Need help for the 4th piece of polaroid !

It's the one where you get coordinate when you get out of the clan void dimension and it doesn't trigger.
I'm kind of late in my survival wolrd (around day 80) so I might have missed it but it's kind of a bummer if I already got it and miss it.

For now I'm just torching the layer at Y 232 to see if I can get it by chance but so far, nothing.

I don't know if it needs spoiler or not.
