Give 2.2+ a shot.
There's now an option in the Project Settings/HammUEr page to switch UVs between Default (aka half, like it usually is) or Full Precision.
Note that I had to build this with VS2022 because my machine decided to nuke itself last week (like I needed more bullshit, right?) and I had to rebuild my entire system and pipeline from scratch... but Microsoft doesn't offer non-paying VS2019 versions any longer, so I figured I'd give it a shot.
Should be fine, and Works On My Machine™, but... I guess we'll see.
