@stillhere So will the .png's be stretched to fit the screen or will their position, length and width be adjustable in-game?

I think it looks like it's ready to be uploaded.

@stillhere So will you be able to add images into the script like DECAL5? Never mind, that's an irrelevant question.

@stillhere If I could extract files from different games easily, then I'd do it and post some here. But all I can find right now is Google images. I also found a blood on screen effect, if that works too.

I searched around a bit more, and so I found this as well.

I also think that mask textures from games like SWAT 4 and DayZ would work as well, since they're transparent in view. Just search up on Google "First Person Mask
or "First Person Helmet" and you'll find some good images. It won't let me post any here, unfortunately.

@stillhere Maybe you could add a blinking effect to it. An eye blinking png image.
Like this, but less complicated and simply an image instead of an animation.

I'd be grateful if someone made a mod about importable .png images that can be toggled on and off with just a simple .dll script. This would work much like the helmet/mask textures when switching to first person mode.

This may take longer than expected as I have forgotten my Social Club password the day I created my account.

Okay, I'll try this.
