layered shader? for metallic paint

Hi there,

Firstly I've just downloaded the demo version of Octane and I'm pretty impressed with what it can do!
I'm looking to create a metallic paint shader which would usually require a layered shader consisting of a base coat with a blurred reflection and a second layer (laquer coat) to create the sharp relflection and highlights over the top.
Having looked through the gallery images I see there is an apparent lack of metalic paint in there.
I understand that this software is at a very early stages so this type of shader probably hasn't been setup yet but I just wanted to make sure I hadn't missed something.

Many thanks

Sorta doable with a mix material. one glossy and other non-so glossy. Try it'll look pretty good

The octanelive livedb has a whole series of carpaint shaders, using the technique described by proupin above,
although it's not available in the demo version, only in the commercial.

That's good news! looks like I'll have to invest in a commercial copy then.
I also quickly looked at setting up some fresnel ramps with the gradients but could find any input for incidence,
I'm sure it's in there but just thought I'd ask while I've got the man on the line.

cheers

Physically based renderers use correct models instead of manual tricks like fresnel ramps...
It's not supported currently.

Thanks Radiance!

That was my misunderstanding, that's good news as it seriously cuts down shader set up time!

Many thanks

Where are these car paint shaders in the live DB? I don't see any of them

Wow, I don't know how I missed those lol. They work great, and were basically the same thing I found worked well in my own testing. Thanks for helpin a noob :)
