Not a lot of progress this weekend. I was meaning to do lots but then mental ray decided to not render the exhausts' material like it used to. No idea what happened to it. So I made test with the chrome material applying it to different objects around the car and it seems only the exhausts render wrong. It just wouldn't render shadow inside the exhaust pipe like it used to.
See how the body and the exhausts look like they are different materials altough they are the same!
So I ended up making a new chrome material using a more simple shader. Now it gives me sharp and strong reflections with proper shadow inside and as a bonus it renders a lot faster than the previous material too! I did try another proper chrome shader but that thing multiplied the render times and didn't really give any better results.
I also made mesh patterns for the holes in the body kit.
And found a glare effect for the camera.
