Export tiled model to Cesium ion

Hey,
I have not managed to succesfully exported the tiled model to Cesium ion. The model ends up about 20 meters over our local data.
We suspect that the export to wgs84(EPSG 4326) dont handle the hight that well, maybe EPSG 4978 would be better but all options appears to be greyed out when export to 3D tiles.
Any ideas what to do to succesfully export 3D models to watch in Cesium?

Hi Filsun,
I confirm, same issue with me.
In AGISOFT I am searching how we can apply a shift in Z before uploading to CESIUM
maybe the easiest way is to find in Agisoft Reference Setting WINDOW if there is an dedicated EPSG code that would correspond to your planimetric local Ref Frame + ellipsoidal height.
Cesium only accepts ellipsoidal height...
Does Agisoft understand combination of EPSG code ? such as <planimetric EPSG code> + <altimetric EPSG code>

"In AGISOFT I am searching how we can apply a shift in Z before uploading to CESIUM"
Or export the tiled model to tls with the right heights, not only ellepsoid heights.

Hello Antoine,
Which altitude reference you are using in Cesium ION: ellipsoid height or world terrain? Please also confirm that the model is properly georeferneced in Metashape, for example, check points show acceptable errors.
