I'd like to build a terrain like the Giant's Causeway.
Problem is that I cannot find a way to build a hightfield that has areas with sharp edge hexagonal patterns. I don't think that making those columns with texture will produce wanted effect. Columns can be larger than real ones, if it makes things any easier. Any ideas or is this impossible with L3DT? I was thinking that one solution could be that I'll made a hightfiend with columns in photoshop and merge it with the generated hightfield.
