Cesium for Unreal v1.27.1

This release includes support for Unreal Engine v5.0, v5.1, and v5.2 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

Fixes 🔧

• Fixed a shader compilation error introduced in v1.27.0 that prevented projects from opening in Unreal Engine 5.1 and 5.2.
• Fixed a debug assertion !IsGarbageCollecting() that could occur within ACesiumCreditSystem when flying to different sublevels.

Cesium for Unreal v1.27.0

This release includes support for Unreal Engine v5.0, v5.1, and v5.2 for Windows, Linux, macOS, Android, and iOS. Please select the appropriate ZIP for your version.

Additions 🎉

• Added support for Unreal Engine 5.2.
• Added support for running Cesium for Unreal in the Unreal Editor in Linux under UE 5.2. Previous versions supported Linux only as a packaging target.
• Added point cloud shading options to Cesium3DTileset, which allow point cloud tilesets to be rendered with attenuation based on geometric error.
• ACesium3DTileset now emits a warning if the "Enable World Bounds Checks" option is enabled. That option can make the camera fly toward the origin unexpectedly.
• Added new settings to the Cesium section of the Project Settings, allowing users to control how many requests to handle before pruning and also how many elements to keep in the cache after pruning.

Fixes 🔧

• Fixed a bug introduced in v1.26.0 that caused an error when attempting to save a sub-level containing Cesium objects.
• Removed degenerate triangles from the collision mesh created for 3D Tiles. This will avoid warnings and runtime pauses with some tilesets.
• Fixed a bug in CesiumGlTFFunction that caused the glTF and 3D Tiles "Ambient Occlusion" value to be 0.0 (instead of the expected 1.0) when the model does not specify an explicit occlusion texture. This could cause some extremely dark shadows.
• Fixed a bug that could cause a crash when using Cesium Actors with World Partitioning.

In addition to the above, this release updates cesium-native from v0.24.0 to v0.25.0. See the changelog for a complete list of changes in cesium-native.

• Added an option on Cesium3DTileset to ignore the KHR_materials_unlit extension entirely and use normal lighting and shadows.
• Added CreateNavCollision property to Cesium3DTileset. When enabled, CreateNavCollision is called on the static meshes created for tiles.

Fixes 🔧

• Fixed unexpected reflection on tilesets with KHR_materials_unlit extension when the sun is close to the horizon.
