Hi @abbe11​ 

I'd recommend using the PointCloundExpressionEvaluator to create a new component, the expression should be something like @index()/1000. Then, use a PointCloudSplitter to split by that component.

I've attached some images and a workspace as an example.  

Have you looked at the PointCloudDensityTiler on FME Hub?

Thanks @jdh​ , that almost does what I am after. However, Is it also possible to get a "tile-id" to achieve the final split/fanout on?

Thanks @siennaatsafe​, this works well. The newly created component "t" isn't exposed as an component, right? (It is still possible to use it in pointcloudsplitter though, but not as a component in "split by"- drop down.)

You could just add a Counter to get an id for the fanout.

Hi @abbe11​ ,

That's right, it won't count as an exposed component, but can be written in the pointcloudsplitter (however not selected by the dropdown).
