Mods and the map editor

[Captain Kwok]

The path.txt has to be set to the mod directory in order for the map editor to use the mod images and files.

[Fyron]

If you use the mod launcher, select the mod from the list, and hit Edit Maps.

The Imagemod is not a mod by itself, just a collection of pictures that can be used by other mods.
You have to use a mod that adds new sector types and other required data changes, such as FQM Deluxe.
