Installation
There are two options available. The first option will mask all lower screen elements (health, armor, blood punch and dash icons). The second option will only mask the health and armor bars.
1. Choose one of the two options available and copy the UIMask.png file in that folder to your game's reshade/textures folder (ex. \DOOMEternal\reshade-shaders\Textures). Overwrite if needed.
2. Run the game and with the ReShade menu open, enable the UIMask_Top and UIMask_Bottom shaders.
3. Click the "Active to Top" button and drag UIMask_Top so it's above UIMask_Bottom.

4. Position any active shaders that you don't want showing on the UI between UIMask_Top and UIMask_Bottom.
Workaround for total screen changes
- Even though UIMask works great on a game like Doom Eternal there are still total screen changes (like a maps or inventory) which can make those screens look difficult to see, depending on how crazy your shader is. My workaround for this is to use ReShade's hotkey assignment option in conjunction with Doom Eternal's hotkey assignments. For example, I've assigned all my shaders to the Tab button which is the same button I have mapped in Doom to bring up the menu. That way when I need to bring up the menu screen the shaders will get disabled automatically and the game will look normal. I just have to remember to hit tab again when I want to return to the game to reenable the shaders.
Extra notes on UIMask
- If you want to create your own UIMask, make sure UIMask.png stays in mono because the areas in black are what cancels out active shaders. Gradients are supported as well in case you need to create a fade effect. UIMask works great on games like Cyberpunk 2077 or Doom Eternal where the UI is fixed, however it isn't a great option for games that have a more dynamic interface, such as Dark Souls with its expanding health and stamina bars or Nier Automata and it's disappearing UI when out of combat.
- You can edit the UIMask.png file and see your changes without needing to restart your game. Just click on the Reload button at the bottom of the ReShade menu once you've updated the png file..
- Here's something neat I learned while messing around in reshade. If you invert the colors on UIMask.png you can create a reverse effect, meaning it will focus a shader's effects on a specific area of the screen as opposed to negating them. Not sure what the utility of this would be or if it has any interesting synergy with other shaders but I'm sure it's out there. Get creative with it!
