Cesium for Unreal v1.3.1

1.3.1 - 2021-06-02

• Temporarily removed support for the Android platform because it is causing problems in Epic's build environment, and is not quite production ready in any case.

Cesium for Unreal v1.3.0

1.3.0 - 2021-06-01

Breaking 📣

• Tileset properties that require a tileset reload (URL, Source, IonAssetID, IonAccessToken, Materials) have been moved to private. Setter and getter methods are now provided for modifying them in Blueprints and C++.
• Deprecated CesiumGlobeAnchorParent and FloatingPawn. The CesiumGlobeAnchorParent functionality can be recreated using an empty actor with a CesiumGeoreferenceComponent. The FloatingPawn is now replaced by the DynamicPawn. In a future release, the DynamicPawn will be renamed to CesiumFloatingPawn.

Additions 🎉

• Added support for the Android platform.
• Added support for displaying a water effect for the parts of quantized-mesh terrain tiles that are known to be water.
• Improved property change checks in Cesium3DTileset::LoadTileset.
• Made origin rebasing boolean properties in CesiumGeoreference and CesiumGeoreferenceComponent blueprint editable.
• Made 3D Tiles properties editable in C++ and blueprints via getter/setter functions. The tileset now reloads at runtime when these properties are changed.
• Improvements to dynamic camera, created altitude curves for FlyTo behavior.
• Constrained the values for UPROPERTY user inputs to be in valid ranges.
• Added M_CesiumOverlayWater and M_CesiumOverlayComplexWater materials for use with water tiles.
• Exposed all tileset materials to allow for changes in editor.
• Added TeleportWhenUpdatingTransform boolean property to CesiumGeoreferenceComponent.
• Added a "Year" property to CesiumSunSky.
• Added the ability to use an external Directional Light with CesiumSunSky, rather than the embedded DirectionalLight component.

Fixes 🔧

• Fixed a bug that caused rendering and navigation problems when zooming too far away from the globe when origin rebasing is enabled.
• Fixed a bug that caused glTF node translation, rotation, and scale properties to be ignored even if the node had no matrix.
• Cleaned up, standardized, and commented material and material functions.
• Moved all materials and material functions to the Materials subfolder.
• Set CesiumSunSky's directional light intensity to a more physically accurate value.
• Moved Latitude before Longitude on the CesiumGeoreference and CesiumGeoreferenceComponent Details panels.

In addition to the above, this release updates cesium-native from v0.3.1 to v0.4.0. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v1.2.1

1.2.1 - 2021-05-13

Fixes 🔧

• Fixed a regression in Cesium for Unreal v1.2.0 where GlobeAwareDefaultPawn lost its georeference during playmode.
• Fixed a regression in Cesium for Unreal v1.2.0 where the matrices in CesiumGeoreference were being initialized to zero instead of identity.
• Fixed a regression in Cesium for Unreal v1.2.0 that broke the ability to paint foliage on terrain and other tilesets.

In addition to the above, this release updates cesium-native from v0.3.0 to v0.3.1. See the changelog for a complete list of changes in cesium-native.

Cesium for Unreal v1.2.0

1.2.0 - 2021-05-03

Additions 🎉

• Added dynamic camera that adapts to height above terrain.
• Added Linux support.
• Added support for Tile Map Service (TMS) raster overlays.

Fixes 🔧

• FEditorDelegates::OnFocusViewportOnActors is no longer unnecessarily subscribed to multiple times.
• Loading tileset ... is now only written to the output log when the tileset actually needs to be reloaded.
• Fixed a bug where collision does not update correctly when changing properties of a tileset in the editor.
• Fixed a bug that caused tiles to disappear when "Suspend Update" was enabled.

Cesium for Unreal v1.1.1

1.1.1 - 2021-04-23

Fixes 🔧

• Fixed a bug that caused tilesets added with the "Add Blank" button to cause an error during Play-In-Editor.
• Fixed a bug that caused ACesiumGeoreference::TransformEcefToUe to be much less precise than expected.
• Moved the BodyInstance property on Cesium3DTileset to the Collision category so that it can be modified in the Editor.

Cesium for Unreal v1.1.0

1.1.0 - 2021-04-20

Additions 🎉

• Added macOS support.
• Added support for the legacy gltfUpAxis property in a tileset asset dictionary. Although this property is not part of the specification, there are many existing assets that use this property and had been shown with a wrong rotation otherwise.
• Changed the log level for the tile selection output from Display to Verbose. With default settings, the output will no longer be displayed in the console, but only written to the log file.
• Added more diagnostic details to error messages for invalid glTF inputs.
• Added diagnostic details to error messages for failed OAuth2 authorization with CesiumIonClient::Connection.
• Added a BodyInstance property to Cesium3DTileset so that collision profiles can be configured.
• Added an experimental "Exclusion Zones" property to Cesium3DTileset. While likely to change in the future, it already provides a way to exclude parts of a 3D Tiles tileset to make room for another.

Fixes 🔧

• Gave glTFs created from quantized-mesh terrain tiles a more sensible material with a metallicFactor of 0.0 and a roughnessFactor of 1.0. Previously the default glTF material was used, which has a metallicFactor of 1.0, leading to an undesirable appearance.
• Reported zero-length images as non-errors, because BingMapsRasterOverlay purposely requests that the Bing servers return a zero-length image for non-existent tiles.
• 3D Tiles geometric error is now scaled by the tile's transform.
• Fixed a bug that that caused a 3D Tiles tile to fail to refine when any of its children had an unsupported type of content.
• The Material property of ACesium3DTiles is now a UMaterialInterface instead of a UMaterial, allowing more flexibility in the types of materials that can be used.
• Fixed a possible crash when a Cesium3DTileset does not have a CesiumGeoreference or it is not valid.

In addition to the above, this release updates cesium-native from v0.1.0 to v0.2.0. See the changelog for a complete list of changes in cesium-native.
