Issue visualizing metashape export pointcloud data in cesium ion

[ppant]

I processed the data in metasape and save the point cloud in the correct UTM zone. Then use entwine to generate the 3D tiles. When loaded in the viewer point cloud are floating in the air. Not sure how to add the high offset inside metashape.  When I read more it looks like what metashape is doing, z is just the altitude geotag not further correction applied when I export data to correct UTM zone. Is there a way to correct those and bring data to the ground? Via a script

Thanks
