Is there anyway to convert the maps so they can be opened in 3D Max? seems like the easiest way but cant find anything about it.
I also was thinking about useing the mapoverview in IGOR but cant find anything to zoom out with, it seems locked. but patching a lot of them together could work combined with the generated command map (see below). atleast would work faster than patching something together from loose RGB files
Generating a command map in IGOR(IT version) makes a grey map overview with a lot of detail could be usefull for adding some extra detail. no color or texture tough.
