About Romain

3D Artist | WebGL | Houdini FX | Realtime | AI | Technical Consultant


Do you have an ambitious visual project but lack the time (or team) to bring it to life? I'll take care of it.

From product packshots to 3D films, from advertising to gaming: I transform your briefs into memorable visuals — photorealistic renders, VFX, simulations, motion design, WebGL applications. You maintain creative control, I manage the technical execution.

Why me over someone else?

I master the entire 3D pipeline: modeling, texturing, lighting, animation, rendering, editing, color grading. Blender, Cinema 4D, Unreal, Unity, After Effects; I choose the tool best suited for your project.
I also code interactive WebGL applications (Three.js, PlayCanvas, JavaScript).

And when it comes to pushing further (complex simulations, procedural generation, advanced VFX), I have Houdini and VEX expertise that few freelancers offer. A single point of contact from brief to delivery.

Generative AI: an accelerator, not a shortcut

I use ComfyUI and advanced workflows to quickly explore creative directions or produce otherwise impossible visuals. Every deliverable passes through my art direction — never raw machine content.

Consultant & Prototyping

Need a technical opinion before launching a project? I advise on your choices (3D, VR, AI, pipelines) and prototype your concepts to validate feasibility.

They trusted me

Adidas, Puma, Roland-Garros, Swarovski, Nescafé, Saint-Gobain, Japanese gaming studios + NDA projects.

**Sectors**: Advertising, luxury, industry, events, medical, architecture, gaming, risk prevention.
