i got a terrain with a decent polycount. now i try to reduce the polycount via the polyreduce node. to avoid that the hole terrain is affected i split it into several chunks. now i want to bind the reduceamount to a camera. works fine but dunno how to use it per chunk.

any suggestion ?

you can directly use Distance mode in Polyreduce

here is an example of using Polyreduce within Foreach to reduce each slice based on distance to camera
