Hey guys,
So I was working on a Porsche 911 GT3 997 following the Porsche 911 GT3 RS tutorial, and I was having problems with LuxRender so I decided to use another of the creator’s tutorials for rendering cars with Cycles. Around 27 minutes in the tutorial, I was having several problems.
My first problem was that the car paint material I created (exactly the same as his) does not look like his
Here is the screenshot of my file and the link to the tutorial:
My second problem is that the car does not have the material all over it. I checked, I applied it to all of the vertices and I also checked and it is just one object. There are no duplicates either. I am thoroughly stumped. I would really appreciate the help!! Thanks so much guys

I can upload the file too if you guys need it
