remove the 'on fire' animation from view when on fire

hello, id like to request that someone either point me to where its been done or be so kind as to inform me how to do it, to remove the fire animation that obstructs your view/screen when you catch fire,

the reason i ask is simply i am spending alot of time on fire and am very tired of it making it so hard to see, i have tried optifine but all it does is replace the animated obstruction with a new obstruction that is not animated yet equaly obstructing, id like to be able to see clearly even when on fire,


i am spending many hours playing on a new server that makes use of the heros plugin and my particular class is immune to fire or lava yet i still see it in my face when im lit, and it is very very annoying when it doesnt kill you, cause it just blinds you for many minutes, particularly unfair when your specific skill set is supposed to regard traversing lava what good is it if it makes you blind?

i checked terrian.png and particles.png but now ive read somewhere that the fire animation is actualy only a result of coding, so just which class file is it that this coding is contained in?
