Behind the Scenes: Koenigsegg One

Behind the Scenes: Koenigsegg One

My name is Abhinav Gajmoti. I am a B.Com (Hons.) graduate from New Delhi, India. I started learning Blender around two years ago by watching YouTube tutorials and Google. I have no art school experience or any art background.


The shape of the car inspired me to take on a bigger challenge as a learner because I personally think you gain more skills by taking on complex shapes and objects, rather than simple objects. This car seemed perfect for my skill level, as it has an interesting shape and something I never did before: car texturing.

Tools I Used

I used Blender 2.79 for modeling and 2.8 for rendering, GIMP, Inkscape, and Photoshop for this project. I mainly use Inkscape to create dashboard icons and all, as it gives me more control on the shapes and is much easier to work with for resizing.


I got the blueprints from and the blueprint was a perfect match, almost, as it was created from a 3D Model. I also gathered many reference images from a video by on YouTube (too bad I stumbled upon it quite late and had to make many changes after that). The official website has some really good reference images.


This is the first time I fully applied the shrinkwrap modeling technique. Shrinkwrap technique takes a bit of time and a small toll on the render time, but it is worth it and makes your workflow faster. It was tricky around some parts of the car, especially around the vents.

I begin modeling, generally, starting with the wheels and calipers. Whenever I had trouble modeling a part, I jumped to a different part of the car. For the curved part of the door, I simply made another guide mesh for the curved part.

The inside of the Koenigsegg is so complex that I only modeled the exhaust pipe to fill in the empty space behind the grill.

Sometimes, even the simplest of shapes can be hard to model, like the active rear wing. Seems simple, right? Well, not so much, I personally found it one of the hardest parts of the car, if you are going for accuracy.

Modeling the Interior

I find modeling the interior of a car to be a challenge. While it may not be accurate or properly aligned, it was pure fun modeling the interior. I didn’t use any blueprint for the interior or any CAD drawings. All of the interior work was done by eyeballing and taking hints from reference images. It’s not accurate, but it gets the job done.


For this project, I used the cut-out technique I learned from YouTube. Basically, you create a high poly shape of the texture part. You duplicate the original part (UV unwrap first) and then use Boolean with the intersect method and you texture paint it and then use the texture image for the original model.

I made the mistake of texturing the car before finalizing it, and it turned out to be a huge pain. For instance, I forgot to make the fuel cap before texturing and after making it, the texture was distorted because of the change in the UV. I then had to repeat the whole process of texturing.

Some texture areas were simple and were merely done by adding a different material to the part. Other textures were created in Inkscape, like the control panel:

The hardest texture to create was carbon fiber. Because carbon fiber is more than a zig-zag pattern, I couldn’t do it procedurally. So, I used the texture from Here’s how a carbon fiber texture looks:


I generally use HDRi only for lighting. I don’t add any other light source other than HDRi to light the scene, even for the studio renders where I used a different HDRi. HDRis, most of them, give enough light information to light an outdoor scene. However, it might not be the best method in all cases.

Setting up the scene

I read online that to make good renders, pick the car and backplate you like and make them match. I used the Versveldpas HDRi from HDRihaven and the backplate from the same. I used Photoshop for directional blur to make the scene more realistic and also for the fact that GIMP cannot do path blur as of now. I did quite some testing with different backplates and HDRIs, but I ended up settling with the one I liked in the beginning.

Because I am only modeling the car, I needed something to catch the shadows of the car. WIthout the shadows, the scene would not look real at all. This is quite easy to do. Add a plane and check the shadow catcher option. As the name suggests, it “catches” shadows of objects placed in the scene and only renders the shadows it catches. I also UV unwrapped the plane with the backplate as image texture to give more realistic reflections. For this, I used the Project from View method with the UV covering the ground beneath the car.

For the wheel rotation, I find the motion blur in Blender very fast and easy to work with. I applied the usual method of adding blur:

The Blender community was quite helpful in critiquing and improving the scene, and I really appreciate their help.


I used a very basic composition with glare and some color adjustments.
