What creative, brand and production objectives drove Sulwhasoo’s CGI advertising direction?
The Sulwhasoo campaign set out with three parallel objectives: craft a visually distinctive luxury narrative, reinforce the Korean heritage of the brand, and meet demanding production schedules without compromising on quality. These goals shaped every stage of the CGI pipeline in Houdini, from concept to final render.
- Creative ambition: Deliver fluid, jewel-like animations that evoke the brand’s signature ginseng and botanical extracts.
- Brand alignment: Integrate traditional Korean motifs—lotus petals, calligraphic strokes—while preserving a modern, minimal aesthetic.
- Production efficiency: Leverage procedural workflows to iterate rapidly on look-development, versioning, and final compositing.
By defining these objectives up front, the team ensured that every node network and render pass directly supported the campaign’s narrative. For example, the emphasis on “petal unfolding” drove the use of Houdini’s finite element method (FEM) solver for realistic soft-body dynamics, rather than relying on simple blend-shape rigs. This approach gave the petals a natural elasticity and micro-detail wrinkles, reinforcing the premium feel.
To echo Sulwhasoo’s minimalist branding, creative directors asked for precise control over light and material. This requirement led TDs to build a modular shading library in Mantra and Arnold, with custom OSL shaders that mimic semi-translucent ginseng cells. Each shader was parameterized in Houdini’s MaterialX framework, allowing for real-time A/B comparisons on the farm.
On the production side, the timeline demanded weekly cut reviews. A procedural asset pipeline—using HDA (Houdini Digital Asset) wrappers for petals, droplets, and typography—enabled rapid swaps of textures, color grades, and motion presets without rebuilding entire networks. Integrating these HDAs into a Shotgun-driven pipeline meant each version automatically carried metadata for render layers, easing compositing in Nuke.
Ultimately, aligning creative, brand, and production objectives ensured every technical decision—whether choosing a FEM solver, building custom OSL code, or structuring HDAs—directly advanced Sulwhasoo’s luxury image and heritage story while keeping the project on schedule and on budget.
How was the Houdini-based pipeline architected to meet studio, agency and brand requirements?
The Houdini-based pipeline for Sulwhasoo’s CGI advertising was designed to unify the studio’s production demands, the agency’s creative explorations and the brand’s rigorous identity guidelines. Strong emphasis on modularity and procedural control ensured that every art direction tweak—color palette, reflection glossiness or shape silhouette—could propagate through the entire project within minutes.
At its core, we adopted a USD-centric workflow via Solaris to manage assets and shots. Custom digital asset libraries (HDAs) were built for packaging product variants—bottles, caps, textures—into reusable hierarchies. Each HDA exposes branded parameters: lacquer color, metallic finish, embossing depth. This parameterization meant the agency could rapidly iterate cosmetics looks without deep node editing.
- Asset Library HDAs: branded shape and material presets
- PDG Scheduler: automated task distribution and requeues
- Render Farm Interface: Karma XPU with templated AOVs
- Review Platform Hooks: ShotGrid integration for feedback
Task orchestration leveraged PDG and TOPs: simulation tasks (liquid fills, capsule dissolves) run alongside lookdev tasks (procedural materials, volumetric mist) on separate nodes. Failures or upstream changes automatically trigger requeues, cutting manual handoffs by 60%. The resulting parallelism met the agency’s tight turn-around for style-frame updates.
Integration with studio tools used Python hooks and Houdini’s HDK: custom shelf tools and callbacks connect ShotGrid APIs for version tracking. Artists launch new tasks directly from the asset library UI, attaching notes and approval flags that sync with agency dashboards. This ensured both the brand team and creative agency saw real-time progress and flagged feedback inside the same system.
For rendering, we standardized on Karma XPU inside Solaris, outputting multi-layer EXRs with tailored AOVs—specular, subsurface, shear dispersion—reflecting Sulwhasoo’s signature radiant glow. Render settings are templated per shot, but parameter overrides allow the agency to adjust light color or camera lens parameters without breaking compliancy with brand tonality.
Final compositing links EXR stacks into Nuke via a scripted Loader node, preserving versioned AOV hierarchies and metadata tags. Creative adjustments—color grades, glow passes—reference camera metadata for consistent motion blur and depth of field across shots, preserving the high-end luxury aesthetic in every frame transition.
By architecting a pipeline that blends procedural power, automated orchestration and integrated review, Sulwhasoo’s CGI campaign achieved studio-level efficiency, agency-driven flexibility and brand-aligned consistency. Iterative approvals moved at agency speed, while procedural controls ensured no pixel compromised the Sulwhasoo luxury identity.
Which procedural modelling, rigging and asset-authoring strategies produced the product and packaging assets?
To achieve the refined curves and sharp edges of Sulwhasoo bottles, the team leveraged procedural modeling with VDB-based Boolean workflows. Starting from basic volumes, VDB operations defined “cut” and “add” surfaces, then converted back to polygon meshes. This ensured non-destructive iterations on silhouette and wall thickness.
Packaging labels and boxes used Houdini Digital Assets (HDAs) driven by PDG for batch variations. Attribute-driven UV layouts and color stops allowed artists to tweak palettes without manual UV rework. Caps and pumps were rigged with thin constraint networks and CHOPs channels to simulate subtle spring-back when rotating.
- VDB Boolean chains for body and cap geometry
- HDAs parameterizing wall thickness, fillet radius, label cutouts
- PDG pipelines to generate multiple packaging variants
- Attribute-driven shading channels for gloss, frost, and metallic finishes
- Constraint and CHOP-based micro-animation rigs for lid interactions
Which simulation techniques (FLIP, Vellum, POPs) and solver strategies delivered the campaign’s elegant motion language?
In Sulwhasoo’s campaign, Houdini’s triad of solvers—FLIP, Vellum, and POPs—was orchestrated to achieve liquid elegance, soft-contact fidelity, and mist-like diffusion. Strategic parameter coupling, substep tuning, and solver transitions ensured each element held a luxurious fluidity without compromising control or render performance.
FLIP setups: velocity control, particle separation, and secondary splash generation
The liquid carrier uses a FLIP tank with a custom velocity volume imported via a VDB. A Volume Warp node refines directional flow, ensuring the serum-like fluid spills with predictable curvature. Global substeps ramp up during high-acceleration frames, limiting particle jitter even in thin pours.
- Resample within the FLIP Object: enforce uniform particle spacing before simulation
- Attribute Wrangle on P: separate clusters by defining proximity thresholds
- Pop Particle Fluid or Flip Source: spawn secondary droplets during surface collisions
After primary simulation, separating fine droplets involves transferring FLIP particles into a second FLIP object set to droplet mode, then using a group SOP to isolate high-velocity particles and applying a lightweight drag force for natural splash decay.
Vellum constraints, pressure-driven inflation and porosity tuning for soft-contact interactions
For soft caps and elastic membranes, a Vellum Cloth solver with pressure constraints simulated bulging and gentle recoil. The initial mesh is pre-processed with a PolyReduce to balance resolution and solver stability. Porosity is tuned via the Vellum Configure Grain node, adjusting internal friction to control how the material drapes over contacting glass surfaces.
Key steps include:
- Define pressure point groups using a connectivity SOP to drive local inflation
- Increase substeps in Vellum Solver to 8 for crisp contact resolution
- Blend between rigid and cloth via stiffness ramps in Vellum Constraints
The result is a soft-contact interaction where the cap cushions against the bottle lip, with micro-creases driven by anisotropic friction and auto-adjusted strain limits, conveying both luxury and mechanical precision.
How were materials, lookdev and lighting authored for photoreal cosmetics and Korean luxury aesthetics in Houdini?
In Houdini, achieving photoreal cosmetics with a Korean luxury feel starts by building a procedural shading network that balances translucency and micro-detail. We used the Principled Shader within Solaris to layer a thin SSS base, a specular coat for dewy reflections, and a fine anisotropic layer to mimic subtle pigment flow. Each parameter remains driven by ramps and masks for rapid iteration.
Lookdev began in a dedicated Solaris stage, where USD-based materials allowed non-destructive overrides. High-resolution UDIM textures defined roughness and normal detail, while a micro-bevel SOP generated curvature maps. This ensured that every contour of the lipstick bullet, compact case, or serum droplet responded to light in a controlled yet organic manner, reinforcing the Korean luxury aesthetic of clarity and refinement.
- Layered SSS and specular coats: balances soft glow with sharp highlights.
- Anisotropic roughness: drives directional shine on metallic caps and applicators.
- Curvature-driven micro-facet normal: enhances edge crispness and volume.
- Procedural masks and ramps: unify color accents and tonal harmony.
Lighting was established using a hybrid HDRI rig and targeted area lights in the LOPs Light Mixer. A soft key light provided overall illumination, while narrow gobos added patterned reflections on metal surfaces. Rim lights with gentle falloff emphasized shapes without harsh cutouts. Throughout, adjustments were made interactively in the Karma viewport to guarantee consistent CGI Advertising render quality aligned with the brand’s polished, premium vision.
What rendering, AOV strategy, compositing workflow and color-management decisions ensured studio-grade final frames?
For Sulwhasoo’s luxury campaign we built a hybrid render pipeline in Houdini using Redshift for fast GPU displacement and Karma for complex volumetrics. We output 16-bit half-float deep EXRs and leveraged a careful AOV strategy to isolate every reflection, subsurface scatter and light group. This approach preserves maximum dynamic range and gives compositors fine control over each component.
- beauty_diffuse: base color without specular bounces
- beauty_specular: raw specular and anisotropy
- sss_scatter: layered skin and wax subsurface
- reflection_env: HDRI and portal contributions
- cryptomatte: per-material mattes for targeted adjustments
- depth & motionvectors: depth-of-field and smooth retiming
In Nuke, we combined AOVs using a controlled composite tree. Our key principle was “build up, don’t bake down”: each pass is brought in linear, aligned to ACEScg, graded with OCIO transforms, then tone-mapped only at the very end. Procedural gizmos handle specular balance, while blurs reference the depth AOV to recreate filmic depth-of-field without re-rendering.
For consistent color across multiple deliverables we standardized on ACES 1.2: scene-referred in Houdini, scene-linear master EXRs, and display-encoded frames via Output Device Transforms (ODTs). This guarantees that the final sRGB, DCI-P3 or Rec.2020 deliverables perfectly match the color intent from look-dev through compositing, ensuring truly studio-grade final frames.
