Houdini Simulations & Bottle Craft: Elevating Luxury Perfumery

I. The Trap of STEP Files on Blown Glass: Interior Bottom Thickness

In luxury perfumery, a common misconception is assuming that importing the CAD / STEP file supplied by the glassmaker is enough to produce a realistic packshot or film. However, when glass is blown — as on the iconic bottles of Maison Francis Kurkdjian (Baccarat Rouge 540) — the internal thickness of the glass (the bottom base and inner walls of the flacon) is non-uniform and impossible to predict in a STEP file.

STEP files are only useful for external proportions. To capture true refraction, the visual weight of the glass base, and authentic crystal brilliance, every internal thickness and every light-catching edge must be reworked by hand and verified by eye. Our teams have mastered this specific craft over more than 10 years working on these products.

“A STEP file only gives the outer geometric shell. The soul of a 3D bottle is born when the artist hand-sculpts the non-uniform thickness of the glass base and the subtle imperfections that make light vibrate.”

II. “Perfectly Imperfect” Geometry, Bokeh & Multi-Line Campaigns

Depending on the scale and timeline of the campaign, our Digital Atelier adapts its approach:

1. Large-Scale 360° Productions (Prints & Films): for Maison Francis Kurkdjian's Lunar New Year (Year of the Snake) campaign carried out over 2 months in collaboration with Wizz, locking a robust master scene in Maya, ZBrush, Substance Painter, Houdini, Redshift, and Nuke enabled us to deliver 20 high-definition prints and 5 videos (1 greeting card and 4 hero product films).
2. Multi-Line Holiday Frescoes & Haute Couture: on the Viktor & Rolf Holiday films (Starry Ball, Enchanted Holidays, Flowerbomb Christmas), our teams handled the 3D environments (snowy Amsterdam streets and canals), Houdini tulle gown simulations, and lookdev across a multitude of bottles (Flowerbomb, Spicebomb, Bonbon, snowflake gift sets).
3. Minimalist Light Sprint (3ds Max & V-Ray): conversely, on Hugo Boss — The Scent (delivered in 10 to 15 days), we placed the bare bottle on a warm studio cyc and let light do all the work through “perfectly imperfect” geometry, a polished cap, strong optical defocus (bokeh), and manual animation of lights, camera, and product.

III. Physical Houdini Simulations (FLIP, Vellum & FX)

Through our procedural Houdini pipeline paired with Redshift Render, V-Ray, and Nuke, our FX artists control every detail — from the motion of a braided gold ribbon to Haute Couture tulle simulations and refractive caustics — giving the art director frame-by-frame control right up to final delivery.
