have a nice day everyone, i have a very big, scanned point cloud, and my client wants to have it as a obj mesh the final result that served me is 3dtiles from cesium / when i am trying to google how to get obj from 3dtiles, it forwards me to FME

You unfortunately can't read Cesium 3DTiles with FME. Your best bet is to follow the steps nosradom outlined in the workaround here: https://community.safe.com/s/bridea/a0r4Q00000HbsHvQAJ/create-texture-files-from-point-cloud-andor-mesh-vertices (involves converting the point cloud to an OBJ in FME and then use MeshLab to apply the vertex colours into a texture for the OBJ. I hope this helps.

Thank you for your help. I followed the nosradom steps you shared. It helps me a lot. I did the point cloud to OBJ conversion in FME and then used MeshLab to apply the vertex colors to a texture for the OBJ. I have successfully converted it as obj mesh. doodle baseball
