Octane car paint shader

[Kerem]

hey guys, this is my latest render ( just the render, almost beauty pass.)

I would like you guys to take a look and tell me what is off? ( if so)
I know about the chrome parts reflectin is busy, and the car shader is maybe not there.. i have tried a couple versions but i would appreciate it if anyone stood up said "hey dummy you're doing the car paint wrong"

First it was a crazy set up with almost 7 mix materials and i have "sensed" something was not right.. now just as the contrast.. i only have one material and that is glossy.. maybe i should pick a road between the two ends..

Any help appreciated..

Settings:

this is a quick render 800 passses PT. i'm using a 980 and a 780 2.22. version. Lighting is done by the hdr light studio 4 i highly recommend it and also i got the Hdr and the backplate from Dosch.

You actually just need 3 Materials:

1. Base Color (Glossy Mat)

- Spec will be your carpaint color / Diffusecolor can help to give the car some depth
- Roughness can range from 0.3 to 0.6/7 depending on how metallic the carpaint should appear
- And the index should be turned all the way up to 8 to make it a metal variant

2. Clearcoat (Glossy Mat)

- 0 diffuse
- spec 1 (or slightly less if you want to make it less reflective)
- index somewhere around 1.7

3. Mix Material

-Base in Material2 slot
-CLearcoat in Material1 slot
-float texture regulates on how reflective or metallic your car will appear


Of course you can change the settings here and there (unicolor or metallic carpaint etc..), but this should give you a good looking base materialmix.

Very nice help sir, any advice on how to do the grain of the classic metal car paint?

Very nice help sir works a charm, any advice on how to do the grain of the classic metal car paint?(i my image the grain is due to the render low samples)
