@Anarch16sync was right- the mod internal files can still be optimized a lot to reduce overall mod size and the main target is the MEDIA/MODELS/PCS folder at 50MB.

Next is the WARDROBE folder at 32MB, but to implement the Alch gauntlet there's not really much you can do about that.

The Vanq has a very efficient set-up, placing its class-specific files (about 1MB each) into /PCS/HUM_M and HUM_F folders shared with the game.

In contrast the Alch and Destro folders are dedicated folders, containing both the class-specific files AND complete reproductions of the game's hum_m and hum-f files (.mesh, .skeleton and .animation files). That's 4 folders at about 10MB each.

I will update to mirror the Vanq's set-up for the other classes and I plan to have this done by the weekend.
