mine grass, missing texture?

[Torquemada]

Any idea why mine_grass has black texture? Am I missing something here? See this image:

mine_grass uses a heightmapMaterial instead of a floor model, so you need to place a HeightmapComponent somewhere on the map. This is what the forest_heightmap object is for.

Just came from the can and it hit me, of course It probably works like the outdoor areas - heightmap!
Thanks for the reply, but I figured it out, at the can of all places.
