Settings are configuration values that control CE.SDK editor behavior without modifying scene content. They are accessed via key paths (e.g., page/title/show) and support multiple types including Bool, Int, Float, String, Color, and Enum. Use settings to customize visual appearance, interaction behavior, resource paths, and feature toggles.
When to Change Settings#
Settings can be changed at any time after engine initialization, but they fall into two categories based on when they should be modified.
Initialization-Only Settings#
Some settings should only be set once during or immediately after engine initialization. Changing them later may have no effect or cause unexpected behavior:
license- The license key validates on startup; changing it later has no effectbasePath- The base URL for resolving assets; should be set before loading any resourcesdefaultFontFileUri/defaultEmojiFontFileUri- Default fonts used when no font is specified; should be set earlymaxImageSize- Memory limit for images; changing mid-session won’t affect already-loaded images
Runtime Settings#
Most settings can be changed at any time and take effect immediately:
- Visual appearance:
highlightColor,snappingGuideColor,cropOverlayColor,page/title/color - Interaction behavior:
doubleClickToCropEnabled,doubleClickSelectionMode,touch/*,mouse/* - Control gizmos:
controlGizmo/resizeHandlesVisibility,controlGizmo/rotateHandlesVisibility - Page display:
page/title/show,page/dimOutOfPageAreas,page/title/separator - Feature toggles:
blockAnimations/enabled,useSystemFontFallback,forceSystemEmojis - Snapping thresholds:
positionSnappingThreshold,rotationSnappingThreshold
These runtime settings are commonly used to adapt the editor UI to different modes, user preferences, or workflow states.
Using the Settings API#
Discover Available Settings#
Use findAllSettings() to get a list of all available settings:
const allSettings = engine.editor.findAllSettings();Read and Write Settings#
Use getSetting() and setSetting() to read and write settings. The API automatically handles the correct type based on the setting key:
// Boolean settingsengine.editor.setSetting('doubleClickToCropEnabled', true);const cropEnabled = engine.editor.getSetting('doubleClickToCropEnabled');
// Number settingsengine.editor.setSetting('maxImageSize', 4096);engine.editor.setSetting('positionSnappingThreshold', 2.0);
// String settingsengine.editor.setSetting('page/title/separator', ' | ');
// Color settingsengine.editor.setSetting('highlightColor', { r: 1, g: 0, b: 1, a: 1 });
// Enum settingsengine.editor.setSetting('doubleClickSelectionMode', 'Direct');const enumOptions = engine.editor.getSettingEnumOptions( 'doubleClickSelectionMode');Subscribe to Settings Changes#
React to settings changes using onSettingsChanged():
const unsubscribe = engine.editor.onSettingsChanged(() => { console.log('Editor settings have changed');});
// Later, to stop listening:unsubscribe();Role Management#
Roles apply predefined defaults for scopes and settings:
// Get current roleconst currentRole = engine.editor.getRole();
// Set role and apply role-dependent defaultsengine.editor.setRole('Adopter');
// React to role changesconst unsubscribe = engine.editor.onRoleChanged((role) => { console.log('Role changed to:', role);});Available Settings#

Editor Settings
This section describes the all available editor settings.
| Property | Type | Default | Description |
|---|---|---|---|
archival/bundleOnlyUsedFontVariants | Bool | false | When enabled, saveSceneToArchive and saveBlocksToArchive bundle only the font variants actually referenced by text blocks. When disabled (default), every variant of each referenced typeface is bundled so the loaded scene can freely switch fonts without re-fetching assets. |
basePath | String | "some-base-path" | The root directory for resolving relative paths and bundle:// URIs (on platforms that don’t offer bundles.). Also used as the base URL for loading font fallback files and the default emoji font (when self-hosting assets). |
blockAnimations/enabled | Bool | true | Whether animations should be enabled or not. |
borderOutlineColor | Color | {"r":0,"g":0,"b":0,"a":1} | The border outline color. |
camera/clamping/overshootMode | Enum | "Reverse" | Controls what happens when the clamp area is smaller than the viewport. Center: the clamp area is centered in the viewport. Reverse: the clamp area can move inside the viewport until it hits the edges., Possible values: "Center", "Reverse" |
clampThumbnailTextureSizes | Bool | true | Whether to clamp thumbnail texture sizes to reduce memory usage. |
clearColor | Color | {"r":0,"g":0,"b":0,"a":0} | The color with which the render target is cleared before scenes get rendered. Only used while renderMode == RenderMode::Preview. |
colorMaskingSettings/maskColor | Color | {"r":1,"g":1,"b":1,"a":1} | The current mask color. Defaults to white, which disabled all masking. |
controlGizmo/blockScaleDownLimit | Float | 8 | Scale-down limit for blocks in screen pixels when scaling them with the gizmos or with touch gestures. The limit is ensured to be at least 0.1 to prevent scaling to size zero. |
controlGizmo/dynamicMoveHandleVisibility | Bool | true | Deprecated: prefer controlGizmo/moveHandleVisibility. Whether the move handle visibility is dynamic based on block size. When enabled (default), the move handle only appears when the block is small enough that resize handles would cover the interaction area. Setting it to false is equivalent to moveHandleVisibility: 'always'. |
controlGizmo/moveHandleVisibility | Enum | "auto" | Controls when the standalone move handle is shown for a selected block. 'auto' (default) shows it only when the block is too small for the resize handles to be usable; 'always' shows it regardless of block size and also while the block is in text edit (input) mode, so it can be repositioned while typing; 'never' hides it. 'always' does not apply in crop edit mode, which has its own handles. Supersedes the deprecated controlGizmo/showMoveHandles and controlGizmo/dynamicMoveHandleVisibility booleans., Possible values: "auto", "always", "never" |
controlGizmo/resizeHandlesVisibility | Enum | "auto" | Controls when the non-proportional edge (resize) handles are shown. 'auto' (default) shows them in transform edits; 'always' also shows them while the block is in text edit (input) mode; 'never' hides them. 'always' does not apply in crop edit mode, which has its own handles. Supersedes the deprecated controlGizmo/showResizeHandles boolean., Possible values: "auto", "always", "never" |
controlGizmo/rotateHandlesVisibility | Enum | "auto" | Controls when the rotation handle is shown. 'auto' (default) shows it in transform edits; 'always' also shows it while the block is in text edit (input) mode; 'never' hides it. 'always' does not apply in crop edit mode, which has its own handles. Supersedes the deprecated controlGizmo/showRotateHandles boolean., Possible values: "auto", "always", "never" |
controlGizmo/scaleHandlesVisibility | Enum | "auto" | Controls when the proportional corner (scale) handles are shown. 'auto' (default) shows them in transform edits; 'always' also shows them while the block is in text edit (input) mode; 'never' hides them. 'always' does not apply in crop edit mode, which has its own handles. Supersedes the deprecated controlGizmo/showScaleHandles boolean., Possible values: "auto", "always", "never" |
controlGizmo/showCropHandles | Bool | true | Whether or not to show the handles to adjust the crop area during crop mode. |
controlGizmo/showCropScaleHandles | Bool | true | Whether or not to display the outer handles that scale the full image during crop. |
controlGizmo/showMoveHandles | Bool | true | Deprecated: prefer controlGizmo/moveHandleVisibility. Master on/off switch for the move handle; setting it to false is equivalent to moveHandleVisibility: 'never'. |
controlGizmo/showResizeHandles | Bool | true | Deprecated: prefer controlGizmo/resizeHandlesVisibility. Whether or not to display the non-proportional resize handles (edge handles). Setting it to false is equivalent to resizeHandlesVisibility: 'never'. |
controlGizmo/showRotateHandles | Bool | true | Deprecated: prefer controlGizmo/rotateHandlesVisibility. Whether or not to show the rotation handle. Setting it to false is equivalent to rotateHandlesVisibility: 'never'. |
controlGizmo/showScaleHandles | Bool | true | Deprecated: prefer controlGizmo/scaleHandlesVisibility. Whether or not to display the proportional scale handles (corner handles). Setting it to false is equivalent to scaleHandlesVisibility: 'never'. |
