Thanks! Will rerender when I have a fully detailed interior.

Here's just a little test with the rear lights. Suggestions?

Working on the interior.

Do you guys have any lighting tips for rendering objects by themselves like this? Is there any good pdf lying around somewhere?

Cheers

Most general technique might be 3 point lighting

but all techniques known from product/studio photography will also do the trick.

Thanks, I'll try that techniqe soon - very helpful!

I've been finishing the Koenigsegg, and I've rendered a little closeup. Nothing special - the carbon needs work but I don't know what to do with it. :( Anyway I hope you like it!

(excuse the horrible jpeg compression but the site doesn't let me upload anything else)

The carbon fibre material is an interesting challenge actually, that can't really be done in Indigo efficiently currently.
It really needs a smooth dielectric coating material for the resin, and then a substrate for the carbon fibre with its own shading normal. Currently in Indigo the substrate can't have an independent shading normal. I'll try and improve this at some point.

Exactly! I tried to put a coating layer over galinette's carbon material: http://www.indigorenderer.com/materials/materials/343 but it just turned out plain gray. This one is just a carbon mat with some diffuse, bump and exponent textures on - doesn't look too realistic actually. I'm currently modelling a thin glass layer and will give it a simple specular thansparent mat to simulate a coating over galinette's mat. Being forced to do this on all carbon surfaces on a Koenigsegg (they are many) is a bit of a let-down to be honest. :?

Modelling a specular surface over the top of the carbon fibre will work, it will just render very slowly in some circumstances, such as when the light sources are small. This is because it's a classic SDS (specular diffuse specular) situation.

I'm using a large emitter here, so it wasn't that big of a problem. Here's the finished version.

When do you think this will be available?

Very interesting, Ono!
Nice car and nice renders, Oscar :o .

Will have a look at it after 3.6 is done.

Looking forward to the double normal definition.
A nice option would be an embedded blend parameter for the coating bump between its own and the substrate's. Kind of an integrated finishing feature.

Thanks guys, looking forward to being able to create realistic carbon!

Here's a new render - and I'm showing you a "curved" and an untouched version - C&C appreciated as always! :)
