I tried to rig those weapons like i rig any weapon, stuff from other games like advanced warfare and rainbow six siege came out fine, but anything from any battlefield game (3,4 or hardline) comes out like this when i try to attach it to the weapon rig....
I used the same method to rig this- http://www.youtube.com/watch?v=ogdpP-LtWHE&feature=youtu.be and it worked perfectly

Can anyone help me?

I have some problems with my map.
One of the major problems is the textures randomly becoming all shiny for no reason.

I installed tom's music box too, but since i have done that there is a huge console spam from

clientscripts/music.csc

Can anyone help me?

I wanted to create a simple custom map, but i didn't really understand how to do one.
I installed the modtools+ugx patch, then converted with launcher.exe.
To use the UGX script placer 2.0 i need to create the map with radiant first and then select it later?

And how do i add custom guns? I already have the required files, but i didn't understand if i can add ALL of the guns i want in the /raw folder, and then put in the map the ones i need, or if i must put ONLY the guns i will add to the map.
