I don't know how you got it so quick, it took me about 10 hours. I noticed that you CAN'T USE THE SAME SHAPE. You do not get uses! You need a BRAND NEW shape for it to count as a use! Maybe I did something wrong on my end so it wasn't working or Forza patched that method, but this is what I'm doing. I already had a lot of shapes, but I decided to start from scratch. Make 250 shapes first naming them 1-250. I used a keyboard on pc, just saving the exact same shape and naming it something else. I added a description to sort them easier as well. Boot up 2 alt accounts, go to apply vinyl shape and search up your main account's 1-250 shapes. keep adding your shapes and all of the shapes should be added to your "my vinyl groups". Double check that these are being added there. Once you download all the shapes on the alts, apply them to the car. That gets you half way. Sign back into your main account to make sure the uses are counted. You should be at 500. Next make another 250 shapes naming them 251-500. Then boot the 2 alts back up and delete all the shapes you downloaded previously so you have space for the new shapes because of storage limitations. Now search up your shapes 251-500. Download them and apply to the car. Hopefully my method can help some people, but this probably is not the beast because OP got it in way quicker than me. I just ran Forza in a window and watched YouTube while I did it. I did this similar strategy with paints so I'm used to this. My last couple accolades are open drifting event win and the upcoming new years A38 lantern smashing. Good luck out there.
