I wanna have a go I'm trying not to find out how to do it myself ... I have 0 Photoshop skills and it takes sooooooooo much time for me to edit skins etc.
There's a file on my OneDrive that changes the mask name to Lando file = "UIMask.png" swap it out with the one in the Reshade textures folder.
Reshade Changelog 6.1.0: Features: Added builtin add-on that synchronizes preset between effect runtime instances/windows (this is enabled in VR by default, so that changes in the desktop window are automatically synchronized to VR)
