I don't think, that such detailed things are possible with the actual map format
You don't have to make them look exactly alike,
If only DP had these sorts of maps :p
Other map format.
+New engine = new game. - stupid idea, unrealistic.
Hush payl, this is already on the feature vote and has been discussed as a possibility for some time.Just shift it to quake2world's map format/renderer, maybe with model collision added as well, less changes needed, same editors can be used, more efficiency and potential for nicer graphics...
