Airboat's wake VTF and VMT files?

I’ve searched through several GCFs, can’t find the vtf or vmts for it, a pic if you dont know what I’m talking about
And no, its not in materials/models/airboat.

Let me know if you find it’s location, thanks in advance

Actually, i have to wonder if it’s some sort of particle effect, then again, I know its not in the pcfs

iirc its the old hard coded particle effects. Like the grenade smoke effect. Hard Coded.

Ew, that sucks
