Skeletal Mesh Reduction Tool Overview
In the past, if you wanted to reduce the rendering cost of your Unreal Engine 4 (UE4) projects Skeletal Meshes you had to create the needed Level Of Detail (LOD) Meshes in your Digital Content Creation (DCC) program of choice and then manually import each one. Or you could use an integrated 3rd party tool like Simplygon to do this for all from within the UE4 Editor. Since both of these methods of creating LOD's are not ideal as they can be very time consuming the Skeletal Mesh Reduction tool was created. The Skeletal Mesh Reduction tool allows you to create LOD for your Skeletal Meshes inside the UE4 Editor.
