Importing Skeletal Mesh LODs
Skeletal Mesh LODs can be imported through the Mesh Details
panel in Persona
under LOD Settings
Persona is the animation editing toolset within UE4. Refer to the Animation Editors for additional information.
- To apply an LOD to a skeletal mesh, double-click the animation asset from the Content Browser to open Persona (example sequence pictured below).
- In the Mesh Details panel, scroll down to find the LOD Settings section and click the LOD Import option.
In the file browser, locate and select the FBX file you want to import.
- The imported LOD is now added to the Mesh Details panel.
- Under each LOD, the Display Factor setting indicates when to use the LOD. In the example pictured below, LOD0 is used when your position is closer to the Skeletal Mesh, whereas LOD1 is used when your position is further away from the Skeletal Mesh.
Using a small Display Factor tells Unreal Engine to use the LOD when your position is further away from the Skeletal Mesh. Larger Display Factors tell Unreal Engine to use the LOD when your position is closer to the Skeletal Mesh.
