I've made a gun on Slab 6, How do I get it so I can play with it on AoS?

Well... assuming you did everything correctly you'd probably save it as a KV6 file into the KV6 folder in the Ace of Spades program folder. Rename it as the model you are trying to replace.

I saved it as KV6, I put in the KV6 folder in the AoS program folder and what do I rename?

Semi.kv6 for rifle
smg.kv6 for smg
shotgun.kv6 for shotgun

do i have to replace a gun, or can i replace something else, also, if i edit playerdead, will that be me dead?

also, how do i change my profile pic?

and how do i get ironsights?

You just started didnt you?

1. Yes, you replace guns. Playerdead is player model that is dead (got shot).
2. Gravatar.com
3. Ironsights are png files located at your game directory PNG folder.

also, if I replaced a gun would just be that orig. gun? also do other people see my gun skins and playerdead skins, or do i just see them?

also, I can't modify the ironsights can I?

sure you can. it's just a PNG file with an alpha channel for transparency. GIMP or photoshop. people have done lots of stuff with all of this. Have you considered using the search button?
