Never done this before, hope it goes well.
Gonna update this over time for a while, I'm never satisfied and am still finding tweaks I can make. But otherwise this seems like the best possible version.
Oh if you want to see "development" screenshots, I uploaded them all to Imgur here:

Alot of these were meant to be used for the eventual upload, but I realized the HDR_Blooming problem pretty late in. Felt disingenuous to use them.

Installation guide:
~~~~~~~~~~~~~~~~~~
First you need to download Reshade: https://reshade.me/
Next, launch it, click the "Click here to select a game" box, look for eldenring.exe
If eldenring.exe doesn't show, click browse, and navigate to your Elden Ring folder location, and choose eldenring.exe

If you have the game on Steam, you can right click the game, under Manage, and click Browse Local Files. If you see a folder called "Game" enter it. From here, copy eldenring.exe, go back to Reshade, and where it says 'File Name:' at the bottom, paste, and then enter. It'll ask you which rendering API it uses, choose Direct3D 10/11/12

From there, all you need to do is drag and drop the content of "Alive" into the same folder as the .exe, when reshade launches, press Home, there's a tutorial you can follow if you'd like, from there, at the top is a dropdown menu and arrow keys, click the dropdown menu and search for 2023.ini

and bada bing bada boom you're all good to go.
