Hi @Fabio_Rob,
As you’ve indicated, Twinmotion does not directly load 3D Tiles.
One workflow I’ve used in the past to extract 3D Tiles into Twinmotion is to use clipping in Cesium ion, which turns areas of the 3D Tiles data into glTF that can subsequently be imported into Twinmotion.
There are a few caveats - glTF will lose any georeferencing information, however as Twinmotion doesn’t contain any georeferencing functionality this isn’t really an issue. It just means you’ll need to manually align your content to any other geospatial data.
Another is some 3D Tiles cannot be clipped due to licensing terms (eg. Google Photorealistic 3D Tiles). However, if you’re creating your own 3D Tiles in Cesium ion this shouldn’t be an issue for you.
