I was already asked several times and I also saw a thread asking for the mask view, therefore I decided to open this thread.
The Gasmask mod is giving the gasmask view to the actor.
This mini mod contains mask views for the different suites. Also there are 3 types of removable masks. To use the removable masks you have to add them to the trader files.
There is also a damage model attached to the masks with 6 damage states.
If you want to use it in your own mod, feel free to use it, but don't forget me.
