How to populate random points in an area with 3d objects?

Hi,

I'm a complete noob with FME with just a few days of dabbling around with it.

So far I've managed to filter out areas from a shape file and extrude those areas with a value from a variable and send it to Cesium Ion and display it in Unreal Engine.

But now I'd like to know how I can add random points to those areas and populate those points with a 3d-object and use the generated tileset with Cesium Ion and Unreal.

So far this https://community.safe.com/s/question/0D54Q000080hDPMSA2/adding-a-3d-model-and-georeferencing-it-with-multiple-xy-points, is the only thing I've found related to this. But haven't been able to get it to work.

See attachments for my current pipeline, which does bring a single object to Cesium Ion, but no location data (Tileset location has not been set).

How far off am I?

Thanks in advance.
