I found a bug with the glass textures. When looking at two stickers, the one that's further shows through the one that's closer (the black and yellow one is on the rear window and the red and white one is the front window). When looking from the front, it's the same - the rear one shines through. It's like the glass texture is inside out or somethingView attachment 279406
Thanks for the report, but as I say previously, we are not able to rework the 3d model.
