Hello, The municipality of Rotterdam is trying out using Unity with our Cesium tilesets (www.3drotterdam.nl). Unfortunately the instanced tilesets do not seem to work. Are they supported in Unity? We’ve tried it with: Trees https://www.3drotterdam.nl/datasource-data/b9294d5b-79e0-4744-ac88-b61e3e…

Hi @Jorri , welcome to the community! As @Tom_Lee said, unfortunately, no, Cesium for Unity does not support instancing yet. Instancing is available in Cesium for Unreal, though, in case that helps at all.
