Maquette

So try to put the ticket in normal size and then make it small so the achievement skips

This one also glitched on me, loaded the maquette lvl again (chapter select), grabbed the red box and put it outside the maquette on the floor and it popped.

I've tried with the Red cube, the Bridge and the Golden ticket. I've got 100% besides this achv, so I've done every level at least twice, sometimes more than twice. But still nothing. :( This was such a great game, loved the puzzles and the STORY was amazing. But glitched achvs really ruin an experience. Hopefully I can delete my data and start over - and it will pop... fingers crossed...

Ticket method worked for me when I didn't get it on my initial play through.

I tried doing this offline with a new save and also I tried the red cube trick. no luck getting it to pop for me unfortunately

@xVillun Thanks a lot, i've tried so many things without success and your method works like a charm !

I had to delete all game save data, then restarted from scratch. Did the bridge, nothing. Did the red cube nothing.

It popped on the golden ticket. But what I did was use the 'big' ticket to try and open the gate - obviously it doesn't work.
Then shrank it and tried again, and it worked.

Whether or not trying it big first helped, I dunno. But that's what I did.

I had done it before as well, but I think the combo of deleting game save and trying again got it to pop. Finally.

SUCH A GREAT GAME, honestly. Elden Ring and Maquette are the best games I played all year!

Thanks Sarge, red cube did the trick.

Had same issue but can confirm xVillun's method worked for me.

I took the advice from a random youtube video that said not to skip the cutscene beforehand to unlock this. Worked as soon as I moved the red cube afterwards.

Thank you @xVillun i was so worried when nothing else worked!

Had some really strange achievement issues with this game. This one didn't unlock no matter what I did and I finished the entire game. After hard rebooting my console and reloading the second level, this immediately unlocked by taking the red cube outside of the central maquette area and essentially shrinking it. Just picking it up and dropping it didn't work for me. Weird stuff...

I got the achievement by putting the key down for the first time, after which I picked up the cube. I then left the game running while I went outside for a smoke. It popped when I came back. Just waiting seemed to do the trick.

Thank you Villun for that tip. Nothing else was working.

Thanks xVillun!

First comment by wildest worked perfectly for me after it not unlocking.

@xVillun many thanks

@Loxim your method worked perfectly. I booted up 'The Maquette', let the cutscene play out in full and when I moved the red block outside, it popped! Thank you very much.

I just popped this today by using this method:

When grabbing the golden ticket, I walked around for around 20 seconds with the larger ticket then dropped it.

When I grabbed the smaller ticket I then stood on top of the miniature maquette and held the ticket in front of me trying to fit it in the smaller gate where the ticket goes. Do not drop the ticket just hold it in front by pressing B and then after 5/10 seconds press X to hold it.

My achievement popped as I was then taking the ticket to the regular size gate.

Hope it helps.
