I just figure it out like a hr ago
Raybullet is found in Common3 pac > ef_common > Model data 30
You gotta do some hexing with the mdl0 file of the EffCommonRayGunBullet so export it as a mdl0
Now if you look to the right u see ARGB pixel array those are the variables that need to be change
so now you load the mdl0 file into the hex editor.
Yellow Color coded is where the lines start
Tama_Main
00001B20 - RayGun Laser Color data
TamaFlare_flare
00001B60 - RayGun Flare(This is the color of the aura around the Lazur)
Blue/Red color coded - these are the values in the ARGB color array in the same order
the difference is that instead of Alpha being the first variable its actually the last
each value is of RGBA is based on the 0-255 scale you just have to convert the number you want into hex
Example for the first one on 00001B20(Tama_Main)
R(Red) G(Green) B(Blue) A(Alpha - same thing as transparency)
FF FF FF FF
this method will also work with other things as well
