In the config file it looks like this:
+TextureLODGroups=(Group=TEXTUREGROUP_World,LODBias=1,LODBias_Smaller=-1,LODBias_Smallest=-1,NumStreamedMips=-1,MipGenSettings=TMGS_SimpleAverage,MinLODSize=64,MaxLODSize=2048,MaxLODSize_Smaller=-1,MaxLODSize_Smallest=-1,OptionalLODBias=0,OptionalMaxLODSize=2048,MinMagFilter=“aniso”,MipFilter=“point”)
