Hi, when I use 3D Tiles and b3dm with coordinates in ECEF without a batchtable, I can see my models. But when I write the batchtable, I can’t see my models anymore. Is it because I don’t have a “properties” in my tileset.json ? ---

Hi, Possibly. Did you try adding the properties section? Did you look at the example sample data (gzipped): [https://github.com/AnalyticalGraphicsInc/cesium/tree/3d-tiles/Specs/Data/Cesium3DTiles](https://github.com/AnalyticalGraphicsInc/cesium/tree/3d-tiles/Specs/Data/Cesium3DTiles) Patrick ---

Sorry for the late response, but maybe this helps if someone has the same problem. I had to add two extra bytes into the buffer after a batchID, so the byte stride is 4. Somehow just the two byte of the unsigned short don’t work.
