BTW ! If anyone want to change the color of the camo, is it very simple !
Here the tutorial step by step
1: Get the weapon file u want to change the color (exemple AN94)
Take all files, but the nml or n go directly to the images folder of plutonium, no need to modify it
So u have file like spc, col or 37NCVC98 thing like that
2: Go in photoshop or other application can modificate pictures etc and create a 512x512 
3: Take the color or ur choice ! for the exemple i do this :

4: Save as PNG in the desktop and install the paint.net logiciel to save the png to dds like this

5: After this, dupplicate the image x the number of file for the AN94 (So 2 (3with the nml / n but the nml is in images folder, don't touch him) but some weapon have more, like the lsat 6 or 7 files, so dupplicate 6 or 7 ur colored dds image) Like this :

6: When its done, u just need to swap the name like this : (u can remove the iwi file after swap the name)

if everything is ok u have this :

Now download the application : iwi_dds_fast converter, google it, its very easy to find it.
And u just need to drag and drop ur dds images like this :
