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.

Hi. AFAIK there is an issue of this. Support for i3dm and Instanced 3D Models opened 10:29AM - 18 Feb 24 UTC (UTC) [image] YerichoDev enhancement …

Hi Tom_Lee, thanks for the reply. I’ve seen these posts (also on this forum) but since a year has passed I was hoping for some development. Also because Unreal has had the support for a while now. I also noticed a mention of i3dm in the latest patch log of Cesium for Unity. But can I conclude there’…

Hi I am also looking forward to the feature. It can be implented referencing other type of 3D tiles data processing in Cesium Unity. There is already i3dm processing code in Cesium Native. :slight_smile: Regards.

Understood, cheers! Regards, Joris

I just saw your later message that instancing isn’t working in Unreal. If you can give us more details about that, we can take a look. It should be working there, as far as we know.

Thanks for your reply Kevin, it’s good to know for sure that instanced tilesets don’t work yet in Unity.
