The Generate LOD Chain scenario automatically creates Level of Details (LODs) out of each mesh present in the scene (more information about LODs here)

LOD0 level is the original mesh. LOD1 and LOD2 levels are created by duplicating and decimating the initial mesh (see Decimate function, and About Decimation), each time with stronger, more destructive values.

Parts are renamed with a suffix (_LODn) to fit the naming convention handled by most game engines to automatically add LODs behaviors.


This scenario works for meshes only (requires the selected parts to be tessellated first).

To go further

Refer to the Output window to check all the algorithms applied step-by-step during scenario execution.

If you want to adjust decimation values, add a new LOD, or replace LOD2 by a ProxyMesh instead of decimating the original meshes, it is possible by (duplicating and) editing the Python script PiXYZ-STUDIO_Scenario-GenerateLODChain.py.
