Hey, I figured it out, by removal of the /ini/armor.ini file makes the client not load player models, hope this helps people for when they want to compose.
Cheers
Note: NPC's are still visible, making it possible to see warehouses and interact with the game normally, with invisible players
Edit: after exploring a bit I found that Gem Embed, Bonus Endow, and Level Upgrade npcs data is apparently stored in armor.ini, so these npcs are missing in the game, later when I get back from errands I will make a quick batch file to swap ini files to 'toggle' players on and off (client restart required)
