I modeled this car for fun, at least we thought to use it for some promotion of our company. I'm going to complete other images with all the members of our company as we were the members of a real racing team.
The first image is created for surfacing and generic lightning setup, with a free hdri image. The 2nd and the 3rd are composed over a photo with a hdri map taken from the place where I shot the photo.
All the images are created with Lightwave 7.5 without radiosity, only with 2 lights, the Hdri images are created with free sw HdrShop.
Crits are welcome, bye all

Good job! :buttrock:

Clean mesh and good composition and all, but that spotty texture doesn't quite look good on that car ;)

11-14-2003, 04:00 PM
The 2nd and the 3rd image have been replaced, because of an error on a light setup.
Those points on the texture were a kind of starfield with a glow similar to the one on the logo. I heard some negative feed back online about that, my chiefs liked that, but now I think I'll try some other solutions.

I like the model but, im not feeling the car paint. I'll wait for the other composition with the team for more crits.

I agree, the paint isn't the right one.... Maybe a pure complete red or black with text in a matching color would do wonders... Good model :thumbsup:

I agree with what has been said. It's a great model, but the white dots on the texture doesn't make it right.
Cool compositing btw.
See you.

Cool Cool Cool
What a cool car

Good Carpaint !!

Cool job man!

Could you give any tips on how to make the car look realistic? I'm modelling a Murcielago and I need to make it look real...

It's all about good materials and good lighting.
It sometimes happens too, that one's model is so-so but actually looks great on the render with helps of materials and lighting :p

I like your texture, looks cool :)

Hi guys, thnx all for the critics. I was out this week end, so I'll read soon all your posts, I'm going to post a new verion of the car.

11-17-2003, 08:49 AM
this is pretty cool car!! two thumbs up.
i have a question for ya.
how and where did you use HDR images for your car?
did you use the HDR image which is created by HDRShop for the colour map of your car?
i'm now soooooooooointo HDRI. but, i dont understand
how i can apply and use it and where i put HDRI image
in my scene.

what's trick?? plz answer the question..i'm dying...

Hi Hackie,
this is the process I use.

First of all, I need three or more images with a spherical environment of the backgroung taken with different exposure time, for example 1/250 - 1/15 - 1".
When you open Hdr shop load the images and export the result as radiance (.hdr).
The following step depends of your software, I use Lightwave and the only thing I have to do is to load the .hdr image and set it as Texture Environment. At this point all reflecting surfaces will reflect correctly the environment and if I set radiosity, the Global Illumination will match the same of the background.
The color of the car is independent from the reflections, I have only to choose if the surface will reflect the background, a sferical map, with or without raytracing.

Hope it will be useful, if you have any questions ask me, bye.

p.s. I'm finishing the interiors of the backlights, I guess they don't look real, hope to post new images this afternoon.

thnx Rossifumi for your kind and sweet answer!!
now i get the picture!!!! sweet.
you gave me pretty good idea i can start with..awesome!!!!
thnx agian!!

*ps. it's just extra small question.. when you took pictures
did you use "specail tool - like LightProbe" or...just normal
camera? i'm just curious...cuz..i heard HDRI requires special
gadget...am i right?

11-17-2003, 12:10 PM
Yeah, you're right. For a good result you need a Fisheye lens close to 180° angle or a similar optional. When you have your picture, you may need to unwrap as you need in your 3d software.
I use a Nikon 995 with a wide angle adapter. Usually I mount the camera on a tripod and shot the photos with a fixed rotation with an option to take different exposures with one shot.
At least I create the final map with a photo retouch program.
If I had a Fish eye converter I would make the map a single pass :cry:

11-17-2003, 12:27 PM
ah!! you are a cool man, Rossifumi!!
your answer is just as fast as lightening.
now i got it!!
so..all i need is several fisheyed pictures which vary with different exposures, huh?
it sounds like pain in the neck to take fisheyed pictures...oooooo
thnx again!
and have a good day, man!!
you are the man :bowdown:

Here's the new carpaint! Hope you like it, i don't have much time to update the backlights today, I'll update as soon as possible!


11-18-2003, 08:53 AM
The last 2 images have been updated, I changed some geometry and surface on the front and backlights.
Here are 2 new images, on the back of the first car there are some other dtm teams, I'm thinking to change the ambient with a city street, I'd like to know what you think about.

11-18-2003, 11:02 AM
I was kinda hoping you would share the settings you used, you know?

I'm kind of in a hurry and still fighting with Lightwave. So far, it's winning....


11-18-2003, 11:28 AM
really good modelling but texturing has to be adjusted a bit

anyways, great work!:thumbsup:

11-18-2003, 02:12 PM
Here are 2 new renders, with all the various versions I created

11-18-2003, 02:28 PM
The first texture is fantastic!!!! :buttrock: :buttrock: :buttrock:

Jabor: I'll be very happy to help you, ask me anything you need.
The car is created using a backdrop from a blueprint from http://www.onnovanbraam.com/
I don't use anything in particular while modeling, just make some tries and a bit of experience using the metanurbs/subdsurfaces.

When the model is complete, I usually launch a render in GI to study the behaviour of light and shadows on the model. You'll need also photos for that.
At least I try to reach the same effect using a distant light for the sun, a spot or area light for the area shadows, and some fill lights to raise the luminosity of the scene; remember to raise down to 0 the ambient light, and also the fill lights must exlude the ground or you'll have too many shadows.
A good trick for keeping the scene smaller and faster is to set how many parts you can in different scenes and composite the image at the end, for example I used this trick for the images where are more cars, cause both my 1700+ and my 2500+ athlons suffered with high subdividions on the cars.
Just remenber to set a ground plane with the alpha channel set to "Shadow Density".
Hope to be useful, bye!

p.s. I love Brasil!

11-18-2003, 05:22 PM
Grats for the model! It's very precise and cool. Removing the white dots really made the pictures a lot better! Did U made the textures or downloaded?
Oh, and one more thing: on the pictures on page1 - what the hell is a car like this doin' on the streets??!! :)
