Hierarchical LOD Outliner ​

For worlds created using World Composition, not World Partition, Hierarchical LODs (HLODs) are managed using the HLOD Outliner. You can find the HLOD Outliner under Window → Hierarchical LOD Outliner. HLODs can either be a merged version of the objects, a merged and simplified version or an approximate version. Simplygon can be used for the simplify workflow.

The Simplygon plugin provides an under-the-hood integration for users that want to create good-looking simple proxy LODs with one single baked material. It uses the Simplygon Remeshing pipeline for processing and will run distributed if you have set it up to do so.

HLOD Outliner example ​

Make sure you have set the Proxy LOD Module / Hierarchical LOD Mesh Plugin to Simplygon, see Getting started to learn how.

Then, you simply need to make sure that in your World Settings, under the HLOD System section, that you have a Hierarchical LOD Setup that have it's Simplification Method set to Simplify and that's it.

For more information on how you use the HLOD Outliner to build your HLODs we recommend reading the Unreal Engine documentation.
