Cesium for Unreal v2.8.0

This release includes support for Unreal Engine v5.2, v5.3, and v5.4 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

• Unreal Engine 5.2: CesiumForUnreal-52-v2.8.0.zip
• Unreal Engine 5.3: CesiumForUnreal-53-v2.8.0.zip
• Unreal Engine 5.4: CesiumForUnreal-54-v2.8.0.zip

Additions 🎉

• Added universal (Intel and Apple Silicon) binaries for Unreal Engine 5.2. Unreal Engine 5.3 and 5.4 already had universal binaries.
• Raster overlays now have bAllowAnyoneToDestroyMe set to true by default. This allows them to be dynamically removed and destroyed at runtime via the Blueprint Destroy Component function called from anywhere, including Level Blueprints. Previously, attempting to delete a raster overlay from outside the Actor would result in an error.

Fixes 🔧

• Fixed a bug introduced in the previous release that caused instanced tilesets to render incorrectly.
• Debug sections are no longer compressed on Linux and Android, improving compatibility.
• Fixed a bug where calling Refresh on a CesiumRasterOverlay would cause the overlay to appear on the Cesium3DTileset, even if inactive.

This release updates cesium-native from v0.38.0 to v0.39.0. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v2.7.1

This release includes support for Unreal Engine v5.2, v5.3, and v5.4 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

Fixes 🔧

• Improved collision and line tracing against tilesets by working around an overly-aggressive degenerate triangle check in the Chaos physics engine.
• Fixed a bug that could cause a bad_any_cast exception when trying to access glTF extensions on non-Windows platforms. This commonly popped up when loading tilesets with metadata.
• Fixed a bug that caused the GetInteger64 functions on CesiumMetadataValue, CesiumPropertyArray, and CesiumPropertyTableProperty to always return the default value on non-Windows platforms.
• Fixed issue with UCesiumGlobeAnchorComponent::GetEllipsoid that caused compilation errors on some machines.

Additions 🎉

• Cesium for Unreal now supports using non-WGS84 ellipsoids.
  • An CesiumEllipsoid asset may be specified in the Ellipsoid field of a CesiumGeoreference.
  • To create a CesiumEllipsoid asset, right-click in the Content Drawer and select "Data Asset" under "Miscellaneous." Choose "Cesium Ellipsoid" from the menu that appears.

Fixes 🔧

• Fixed two problems with CesiumCartographicRasterOverlay:
  • Small tiles would never be excluded, even with "Exclude Selected Tiles" enabled.
  • Pieces of tiles would sometimes not have the raster overlay correctly applied to them. When using with clipping, this would cause bits of tiles to randomly appear inside the clipping polygon.
• Removed an unnecessary alpha check when selecting translucent base materials.
• Fixed a crash caused by CesiumSunSky when no viewport is activated in the Editor.
• Fixed build issues in Unreal 5.4.2 relating to UStaticMesh and glm::toMat4.

• Improved DynamicPawn movement by interpolating to its intended speed. This provides smoother movement over areas with large height variation, e.g., when flying over buildings in a city.
• Added TileWidth and TileHeight properties to CesiumWebMapTileServiceRasterOverlay.

Fixes 🔧

• Fixed an issue with pixel dithering artifacts that could appear on tilesets.
• Fixed an issue where DynamicPawn could get stuck after interrupting a flight from UCesiumFlyToComponent.
• Fixed a bug where CesiumTileMapServiceRasterOverlay, CesiumWebMapServiceRasterOverlay, and CesiumWebMapTileServiceRasterOverlay would attempt to load empty URLs.
• Fixed a bug that caused some textures shared between multiple glTF primitives to be missing entirely.
• Fixed a bug that caused tilesets to fail to load with the "Experimental Occlusion Culling Feature" enabled.
• Fixed a problem that could cause linker errors when packaging a game using both Cesium for Unreal and the Pixel Streaming plugin in Unreal Engine 5.4.

In addition to the above, this release updates cesium-native from v0.35.0 to v0.36.0. See the changelog for a complete list of changes in cesium-native.

• Added support for Cesium ion servers in single user mode. Tokens are not required to stream assets from such servers.

Fixes 🔧

Additions 🎉

• Significantly reduced CPU memory used by glTF and raster overlay textures.
• Improved texture creation performance on non-D3D platforms.
• Added support for the KHR_texture_transform glTF extension - including rotation - for CesiumFeatureIdTexture and CesiumPropertyTextureProperty.

Fixes 🔧

• Metadata-related textures are now created in TEXTUREGROUP_8BitData instead of TEXTUREGROUP_World.

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

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 📣

• 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.
