when I want to use it he keeps on taking it on and off constantly

You need to have another weapon in your inventory. The PES switches to your last weapon when the animation is done. I will add this to a FAQ that I'm working on.

add an animation in third person

Third person animations are a pretty difficult thing to make, as they override the default Valve Skeleton animations for players. And i don't even know how to do it.

Okay then, I'll put this on the bug/glitch discussion. When equipping the helmet, it is completely invisible in my hands but completely visible on the my head. There is a small black dot that I can see during the animation but it is very minute and hard to see let alone notice.

Ummm, There's no Gas Mask tab

@zacgamer777 You didn't let the mod load. Restart the game.

@TheChemicalReaction Once again, i must ask if anybody else is having the same issue. I need to be sure if it's an issue with your game or my addon.

why do i still die in nerve gas?

btw i dont have chemicalreaction's issue its probably one of his mods.

This "Nerve gas" must be dealing a form of damage that is, ironically, not DMG_NERVEGAS. I'll look into that in a few hours.

thx man

The mask is an error sign and there is no animation. Plz help

@mr.pengi just re-install the addon

Btw hidden it's the M9K nerve gas.
