer image, especially around avatar edges and fine patterns

It only touches the 3D stage. 2D objects, and Live2D on the legacy engine, are drawn on a separate 2D canvas and are unaffected

Use Legacy WebGL Engine

Off by default. Turning it on moves Live2D from the default WebGPU engine back to the legacy WebGL engine, outside the 3D stage and its effects chain. It is lighter on resources for one simple model; switching reloads the scene

With it on, a Live2D-only scene can no longer add effects, and the Look section disappears. See Rendering Engines

Storage

Settings, scenes and API keys all live in one folder, ~/.laplace/persona. Open Folder reveals it in your file manager

Backing up, moving and restoring are all copies or replacements of that folder. Quit Persona first — while it runs it writes its own state back, over whatever you just put there

Open Logs reveals logs/ in that same folder. Persona always writes errors and warnings to main.log, with nothing to switch on: the file never leaves your computer, and Send Bug Reports is the only path over the network. Attach it when you report a problem. At 2 MB it rotates into a timestamped archive, and the five newest are kept

Upgrading from an earlier version moves settings out of the application data directory on first launch, leaving the old files where they are

Plugin API

The rest of Settings enables and configures the local WebSocket server other applications drive — the port, local network access, API keys, plugin folders and the list of connected clients. It has its own page: Plugin API

First Run

The first time you open Persona, a three-step walkthrough sits over the Control Panel: a welcome, the Live2D renderer (WebGPU or WebGL (Legacy)), and whether to Send Bug Reports — Learn more about privacy below that step opens Privacy and Security in your system browser. Finish writes both choices to your settings, along with the mark that says you have been through it

Only that first run refuses Esc and a click outside, so it is seen exactly once. Onboarding… on the panel header's menu opens it again whenever you like; that time it is an ordinary dialog you can dismiss, and every opening reads the settings as they stand

An install upgraded from an earlier version sees it once too — the mark defaults to off and is never pre-set for a settings file that predates it

About

The panel header's menu also carries Documentation, Web Console and Onboarding… — the first two open these docs and the web console in your system browser, the last reopens the first-run walkthrough

About LAPLACE Persona — in the panel header's menu, the tray menu, and the application menu on macOS — shows the version and the third-party notices for everything bundled in the build: the Live2D Cubism Core and sample models, the VRM avatars, the VRM animation and idle animation packs with their required credits, and the interface font

Updates

The version number sits in the top-right of the panel header. It is also the update control

Persona checks once, quietly, about ten seconds after launch, and again whenever you click the version row. Installer downloads begin only after you confirm an update

The Update Flow

1. Check — click the version row. If you are current, a toast says so. If not, the update dialog opens
2. Choose — Update starts the download, Later dismisses, Skip This Version silences automatic checks for that version. A skipped version still appears if you click the version row yourself
3. Download — progress shows in the dialog. Persona stays usable, and closing the dialog does not stop the download
4. Install — Relaunch Now applies it immediately. Otherwise it installs the next time you quit

Persona initiates two types of outbound requests: update checks, and crash reports while Send Bug Reports is on. Checks go to downloads.vrp.moe and carry no identifying information beyond what any file download involves. That switch turns off bug reports; the current installer has no setting to disable update checks, so blocking the host is the only way to prevent them
