Custom Grass

[Ukko]

Hey, is there anyone, who can tell how to make a custom grass? I took an overview on the grass nifs placed in the data\meshes\plants directory. I can import them to blender, or Nifscope, but don't know how to properly export them. The model is very simple - its just a couple of rectangles placed at different angles, so it should be easy to export it from blender and assign to some land texture. The problem is that grass models exported from blender, or retextured in NifScope don't appear in game.
