The GT3 RS; Untamed.

The idea

Most of what makes a GT3 RS fast is invisible. At speed, the air presses the car into the road, and you never see it happen. The wing, the splitter, and the diffuser are all shaped by something you can’t look at.

The piece's early stage LookDev

This piece is about making that force visible, and about the feeling that comes with it.

A GT3 RS is a race car with a license plate. Driven wrong, it can kill you, and it demands your full attention every time you touch it.

Some machines aren’t driven; They’re negotiated with.

Porsche Final LookDev
The setting is a sterile wind tunnel. Nothing is warm or inviting about this, only the cold light of a place where dangerous things are studied. The sterility is the point, because a car this loud looks more threatening in a room this quiet.

The feel.

I went retro and grainy, dramatic and a little horror-adjacent. Nothing here is meant to flatter the car. The shape does the work, because that silhouette is one of the most recognizable on earth, and in near darkness you still know exactly what you’re looking at.

Porsche Wind Wrap
Every frame is built around the wind simulation wrapping the body, curling off the wing, and tearing into chaos behind it.

The cuts between views feel like security footage with no operator, as if someone is watching from far away and keeping their distance.

The camera barely moves because the car isn’t the thing in motion.

The air is.

The final Houdini wind simulation

At the end, the car cuts to the track, coming up on turn 2.

It has been held still the whole time, and it was never tamed.

Porsche on track
The straight into Eau Rouge.
Spa

Spa Francorchamps, Ardennes, Belgium.

The track is Spa-Francorchamps, a legendary circuit set in the forests of Belgium and home to some of the biggest GT3 races in the world.

It was a deliberate choice, and not only for its status. It was chosen for its second turn, Eau Rouge.

Eau Rouge is a steep downhill plunge into a compression, followed by an uphill climb, all taken at enormous speed.

Eau Rouge is arguably more iconic than the circuit itself.

It’s also one of the most aero-heavy, downforce-demanding corners in racing, which makes it exactly the challenge the GT3 RS was built to excel at.

And it did.

Nerd Alert!

Everything below follows the order the work happened, not the order the piece plays.

Under the hood.

  1. 01

    In Houdini

    The setup: the car as a VDB collider, wind stemming from a grid of 12 spheres, then the solver is driven by a wind force along the y-axis. It's a simple, basic setup, but it does the job!

    Cost scales brutally with resolution: both the resolution of the collider VDB and the voxel size of the sim. So the real work was deciding where detail mattered and where it didn’t.

  2. 02

    Back to Blender,

    The laser was the hardest part. Real wind tunnels use sheets of light to slice through smoke and reveal the vortices, and that’s the look I was chasing. But the physics produces violent, spiraling chaos, while the look I wanted was a clean, graphic cutout. A perfect laser fought the simulation.

    So I made it imperfect, letting it bend and branch so the chaos blends in as the light catches the smoke around it. It reads as a clean shape while the air stays honest. Balancing simulation quality against compute time was the other half of the fight.

  3. Loading model

    03

    The circuit outline is widely available everywhere on the internet.

    The challenge was modeling everything around it.
