Dinos - Unused regions being used.
Source: https://ark.gamepedia.com/ Allo: Regions 1/2 Anglerfish: Region 4 Archaeopteryx: Regions 1/3 Castoroides: Regions 2/3 Diplodocus: Regions 2/3 Dire bear: Regions 1/2/3/4 Electrophorus: Regions 2/3/4 Gacha: Regions 1/4 Galli: Region 3 GasBags: Regions 1/3 Manta: Regions 2/3/5
Did not have time to check other dinos, I would recommend going through them.
The Anglerfish actually uses the fourth region. I'll update the wiki once I go through the whole list. Hopefully you don't mind, Cad.
Castoroides has some accidental cyan (blending artifact) on its colorization mask which translates into region 3 on that poor thing. It's barely visible in the typical color space so I guess it's fairly safe to skip. Green bits on screenshot.
Regions for all mentioned creatures other than Manta and Electrophorus should be now updated in the data. I'll update the remaining two (and some other species) once the workflow is a bit more streamlined (don't want to lose track of renders needed to be done for the wiki).
Reviewed Manta and Electrophorus. No difference between Manta in ASB and on wiki, but Electrophorus did have two regions not listed on wiki. I'll submit Eel's fourth region to be disabled as an extractor patch though.
