Okay, after way waaay too much testing, I can confidently say that the redone textures won't work on v1.2, v1.1, or the v1.0 I've been able to get somewhere just now. That goes for the ones shared by
glassessese and
MartinLutherQueen, on my end.
I don't have the MLQ whole download anymore, but I believe I've been carrying the Bepinex folder from within it bw the versions, and now just tried with the v1.0, and doesn't work - only SW_decensoring.
Or maaaybe it's just the Translation folder that I actually have, and then perhaps the Bepinex/XUAT config files and settings maaaay differ, and that could I guess spell trouble, but I think it was the whole Bepinex folder, hmm...
I would say it's 99,9% for sure not enough to have only the textures folder from MLQ, and 98% not enough to just have her whole BepInEx folder. I can't make any version show up differences, even though I located the (indeed, mostly hand-uncensored) changed assets for the Revenant and Iris's FleshWall ending for comparison.
I can 99,9999% for sure say that glassessese's Bepinex dir won't do the asset decensor bit, tried on all versions (and I've located those very same redrawn assets for these two scenes, so I'm assuming he had all MLQ's modified files as a base and expanded on them, and that's what I believe I'm getting from his post here as well; and these two modified assets files have the same name (checksum) and same modification date, so pretty sure...).
Nope, it's there for the "only SW" as well, but it's present for the vanilla too.
