Wow, good start, but the background is too dark

In the first picture, there's a white rectangular on the driver's side. What is it?
A reflection of your emitter?

A nice modeling job, BTW :D

The modeling is excellent, but the picture is underexposed. You just need a bit of tonemapping.

The fact that the bottom of the car is more diffuse than the upper catches my eye.

There's a vent there made of chrome, so the only thing for it to reflect is the emitter.

What would you have done for tonemapping?
I used linear, with scale 250, 10^1

I for one would have changed the lighting... I'm sorry I didn't see that clearly earlier in you wip, but your model would be in much better shape imo in a "show-room" environment. That would be: arrays of lights on the ceiling, and a wide opening toward exterior (biiig mesh emiter but much dimmer than direct sunlight).

The lights are actually too small and fail to pull the shape out of shadows. Sorry that's harsh :/

I must add that the modeling is great and the renders clean :?

I don't really get the setup you're describing. Can you post a picture or a file or something.

Oki as a starting point you can use this texture for the ceiling's emission:

*edit: awoops bitdepth is wrong, needs conversion :mrgreen: ah no it has an alpha layer :oops:

I'm editing mats by hand, I didn't do such emiters since I stopped using mental ray and final gather.

** no way I've got a luminance() unhandled error trying with textures, even jpg :(

I'll try another approach, a box with openings and sun or uniform background. Sounds bad but could do.

I was refering about someting like that image, exit portals are underlined. Designed to work wih either sun, background or env map.

Of course you can do the same with simple emitters, the point is to recreate a common environment, where we are used to see cars I guess. Finally nevermind, that was just me :/

No, I like where it's going. I just need to spend more time it. I'll move this back to wip.

hmmm, any idea where exactly to find it? I searched for a while, but didn't find anything.

The final hi-res looks great. It's now one of the site banners.

Looks great :D
But the tires are somehow too perfect... They don't look like the car really stands on them (they're not flattened) and the sides are too flat. The profile is nice :)

Else, it's perfect, I'd say! The tires REALLY are the only thing to work on, a bit...
