Modding Cairn

Has anyone been able to decompile the “world001.map” file for editing existing Grim Dawn regions? So far I’ve been able to load the entire file into the editor as a (.wrl) into a new mod.
Without the associated decompiled files:
(.lvl .rlv .sd), the editor doesn’t allow terrain/painting modifications etc.

Perhaps I’m missing something related to the “ArchiveTool” functionality?
