Metallic Car Paint shader for Blender (Cycles and Eevee) 

Good to know! I almost wholly use Cycles but I've pinned your comment for any future Eevee users.

Thank you, I'm glad you found it useful.

Glad you found it useful.

Thank you.

It's Driving school from PolyHaven.

Thank you. Clearcoat thickness is certainly something that is real but on most cars it's measure in the 50-200 micron range so it raises an interesting question of when is close enough close enough? As far as I know, the only way to really get thickness for a clearcoat would be to duplicate and scale up your mess a tiny tiny percentage and adding a glossy surface and volumetric to this. But you couldn't add regular Blender materials as Blender breaks some laws of physics when it comes to energy conversion of light passing through objects. If you're going to this nth degree, would you also model the various layers for metallic flakes as they're at slightly different levels too? This all probably could be done using the real physics equations and enough math nodes but I'm not sure how much better it would look or how much worse render times would be. That said though, it would be an interesting challenge to try one day. As for the metallic value, I'd agree. In theory to be correct the metallic value should only be 0 or 1. Honestly though, similar to above, it took about 2 weeks of tweaking to get this material and it got close enough. But maybe if I fancy chasing the clearcoat above, I'll chase the perfect base too.

How do you mean 'a simulator asset'? Existing UV's shouldn't matter though you would need to add something like alpha masking if you want to mix between my material and an existing UV map. As for existing texture/roughness/normal sets, it would again depend how you mean it. As if you're wholly changing material I'm struggling to think of a reason you'd be wanting to keep using existing sets.

@@AutEmotiveDesigns There are lots of others textures for other parts that shares the same UV’s Texture map. I’m guessing I need to learn/figure out how to bake all of the individual components textures at the same time. If I try to bake this effect, that is all that ends up bake, everything else is missing.

I just loaded the MX5 used in this video in 3.3.1 and it renders the same so don't see why it looks different for you. I'm not sure what you mean by mirror vs paint camo pattern so I can only assume you've gotten a node or setting incorrect somewhere. Send me an email to my email address in the description and I'll send you a file with the material so you can append it to your project to make sure it's the same.

@@AutEmotiveDesigns _"so I can only assume you've gotten a node or setting incorrect somewhere",_ that is very likely (and maybe like 1pct chance that my model-scale doesn't play well with some of the Scale values used in some of the nodes) thank you sir, i will 👍🏻

forgot to add a follow-up here, in case anyone stumbles on this too thanks again to the channel owner, in the end we found out I had normals flipped on the model

Thank you for the kind words. I have a good mic, I'm just struggling to find a good consistent set up with it but I'll get there.

Glad you like it. My instagram and email are in the about section on my channel page.

i think it should be left side so we are staying out stay out in in in lapd cars to overtake the safety car this race that started with i dunno what is ended with i dunno what

I hope it will help you
