Re: what would be the best way to get this effect?
i could quote myself, but i won't - this would be the way to go if you want it to look somewhat correctly, you'd have to build you own custum shading network and use different normalmaps for the coating (specular shading or reflection) and for the kevlar (diffuse shading). its somewhat memory intensive though. so maybe… -
Re: what would be the best way to get this effect?
I think folks might be over-thinking this. Diffuse + Normal + Specular + Cubemap. Done! -
Re: what would be the best way to get this effect?
you could use a different normalmap for the diffuse (underlay) and one without the detail for the specular/reflection (coating) -
Re: what would be the best way to get this effect?
You could fake the bumpy Kevlar in the diffuse and then use a smooth shiny norm/spec Probly Wouldn't look too hot though.... -
Re: what would be the best way to get this effect?
If you've got enough geometry to split materials you could go for a large texture for the normal map, and small tiling textures for the diffuse and spec. -
Re: what would be the best way to get this effect?
Thats the trick - even tho it looks like it, you really don't need a normalmap at all for the small tileable pattern. Just diffuse and spec is enough. Then, the normals on top for the big smooth glossy shape. -
Re: what would be the best way to get this effect?
I think mbullister's example shows that a multilayered surface does look much better and more realistic than just diffuse with a flat normal. Sure its more expensive, but thats what fallbacks are for. Having the extra specular layer really helps the perception of the material. On a side note, with unreal moving to deferred… -
Re: what would be the best way to get this effect?
If it's just the raw carbon weave, then you can do it easily, with the carbon's normals, low (really low, like a matte finish) spec and a diffuse. For the coated carbon, the clearcoat has to be it's own geometry. Sorry, but for the good results you're going to have to do the carbon normally, then another mesh .1cm above… -
Re: what would be the best way to get this effect?
I've done this with a painted diffuse/spec of the weave pattern, and then a cube map on top. The normals did not have the weave pattern in them, just the normal shapes. If I'm going to eye-fuck it as an FPS weapon I would want a custom shader, but if each ribbon of the weave isn't going to take up more than 1-2 pixels in… -
Re: what would be the best way to get this effect?
I've done this before but to save memory and the extra texture call, the cubemap UVs were driven by the vertex normal so the reflection itself was smooth (though of course your geometry would have to be dense enough to support this). Either way, it's pretty much what mbullister suggested; You need the reflection to have a…
