I found it is possible to change the player's outfit to Video Repair by using "customization_outfit_wear" command via sr2_city.lua (this feature might be included in the future versions of my Sandbox++ mod):
I could not find a way to activate the wardrobe UI from lua though.
Code:
-- Video Repair outfit
customization_outfit_wear( "repair", 0, SYNC_LOCAL )
if COOP_COMMANDS_ACTIVE then
customization_outfit_wear( "repair", 0, SYNC_REMOTE )
end
sandbox_message("Video Repair Outfit activated")
reset_input_sequence()
