There are some modders resources like "Strotis Castle Wall", "Strotis Manor Resource" which have nice objects, but doesnt have meshes for LOD building. Pretty common problem for modders resources.

Maybe someone have some kind of tutorial how to make it. Without using photoshop if possible . I see that its just very simple meshes, sometimes like a cube, but how exactly make it with proper texture.

Or maybe someone able and want to make this meshes
