Cesium Releases in June 2023

In May we announced support for Esri ArcGIS location services in CesiumJS and our partnership with Google Maps Platform to render Photorealistic 3D Tiles. Among the many possibilities opened up by these collaborations is a demo app showing travel time using CesiumJS, Esri, and Photorealistic 3D Tiles. (Try it and tell us what you think.) We also shared the first four recipients of Cesium Ecosystem Grants, who are committed to opening and expanding the 3D geospatial ecosystem.

Cesium for Unreal 1.27.0 Release

Cesium for Unreal v1.27.0 is now available. This release includes support for Unreal Engine 5.2. Plus, in UE 5.2, Cesium for Unreal can now be used inside the Unreal Editor on Linux, and it has native support for Apple silicon (M1, M2) processors on macOS.

Other changes in this release include:

Added point cloud shading options to Cesium3DTileset, which allow point cloud tilesets to be rendered with attenuation based on geometric error.
GZipped files are now automatically decompressed when loaded, which is especially helpful for compressed tilesets loaded from the local file system.
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.
Improved visual quality of shadows by correctly setting the “Ambient Occlusion” material property in the default Cesium materials.
Fixed a crash when attempting to use Cesium Actors with World Partitioning.

Check the Cesium for Unreal (UE5) release and the Cesium for Unreal Samples release for the full list of updates.

Cesium for Unity 1.3.0 Release

Cesium for Unity v1.3.0 is now available. It contains some important bug fixes and usability improvements, including:

Cesium components now appear in a “Cesium” category in the Component menu, and have a custom icon.
Fixed a bug that could cause missing textures when using two raster overlays with the same projection on a single tileset.
Fixed a bug where Cesium3DTileset would not reflect changes made to the properties of its opaque material in the Editor.
Fixed a bug where changing the origin on a CesiumGeoreference would not propagate these changes to the active CesiumSubScene, if one exists.
Reduced the amount of extraneous camera rotation in the CesiumCameraController after a frame hitch by using Time.smoothDeltaTime.
Fixed a bug that caused mipmaps to be generated for textures that shouldn't be mipmapped, sometimes leading to cracks between tiles and other problems.

Cesium for Omniverse 0.7.0 Release

Highlights of this release include:

Set better default values when loading glTFs with the KHR_materials_unlit extension. This improves the visual quality of Google 3D Tiles.
Improved installation process by forcing application reload when Cesium for Omniverse is first enabled.
Changed material loading color from red to black.
Added /CesiumSession prim for storing ephemeral state in the Session Layer, including ecefToUsdTransform.
Fixed credits not appearing on all viewports.
Updated to Cesium Native 0.24.0, which adds support for 3D Tiles 1.1 implicit tiling.
