RTF is a global modification that replaces all towns in the game.

I import some objects from GEMRed separately into the map, without replacing the old objects. But I don't know how to import objects from Anno and other games! So, I would be grateful if you could tell me... hmm... where to find them.

Okay, I'll figure it out now.

In general, exporting from Anno turned out to be very simple: the game archive is opened with a program from Playground, textures are in DDS format, models are in GR2 format and can be viewed as a five-pointed skeleton, but there were problems with converting them to OBJ due to poor guides, but if you figure it out, everything will be simple.

I've started a free game now, and I'm taking screenshots of cool models that can be ported.
