From my point-of-view it’s a really valuable update, that’s important to get that feedback from the official Cesium team, thanks for that and the clarification! Fingers crossed the Blender integration will happen at some point - your joint move with Google for photorealistic 3dtiles might make things move faster since Blender is the essential 3d engine for lots of studios among the most recognized.
I’ve seen the grant for Qgis integration, which is also a great news - there is some interrogation as to why North-Road did receive the grant while Oslandia had already undertaken large part of the work towards complete integration, but it’s a great step in the right direction - see Streaming large 3D dataset, support for 3Dtiles · Issue #225 · qgis/QGIS-Enhancement-Proposals · GitHub.
Support for OGC 3Dtiles by major software vendors, oss or proprietary, for broader use of the standard specification is the way to go for streamlined adoption. Thanks again to the whole team for all your efforts!
