Q: I can't save map source files from the editor, what the hell is going on?A: The editor & builder suite does not like space characters in the complete path containing the map filename, including map name. This is a legacy problem, a limitation that came to exist due to use of the tools in heterogenous environment over the network, but the important thing for you is to realize that you need to install the engine and of course the editor to a different path than the standard one. For instance "C:\DNMP" is a good one. But the space in "Program Files", or the many spaces in "Duke Nukem - Manhattan Project" are not acceptable for the editor, as well as would be naming a map "My First Map.vex". Stay away from spaces in filenames and paths, and you will be fine. The engine is not limited this way, so the game itself and any user maps can be installed into any folder, but the developments tools have their quirks.Q: The tutorial was too simple to figure out how to make a more complex map. Could you give us a more detailed overview?A: Nope. Open one of the many tutorial maps that you will find in the dnmp\duke\map_src folder. There are many examples of how to use and connect entities to create complex behavior in your maps, you should be able to figure it all out. In fact, this tutorial author's knowledge about the intricacies of DNMP entities and proper DNMP map construction are very limited, and probably on the level of most newbies. While the editor was created at SCS Software, the game code, game entities and their logic was all written at Sunstorm, who have heavily customized the engineQ: When I put my second brush into the map, I can't see it in the textured preview mode. Why?A: You need to select the topmost, "level" node in the group hierarchy of the map, and change the "CSG starting with" property to "void space". The default property is suitable for indoor maps with lots of corridors and using "sub" brushes to cut those corridords, but this is not the case in many DNMP maps.Q: Any further tips?A: When you open the file named DNMP Prism Help.chm that's a part of the editor download package, you will find quite a lot of usefull info there about the editor. The document is worth reading in its entirety, but specifically for the editor usage the sections Technical Info - Key Command Listing and Tips and Tricks are very good. You should also pay attention to the Tip of the Day popups in the editor.
