DRAKHYSYS INFINITY TILESET WORKBENCH V4.8
MULTI-AREA TRANSITIONS / ENTRANCES

V4.8 upgrades the AREA TRANSITIONS / ENTRANCES tab into a multi-area network editor.

CORE RULE
- The source area identity always comes from the imported ARE filename.
- DR0001.ARE remains DR0001.
- DR0002.ARE remains DR0002.
- Export All writes each loaded area back under its original resref/name.

MULTIPLE EXITS
- Load any number of ARE files with ADD ARE(S).
- Switch source areas with the Loaded source areas selector.
- Each source area may contain any number of named Travel Regions / exits.
- Each exit independently selects:
    destination area
    destination entrance
    party-required state
    exit polygon

MULTIPLE ARRIVAL ENTRANCES
A destination area may contain any number of entrances.
This is useful when several maps or several exits lead to the same destination.

Example:
DR0001 / TO_DR0003_A -> DR0003 / FROM_DR0001
DR0002 / TO_DR0003_B -> DR0003 / FROM_DR0002

When DR0003 is selected, the Incoming exits targeting this area list displays both source routes.
Select one incoming exit, press CREATE ARRIVAL FOR THIS INCOMING EXIT, place the entrance, and save it.
Repeat for the second incoming exit. Each source exit is then linked to its own named arrival entrance.

DESTINATIONS
- Loaded ARE files appear automatically as destination choices.
- Optional chitin.key scanning adds all registered ARE resrefs to the destination list.
- Destination area remains editable for custom AREs not currently loaded.
- If a destination ARE is loaded, its known entrances appear in the destination-entrance selector.

EXPORT
- EXPORT CURRENT AREA writes only the selected source ARE.
- EXPORT ALL LOADED AREAS writes every loaded source under its original area name.
- VALIDATE LOADED TRANSITION NETWORK checks that loaded destination areas contain every entrance referenced by loaded source exits.
- External/unloaded destinations are allowed but reported as warnings because their entrance tables cannot be checked locally.

The editor still preserves unrelated ARE structures by appending replacement navigation tables rather than rebuilding the complete area.
