# Pet::AutoModeling provides utilities for automatically modeling items on pet
|
||
|
|
# bodies using the NC Mall preview API. This allows us to fetch appearance data
|
||
|
|
# for items without needing a real pet of that type.
|
||
|
|
#
|
||
|
|
# The workflow:
|
||
|
|
# 1. Generate a combined "SCI" (Species/Color Image hash) using NC Mall's
|
||
|
|
# getPetData endpoint, which combines a pet type with items.
|
||
|
|
# 2. Fetch the viewer data for that combined SCI using the CustomPets API.
|
||
|
|
# 3. Process the viewer data to create SwfAsset records.
