v2.24.1 - 2026-03-02

Fixes 🔧

• Fixed an invalid Cesium ion test token.

v2.24.0 - 2026-03-02

Breaking Changes 📣

• Deprecated AddCamera, RemoveCamera, UpdateCamera, and GetCameras on ACesiumCameraManager. Instead, use the new AdditionalCameras array to directly add or remove cameras.
• Removed Cesium3DTileset::getFeaturesMetadataDescription. This can be directly retrieved from its attached UCesiumFeaturesMetadataComponent instead.

Additions 🎉

• Added support for loading tilesets with the KHR_gaussian_splatting extension.
• Added support for styling with tileset statistics on UCesiumFeaturesMetadataComponent.
• Added UCesiumPropertyArrayBlueprintLibrary::ToString to print the contents of a FCesiumPropertyArray as a string.
• Added DetectTransformChanges to UCesiumGlobeAnchorComponent to toggle whether the globe anchor should update itself after changes in its Actor's transform.
• Added UsePlayerCameras, UseEditorCameras, and UseSceneCapturesInLevel to ACesiumCameraManager to toggle the automatic detection of cameras in the level for tile selection.
• Added ACesiumCameraManager::SceneCaptures for more explicit control over which ASceneCapture2Ds are used for tile selection.
• Added the option for FCesiumCamera to use parameters from a given UCameraComponent assigned through C++ or Blueprints.

Fixes 🔧

• Added a missing includes in CesiumCartographicPolygon.cpp and CesiumMetadataValue.h, introduced in v2.23.0.
• Build now uses the tinyxml2 library from Unreal's SDK on Linux and Windows if it is available. This eliminate a source of conflicts with other plugins that also use tinyxml2.

In addition to the above, this release updates cesium-native from v0.57.0 to v0.58.0. See the changelog for a complete list of changes in cesium-native.

• Added ACesiumCartographicPolygon::SetPolygonPoints to shape a polygon spline from a list of points in cartographic or Earth-Centered, Earth-Fixed space.
• Re-enabled ACesium3DTileset::EnableWaterMask for macOS devices.

Fixes 🔧

• Fixed an access violation that could occur if ACesium3DTileset::RefreshTileset was invoked in a callback for asynchronous actions.

Cesium for Unreal v2.22.0

This release includes support for Unreal Engine v5.5, v5.6, and v5.7 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

• Unreal Engine 5.5: CesiumForUnreal-55-v2.22.0.zip
• Unreal Engine 5.6: CesiumForUnreal-56-v2.22.0.zip
• Unreal Engine 5.7: CesiumForUnreal-57-v2.22.0.zip

Breaking Changes 📣

• Removed support for Unreal Engine 5.4. Unreal Engine 5.5 or later is now required.

Additions 🎉

• Replaced the "Auto Fill" button on UCesiumFeaturesMetadataComponent with "Add Properties". This allows metadata properties and feature ID sets to be selectively added to the component, rather than adding them all in bulk.
• Added EnableDoubleSidedCollisions to ACesium3DTileset to allow intersections and collisions with geometry to also work when hitting "back" faces.
• Added an optional glTF model post-processing stage after the tile loading step, before the tile can be displayed.
• Added support for refreshing Cesium ion login tokens after they expire and the refresh token is still valid.

Fixes 🔧

• Fixed a material generation bug on UCesiumFeaturesMetadataComponent where user-made connections to If nodes were not preserved.
• Removed bHasKhrTextureTransform from FCesiumFeatureIdSetDescription and FCesiumPropertyTexturePropertyDescription. This will not break any existing materials generated by UCesiumFeaturesMetadataComponent; instead, it will always generate additional nodes to handle the KHR_texture_transform extension if present.
• Fixed deprecation warnings when compiling with Unreal Engine 5.5+ by replacing deprecated GetInputsView() calls with FExpressionInputIterator.
• Fixed bugs that prevented instanced meshes from working with UCesiumPrimitiveFeaturesBlueprintLibrary::GetPrimitiveFeatures, UCesiumModelMetadataBlueprintLibrary::GetModelMetadata, and UCesiumPrimitiveMetadataBlueprintLibrary::GetPrimitiveMetadata.

In addition to the above, this release updates cesium-native from v0.55.0 to v0.56.0. See the changelog for a complete list of changes in cesium-native.

Additions 🎉

• Added CesiumAzureMapsRasterOverlay.
• Added the interface ICesium3DTilesetLifecycleEventReceiver: when an implementation is registered on a tileset (with ACesium3DTileset::SetLifecycleEventReceiver), its functions will be called at various points in a tile's lifecycle, like when a mesh component is created, when a material is instanced, when the tile changes visibility, when it is unloaded, etc.

Fixes 🔧

• Fixed a bug where CesiumCreditSystem would not filter out empty credits, resulting in duplicate on-screen delimiters.
• Fixed a problem where multi-selecting UCesiumGlobeAnchorComponent could cause the selected components to teleport to 0 degrees longitude and 0 degrees latitude. Now, the geospatial position and orientation fields are hidden while multi-selecting.
