Hi @vincentstreigna, this was just added to FME so my guess is that you are better off by contacting Safe for some assistance and I doubt there are any articles on the matter yet.
Im not sure if the 3D-Tiles writer will work with geometry (gltf). I have not tried it yet with meshes. It does work with point clouds. But there are some details that need to be worked out...needing some tips on how to get the tileset.json writer to set up a quad tree structure for example.
Currently Using build 17228 WIN64
The docs are a bit light. and I know this is a bit of a pre release...

setting cesium_priority does not seem to affect the order of the tiles in the hierarchy and not all .pnts tiles get referenced. FYI: I use the PointCloudDensityTiler to create a couple of levels of tiles which all get written to .pnts tiles but not all tiles get referenced. Thanks for any tips from the developers...
Morning @vincentstreigna, I did a quick test and find the latest Cesium tileset writer. given 3d surface geometry will write out batched 3d model files (.b3dm) files. More to come for sure as we keep putting the tileset writer through the motions.
