i know that an AI, a mdafide canbilld, and terain can be added to the map kmp.
the AI is named defult and is in a TXT format.
the terain tileset nuber can be found at the terain.hpi.
there was a good turoreal at the RX site for the canbilld.
when opaning the map with the hpi viewer the kmap and terrain and all othere things added should be seperate folders.
if you want to chaing somthing just look at the data.hpi for it and try it out.
There are loads of modern ideas but new ideas are rare.
