I needed a gas mask overlay script for a MP mission I'm making. Unfortunately, I couldn't find anything that works across respawns... so I modified the overlay part of the script made by ALIAS - "Radiation - DEMO", after heavy modification the overlay is now MP compatible.
There are currently some issues, which I hope I can resolve in near future:
* Gas mask overlay will remain after respawn until the player equips and then unequips the "Gas mask"
* For some reason the script doesn't work with the "Contact DLC" gas masks. It actually works. It appears the unit (cbrn_specialist) spawns with "G_AirPurifyingRespirator_01_nofilter_F" and later respawns with "G_AirPurifyingRespirator_01_F", keep that in mind.
Feel free to contribute, I'm stuck as it is.
I'll provide further updates in the github repository
Modified multiplayer compatible overlay script.
