Ah, I can't help you. The whole reason I got into RPG mapping was there seemed to be two kinds of maps found in most RPGs - old school (yech) and photorealistic like in video games, and neither extremes suit my taste. My level of hand-drawn and decked out color with implied 3D bevels and shading, is about the level I like, that's why I make 'em.

Your project does look interesting - if you're ever interested in the step between the two kinds of maps I describe, then contact me, I might be interested.
