Doing some derusting and learning the new Any% strats.
I've replicated both Extodasher and Azorae's runs (oob trigger and QR code) and I can't get paint to spawn in A6.
Is it only a chance that paint will spawn in A6 or am I doing something wrong?

Not playing on modded version.

Current theory is that you need a save file with QR Reader and Good Listener unlocked in order to get those triggers.

Update:
I went with darkid's theory and spent some time unlocking the QR Reader and Good Listener achievements (which I didn't have before) and I can confirm that this solved it.
Paint now spawns for me in A6 for Any% after completing the 5 message triggers.

Thanks for that!

Sorry for a necro, but I'm having a similar problem and I didn't think I should make a new topic. I'm also not able to get the QR message ("I am not the first etc."), even though I went and got Good Listener earlier today and I already had QR Reader from my first playthrough. No matter which or how many QR codes I scanned, I couldn't get that message. So with nothing working, I though I'd reset the QR Reader achievment with Steam Achievement Manager and just get it again, but it gave it to me upon restarting the game, so I don't quite know what to do.

EDIT: Theos helped me get it, turns out I just needed it on my current save file 😕 what a dummy I am
