übrigens verwende ich nur die _0 keine weiteren lodstufen

For instance for "house_0.wmb" the engine expects "house_1.wmb", "house_2.wmb", "house_3.wmb" as LOD files. by slin/manual


so there have to be the other files. if you just want to clip them away with the help of the LOD, try to make an empty wmp, compile it, and use the <empty> compiled files (after a renaming) as your LOD steps. i bet it counts that the _1 _2 and _3 files are there.
