Actually they're using derived classes for meshes, that's why umodel couldn't recognize almost all of them.
Here is specific build with proper support for meshes (
link, updated). Some materials are custom or not linked properly. Also, you need to choose lzx compression manually at startup screen, otherwise you'll get crash like the mentioned above.
Update: Specific build is adjusted to support static meshes from Lollipop Chainsaw properly.
Update 2: Specific build is updated to support static meshes from Black Knight Sword properly.
Update 3: Specific build is updated to support Let It Die (instead of separate build).
