UDK - Car paint mateiral

MikeFriel · May 2014

Hello all,

I'm currently creating a car paint material in UDK, in my current setup im using a Fresnel multiplied by a constant to create some dark rim lighting, the only problem is that I don't have much control over the Fresnel falloff, once I've increased the value past '1' I start to get a hard edge (Image below).

Does anyone know of a setup where we could control the Fresnel falloff?

Help would be much apprecaited.

Thanks
Mike

Fresnel doesn't work well above 1.

Try to keep it below it should work, I made this effect in UE4 and I got .2 or .3 to work best for the exponent.

Ah, yea that helped a lot doesn't leave you with much control but it looks much nicer none the less.

How did you go about the pearl/noise coating? I've added noise but I find that if I raise the influence too much it tends to brighten the material, I'm wondering if I've got the setup wrong :S

Anyways here's a screen shot of my car paint material thus far, would appreciate any critique or tips on how I can improve...

Zac that was in UE4, he is currently working in UDK.

I know there is some stuff that has been made before but I can't find specificly what I was looking for. I just moved so I dont have my comp with UDK up but I think I might be able to help.

Thanks Shift that would be great any help is much appreciated

I think I'm getting there with the car paint material its not looking to bad atm, just something not quite right not sure what though... From the examples I've seen on the net it definitely can be improved.
