I did check out a few topics related to this but couldn't quite find the answer so I'll just ask the question here directly; How do you make terrain in Nexuiz maps using gtkRadiant as the map editor? I'm guessing the latest original Radiant doesn't come with any features for terrain building and terraforming, and the only type of terrain the engine supports is BSP based terrain like every other surface. I was first hoping Radiant might have some built-in support for making terraformable terrain with raise, lower, smooth and flatten tools like you can do in other systems and engines which have terrain like that.
So what's the easiest way to make terrain in a map the way you want? I'd prefer something that doesn't require you to make the terrain externally then export - import it as I may want to modify the terrain over what I already have on the map and blend it carefully over other surfaces. Maybe there's at least a plugin for gtkRadiant to allow you to make a brush that can be terraformed "lively" from the 3D viewport? That would rock if possible... I also don't expect it to support multi-texturing as that's likely an engine limit, that's something I would do in the texture itself, just want a way to terraform terrain geometrically if that's possible. Thanks.
