Hi Jineh, I used that same link above and found that the tray files did not work as previously mentioned. After a lengthy search I was able to locate the cube studio on on the gallery while in game. It's called Cube Studio renovado and was uploaded by EA id: KMinAh29.
Hope this helps!
I cant find this on the gallery do you have the tray files to it? I really need it. If you have it in ur game please put the tray files on a google drive or mega file or something.
Tutorial to do so :
Open your lot in a new save file.
Save your lot to your library from Build Mode (folder icon at the top, then little house icon) and note the time that you did so.
Go to your \Documents\Electronic Arts\The Sims 4\Tray folder and click “Date Modified” to sort all of the files by time and date, grouping the most recent at the top.
Select all of the files that have the same timestamp and copy them to another folder (I have one just for saved lots, where each lot has its own subfolder).
Of the files you copied, you should have at least one “Blueprint” file, one “Trayitem” file and several “BPI” files.
Use an archiver like WinRAR to zip the files together in the folder and make the .rar or .zip file.
