toneddu2000 First is about
misc_model entity type. For example if I have some object in Blender and I want it to be exported as
misc_model I add logic property "classname" = "misc_model". After that an ASE file will be created and bind to a result MAP file MAP during export.
Misc model could be a link to other misc_model. It might be useful when one has a lot of identical objects. In this case only one object is exported as an ASE and others should have property "ref_to" = "<name of mesh in Blender>". Of course, it is optional, but I'm sure it minimizes exporting time and HDD space consumption
motorsep info_* is exported in the following way. If you set logic property of any mesh to "classname" = "info_*" (info_* means an exactly that entity type what you need), it will be exported as an appropriate entity.
"origin", "angle" and "scale" properties are calculated automatically from object matrix.
I've finished exporting "item_*" entities group from Blender also. It will be available here soon. Now I'm testing it by making some map using all exporter abilities. Unfortunately, I'm awful artist and even meet difficulties copying a construction from picture to Blender

I have an amazing place near my house and I dreamed about making a map with it. ( It has Google Earth coordinates: 55 deg 58 min, 02 sec C; 37 deg, 10 min 16 sec B. People in my city use this place to play Paint Ball - it's like Nexuiz

It's one of Communism ghosts - planned as particles accelerator and electronics center, nut now it's perfect ruin looking like after war
