Hi all,

I'm currently trying to create a matt carpaint finish for a small personal project I'm working on. My only experience with car paint so far has been using the car paint node, and while for typical car paint the effects this node alone can provide are excellent, when aiming for a matt finish there are some small niggles.

The main issue I have is reflection, the effect I am going after has very little reflection (if any) on it and yet the car paint node lacks any reflection otions apart from the stadnard enviroment options.

The look I am going for is:

So far I have't been able to attain this finish no matter what I try. I'm relatively new to realistic surfacing and thus any guidance/assistance would be a great help.

Scouring the internet for presets has failed to find anything that can fill the gap, for me to use or simply learn from.

Thanks for any help you can give me,

Rainmaker.

I'm not a car dude, but that gives me a bo**r. Where are the missiles?
For sure you will find lots of assistance for that beauty.

Thanks for sharing.
Cheers

Edit: the first image appears to be broken on my end.

Sure looks like a B2 Bomber dosen't it? Was the inspiration for its design. You should see the dash:

Just attempting to re-create its beauty in LW!

Edit: Yeah that image is dead for me now too. Deleting the link. The cars a Lamborghini Reventón if anyone wants to look it up.

Have you tried increasing the reflection blur?

you might try lowering the percentage of the "paint < - > clearcoat", maybe ~20% or less?
(or plug a fresnel into that for your number, maybe an IOR of 1.2-2 or so might look right?)

Remember that you can add another nodes and plug them in CarpaintNode inputs ;).

But yes as other suggested you need to blurry (make it rough) reflections. It HAS reflections (otherwise you wouldn't even see it, it would be completely stealth if is not reflecting light ;)) but it's rough/blurry.

There's a really useful Carpaint explanation from a LALW meeting here:

the quality is awful but if you squint you can just about make out what's going on!

Thanks for your help guys.

It seems the reflection on the node is controlled by its specularity, redcuing that reduces the reflections considerably.

I'm going to play around with it and see if I can achive the desired effect. I'll post the results here if it works, and inquire more if it dosen't!

Thanks for your help so far!

Cheers for that raw-m! Finding in depth tutorials is always fantastic as it's much better to learn the solutions than be told. I'm sure that'll help me in the future.

EDIT2: Wow, I must say 30 seconds in and the wood created with the car paint node looks great and is something I definitely wouldn't have considered using it for.

EDIT3: Point proven, in the video he says paint specularity is badly named and should be called paint reflection. This is the setting I need to fiddle with to get my desired result!

I used a lot of reflection blur in this image and very soft speculars.

Wow that is amazing, you've got the look spot on.

I'm still adjusting the node, can't quite achieve that precise look so far.

After a lot of testing I still can't quite nail it.

Did you use the car paint node for that amazing paint job? I haven't quite got the eye for realistic surfacing yet, so far I've been learning through deconstructing presets.

You can't use the carpaint shader for this kind of pain. The carpaint shader is designed for metallic looking things. I added the surface I used in the render as an attachment so you can take a look at it. It a really simple setup. ;)

Thanks a lot 3DGFXStudios, I did assume when I started out that Carpaint wouldn't quite cut it, but its what I'm most experienced in and thus was too stuck on following that route!

That surface preset really looks fantastic, I really appriciate you uploading it. Now I've just got to pull it apart and learn from how it works!

Thanks again for everyones quick replies, you really make learning Lightwave alot easier and enjoyable!
