THIS MOD IS NO LONGER REQUIRED. Some extraneous changes to the game and weapon_costumes.xtbl have broken customisation on the Penetrator and Rectifier. This weapon_costumes.xtbl fixes this and restores customisation for me and IdolNinja. Changelog: - V1: Fixes the penetrator and rectifier. - V2: Also hides the duplicate dubstep gun Installation: Download "fixed_weapon_customisation_and_hide_duplicate_dubstep_gun_v2.zip" and extract the zip file and copy the contents to your Saints Row IV directory -eg: c:\Program Files\Steam\steamapps\common\Saints Row IV. If you're using other mods that use vint_doc_containers.asm_pc, try using ThomasJepp.SaintsRow.Stream2Update.exe from this thread: http://www.saintsrowmods.com/forum/threads/minimauls-saints-row-iv-tools.3188/. Just double click it to run. Notes: If you're having issues with V2 and are not too concerned about the duplicate dubstep gun, please try V1 instead.
