Hello guys! i really want to know how to do window stickers!
if someone has a template or a done .dll file with stickers on send me that please!
it should be very very Thankfully!!

You can't.

UFR, XFR, FXR, XRR and FZR can have small stickers on the very top of the windshield. This does not require editing .DDS files as the windshield stickers are part of the .JPG skin file. However, you need to have at least an S2 license to drive those cars.

The 'stickers' can be edited - they are in fact, the same as your chosen number plate.
Options/Driver/Number plate



You are restricted to about 8 characters, and they will only show white on the window.

for a second I thought you were speaking about real world LFS stickers
