I have some gray scale height maps that I wanted to import into the terrain.
So far I have had no luck I did download the hmcs conversion tool http://www.lilchips.com/dgunreal/tools-hmcs.asp and changed my height map to a bmp with the unreal g16 heightmap .
When I check the height map only box and then click import height map I get a large box in map not in terrain.
So I tried again checking the box into currant and also height map when I click import the editor crashes on me.
I tried it that way three times and crashed every time.
The editor for the most part doesn't crash for me and btw the video tutorials that came with the limited addition of this game are great but also so lacking on more of the medium to advanced editing that I was hoping for.
