are using unity or ue4? because if ue4, then you don’t have to worry about lods that much since they now have automatic lod system implemented for skeletal meshes. and it works pretty damn good. the sniper rifle that i’m working on currently is using skeletal meshes due the animations and easier usage with other skeleton. and i used ue4:s automatic lod system on it and it work brilliantly. and while i say automatic, you ofcourse need to make the parameters for the decimation settings when they kick in and how it will decimate. but you don’t have to manually do that in blender and export/import multiple files. just create the mesh that is closeup. and then let the tool worry rest.
if its unity, then i don’t know. maybe @jgonzalez can answer that one?
