I was unsure of the right search terms to put in, so I decided to post this.
I'm trying to add some effects to gas masks and eyewear in my mod to make them feel better. I've already figured out how to use imagespace modifiers to add simple tweaks, but I want to add dark edges to the screen to better simulate the constrained field of view. I can only find blurring effects and screen-tinting stuff in IMODs, so I decided to ask here.
Does anyone know how to apply a texture to the player's view?
