Current questions and answers regarding the map editor.

Well, darn it. I can’t do what I can’t do – I tried to mess around with some 3D programs, but it was unsuccessful. Okay, I’ll see what I can do with the map and textures; maybe I’ll abandon the idea of the river altogether. Thanks.

P.S. As it turns out, I made a mistake – a regular M_GENERIC on such a narrow river works no worse than M_CLOUDS_H5. Now the river flows downwards, so the issue is resolved.
