Additions 🎉

• Added support for Web Map Tile Service (WMTS) with CesiumWebMapTileServiceRasterOverlay.
• Significantly reduced CPU memory usage by textures on non-Windows systems.
• Added support for the KHR_texture_transform glTF extension - including rotation - in baseColorTexture, metallicRoughnessTexture, emissiveTexture, normalTexture, and occlusionTexture. The transformation is now applied on the GPU via nodes in the Material, rather than on the CPU by directly modifying texture coordinates.

Fixes 🔧

• Fixed a bug in MLB_DitherFade that made glTF materials with an alphaMode of MASK incorrectly appear as fully opaque.
• Fixed a bug in CesiumFlyToComponent that could cause the position of the object to shift suddenly at the very end of the flight.
• Fixed a bug that caused textures created by Cesium for Unreal on D3D11 and D3D12 (only) to not be counted in the "Texture Memory Used" stat in the "Memory" stat group or in any counter in the "TextureGroup" stat group.
• Fixed a bug in CesiumGltfComponent that would cause a crash if the Ignore KHR_materials_unlit setting was enabled on a point cloud.
• Fixed a bug in CesiumActors that would cause the editor to crash when running in Standalone mode.
• Fixed several build warnings when packing in Unreal Engine 5.3.
• Readded backwards compatibility for feature textures from EXT_feature_metadata, which was mistakenly removed.
• Fixed a bug that caused nav mesh creation to be slow due to creating duplicate physics meshes.

In addition to the above, this release updates cesium-native from v0.31.0 to v0.32.0. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v2.2.0

Breaking Changes 📣

• Deprecated IonAssetEndpointUrl on Cesium3DTileset and CesiumIonRasterOverlay. Use the new CesiumIonServer property instead.

Additions 🎉

• Added support for multiple Cesium ion servers by creating CesiumIonServer data assets.

In addition to the above, this release updates cesium-native from v0.30.0 to v0.31.0. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v2.1.0

This release includes support for Unreal Engine v5.1, v5.2, and v5.3 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

Additions 🎉

• Added support for styling with property textures in EXT_structural_metadata.
• Significantly improved tile download performance by adding HttpThreadActiveFrameTimeInSeconds=0.001 to Engine.ini. This results in a major performance improvement for all tilesets, particularly Google Photorealistic 3D Tiles.
• Added HttpMaxConnectionsPerServer=40 to Engine.ini. By default, only 16 connections are allowed, which limits the performance when downloading tiles.

Fixes 🔧

• Fixed a bug in the "Select New Token" dialog that caused an error when trying to create a new token without being connected.
• Fixed a bug where an EditCondition was not parsed correctly and caused Output Log window errors.
• Removed query parameters from filepaths if present, as they are no longer ignored by Unreal. This fixes a bug where the URL would not load correctly in some cases.
• Fixed a Tile Excluder bug that computed incorrect tile bounds, making tiles invisible when moving the tileset in the sample scene.
• Fixed a bug where viewports could appear wider than configured in the Dynamic Pawn's Camera Field of View. Noticed in Unreal Engine v5.3 when in Play-In-Editor mode, or a packaged game. In extreme cases, tiles would be missing near the edges of the view.

In addition to the above, this release updates cesium-native from v0.29.0 to v0.30.0. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v2.0.0

This release includes support for Unreal Engine v5.1, v5.2, and v5.3 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

Breaking Changes 📣

• Removed FCesiumIntegerColor, FCesiumFloatColor, UCesiumFeatureTexturePropertyBlueprintLibrary::GetIntegerColorFromTextureCoordinates and UCesiumFeatureTexturePropertyBlueprintLibrary::GetFloatColorFromTextureCoordinates. Check out the upgrade guide for how retrieve metadata from property textures with the new API.
• Renamed GetTextureCoordinateIndex to GetUnrealUVChannel in both UCesiumFeatureIdTextureBlueprintLibrary and UCesiumPropertyTexturePropertyBlueprintLibrary. Contrary to what the documentation claimed, this function retrieved the index of the texture coordinate set in the Unreal static mesh, which is not necessarily equal to the texture coordinate set index in the glTF primitive. For the latter value, use GetGltfTextureCoordinateSetIndex instead.
• Removed the old "exclusion zones" feature, which has been deprecated since v1.11.0. Use CesiumCartographicPolygon or CesiumTileExcluder instead.

Additions 🎉

• Added new functions to UCesiumPropertyTexturePropertyBlueprintLibrary to retrieve detailed property information and get the values of the property as a certain type. Check out the upgrade guide for how retrieve metadata from property textures with the new API.
• Added UCesiumMetadataPickingBlueprintLibrary::FindUVFromHit, which computes the UV coordinates from a line trace hit without requiring "Support UV Hit Info" to be enabled. This can used to retrieve more accurate feature IDs or metadata values by sampling at an intermediary point on the face.
• Added GetPropertyTableValuesFromHit and GetPropertyTextureValuesFromHit to UCesiumMetadataPickingBlueprintLibrary to retrieve the respective metadata from a line trace hit. For both functions, the target to sample is specified by index.
• Added UCesiumFeatureIdSetBlueprintLibrary::GetFeatureIDFromHit to retrieve the feature ID from a line trace hit on a primitive containing the feature ID set. This returns more accurate values for feature ID textures than GetFeatureIDForVertex.
• Added UCesiumPrimitiveFeaturesBlueprintLibrary::GetFeatureIDFromHit to retrieve the feature ID from a line trace hit on a primitive, where the desired feature ID set is specified by index. For feature ID textures, this returns more accurate values than GetFeatureIDFromFace.
• Added UCesiumFeatureIdTextureBlueprintLibrary::GetFeatureIDForUV, which samples a feature ID texture with FVector2D UV coordinates.
• Added GetGltfTextureCoordinateSetIndex to UCesiumFeatureIdTextureBlueprintLibrary and UCesiumPropertyTexturePropertyBlueprintLibrary to avoid ambiguity with GetUnrealUVChannel.
• Added UCesiumMetadataValueBlueprintLibrary::GetValuesAsStrings to convert a map of FCesiumMetadataValues to their string representations.
• Added support for file:/// URLs across all platforms and Unreal Engine versions.
• Added "Create Sub Level Here" button on CesiumGeoreference.
• Added "Place Georeference Origin Here" button to CesiumSubLevelComponent.
• Added "Google Photorealistic 3D Tiles" to the Quick Add panel.

Fixes 🔧

• Fixed a bug that could cause tiles in a Cesium3DTileset to have an incorrect transformation.
• Fixed a crash that occurred when a LevelSequenceActor in the level did not have a LevelSequencePlayer assigned.
• Fixed a bug that would spam Georeference-related messages to the log when editing a globe anchor component that is not embedded in a world. For example, when editing a Blueprint asset with a globe anchor.
• Fixed several problems that could cause tilesets in sub-levels to be misaligned with the rest of the globe.

Deprecated ⌛

• UCesiumFeatureIdTextureBlueprintLibrary::GetFeatureIDForTextureCoordinates has been deprecated. Use UCesiumFeatureIdTextureBlueprintLibrary::GetFeatureIDForUV instead.
• UCesiumPropertyTexturePropertyBlueprintLibrary::GetSwizzle and UCesiumPropertyTexturePropertyBlueprintLibrary::GetComponentCount have been deprecated, since they are no longer necessary to handle property texture property values in the plugin. Use UCesiumPropertyTexturePropertyBlueprintLibrary::GetChannels instead.
• UCesiumMetadataPickingBlueprintLibrary::GetMetadataValuesForFace has been deprecated. Use UCesiumMetadataPickingBlueprintLibrary::GetPropertyTableValuesForHit instead.
• UCesiumMetadataPickingBlueprintLibrary::GetMetadataValuesForFaceAsStrings has been deprecated. Use UCesiumMetadataValueBlueprintLibrary::GetValuesAsStrings to convert the output of UCesiumMetadataPickingBlueprintLibrary::GetPropertyTableValuesForHit instead.
• UCesiumPropertyTableBlueprintLibrary::GetMetadataValuesForFeatureAsStrings has been deprecated. Use UCesiumMetadataValueBlueprintLibrary::GetValuesAsStrings to convert the output of UCesiumPropertyTableBlueprintLibrary::GetMetadataValuesForFeature instead.

In addition to the above, this release updates cesium-native from v0.28.1 to v0.29.0. See the changelog for a complete list of changes in cesium-native.
