The file name is env.int!
First of all you need to download this application, called L2FileEdit.
After you downloaded it, open start it and open the file named env.int located in your SYSTEM folder, inside your Lineage 2 game directory.
Scroll down untill you find the lines:
EnchantMeshShow=4
EnchantEffectShow=4
Enchant0=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant1=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant2=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant3=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
EnchantMeshShow=4
EnchantEffectShow=4
Enchant0=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant1=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant2=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
Enchant3=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1)
EnchantMeshShow=x --x is the enchant number at which colors start to show up (in my case i`ve set it 4, so at +4 enchant colors show up, but you can set it any value, even 3 or lower, doesen`t matter)
EnchantEffectShow=y is the + at which flames/Epic glow show up (EnchantEffectShow is set to 7 at to show the epic glow at +7 on Titan/Theoi weapons as default, i`ve set it at 4)
and the enchant lines continue... The ideea is that every line is an enchant property on the weapon. FOr example Enchant3=(R1=0,G1=10,B1=20,R2=0,G2=0,B2=30,Opacity=0.1,Num=0.1) is the weapons property when enchanted at +3.
NOTE:
EnchantMeshShow=x --x is the enchant number at which colors start to show up (in my case i`ve set it 4, so at +4 enchant colors show up, but you can set it any value, even 3 or lower, doesen`t matter)
EnchantEffectShow=y is the + at which flames/Epic glow show up (EnchantEffectShow is set to 7 at to show the epic glow at +7 on Titan/Theoi weapons as default, i`ve set it at 4)
How to Change the Color of the Glow
Now that you have opened the file and understood what we must focus on, we can start editing the color of the glow.
For Example, let`se see a +14 enchanted weapons properties :
Enchant14=(R1=0,G1=30,B1=240,R2=0,G2=41,B2=200,Opacity=1,Num=1)
The Glow in Lineage 2 is made up from the combination of 3 colors: Red, Green and Blue. By Modifying these values you can obtain your desired glow effect.
