Simulating clearcoat?

[steevo]

Could anyone point me to a tutorial on simulating a car's clearcoat paint job?

It's the little flecks and multiple layers that are doing me in ...

Thanks,
Steve

Newtek has some tut's that go into using the "BDSM" shader plugin to have two sets of specularity settings to do what you want.

Or you could model the actual clear coat using some smooth shifts and making the "clear coat" and actual 3d-entity that is "water-tight" then one could assign actual refraction and all other surface attributes to it.

You might want to look into some "classic-LW glass tut's" on how to make an "air" surface with normals facing inward instead of outward to get internal bouncing of the light rays - That is if you go with the modeling method...

I'm sure that glassefx means the BRDF shader (31.60 lw manual)

also

as you'll find one of the best car tuts out there

Thanks, gents! The BRDF shader didn't really do it for me until I brought down the diffuse value. That made it work nicely, giving a metallic look to the undercoat.

Modelling the clearcoat with smooth shifts is a good idea too, and I'll give that one a shot when I have some time to finesse this.

Damn fine Mustang tutorial. Very nice.

Thanks again,
Steve
