• Breaking changes for globe anchors:
  • Removed anchor_xform_at_path. Globe anchors can now be created directly in USD.
  • Split cesium:anchor:geographicCoordinates into separate properties: cesium:anchor:latitude, cesium:anchor:longitude, cesium:anchor:height.
  • Globe anchors no longer add a transform:cesium op to the attached prim. Instead the translate, rotateXYZ, and scale ops are modified directly.
  • Removed cesium:anchor:rotation and cesium:anchor:scale. Instead, use UsdGeom.XformCommonAPI to modify the globe anchor's local rotation and scale.
  • Globe anchors now use the scene's default georeference if cesium:georeferenceBinding is empty.
  • For migrating existing USD files, see CesiumGS/cesium-omniverse-samples#13
• Breaking changes for imagery layers:
  • CesiumImagery was renamed to CesiumRasterOverlay and is now an abstract class. To create ion raster overlays, use CesiumIonRasterOverlay.
  • MDL changes: cesium_imagery_layer_float4 was renamed to cesium_raster_overlay_float4 and imagery_layer_index was renamed to raster_overlay_index.
  • ion raster overlays now use the scene's default ion server if cesium:ionServerBinding is empty.
• Breaking change for tilesets:
  • Tilesets must now reference raster overlays with cesium:rasterOverlayBinding.
  • Tilesets now use the scene's default georeference if cesium:georeferenceBinding is empty.
  • Tilesets now uses the scene's default ion server if cesium:ionServerBinding is empty.
• Added support for polygon-based clipping with CesiumPolygonRasterOverlay.
• Added ability for multiple tilesets referencing the same raster overlay.
• Added ability to reorder raster overlays in UI.
• Added context menu options for adding raster overlays to tilesets.
• Fixed multiple globe anchor related issues.
• Fixed excessive property warnings when using custom materials.
• Fixed adding raster overlays to selected tileset in the Add Assets UI.
• Fixed loading 3D Tiles 1.1 implicit tilesets.
