WFMap -- Map Editor (ensure you have set your mul settings under option->mulsettings). WFMulti - Multi/Structure/Art editor. Build any structure based on art tiles, at any altitude offset. UOARExtractor - Have a UOAR database, and no mlt files? Put this in your UOAR client direcotry, then edit the names in the left pane as desired, and drag them over to the right pane directory, and you will get MLT files from them. Multicache = Same as UOARExtractor, but for multicache.data. Ensure the multicache.xml file is set properly. MLTPlacer - Made a terrain.bmp for UOL transistions. But now you want to add those buildings , dungeons, caves that you made in the Multi Editor. Just use this and drag any MLT file to the image. Move it around, right click and delete it, etc. Save the "structure" file to be processed by Map Generator. Ensure the mltplacer.xml file is set correctly. MapGenenerator uses UOL Transistions and data to build a new map for you. One can set the mapgenerator.xml, and make selections of some settings via the user interface. It will generate your map in about 10 mintues for a Felucca or Trammel size, even on low memory system. If you have a structure file, it will also include those buildings, structures, etc. diffs.rar isn't really part of the WorldMaker suite persay. It allows one to see what block (art or map) is patched by the dif file. One can choose to delete the dif patch, or put it into the mul file (keep restores it to is orginal state of begin patched). No writing occures until save is performed. Qt.rar and msdlls.rar are the dlls needed for the programs. Put them in windows/system32 directory.
