I've done creating a tile based level from .png image (my editor became useless, since you can simply draw stuff in Gimp or such). After creation I merge all tiles into one model (on the picture you can see 3 entities created, one for collision models, one for visual darker faces and the last one for bright faces (fake shadow/light from sun)). So far I do have problems with setting different skins, for merged models (I could only set U, V - in MED, so I need to have separate model for each texture.. that's kind a odd and I don't want to create everything dynamically). Thanks to MasterQ32 and TUST in general (to all contributors as well!). Next thing to add is pathfinding.
