put TrailThinMkI.tga (texture file) here Mods\vas_White_curving_smoketrail\3Do\Effects\TEXTURES

put TrailThin.eff (effect file) here Mods\vas_White_curving_smoketrail\3Do\Effects\Tracers

I don't have that same file structure in your mod.
I have MODS/vas_curving_Smoktrail/Effects/Materials and SMOKES. Materials contains the TGA file and SMOKES contains the eff file.
How do I find the other files to change the other types of smoke trails and what do I do with them once I find them?
There are a few other items in Il2 that I want to find and try to change, but I do not know how to look for them.
How did you find the files to change the smoke?

I think you have my first version for grey smoke trail, what i wrote was about the white one (in my update) used mostly by italian airplanes and some russian airplanes.
Well if you have extracted (by sfs extractor) all sfs files in your game you should have 90% of
files!
3 files TrailCurved, TrailRicochet and TrailThin.eff , the last one (TrailThin.eff, already changed) is for white trail
inside smokes folder you will find "smokeBlackBulettTrail.eff"(already changed) this one handle grey smoke trail.
TrailCurved handle the corkscrew effect (not changed, ok as it is, i think).
Well, I don't know what do you want to do (changes) you can chang the .tga files and .eff files.
Be aware that some changes you are not allowed to do according site rules for weapon modification.
