Discover how Wren Kitchens is reinventing in-store kitchen design with real-time 3D, VR, and path-traced rendering. Katie Fisher, Head of the 3D team at Wren Kitchens, shares how a small group of developers and artists evolved into a 33-strong department powering intuitive planning tools, immersive showroom experiences, and photoreal “Wrenders” at scale.
See how Wren uses Unity to connect planning, visualization, and rendering into a single pipeline that delights customers, boosts designer productivity, and dramatically reduces operational costs.
Watch the full video to learn how:
- Planner 2D, Planner 3D, and Plan VR work together, linking CAD-driven business logic with a Unity-powered 3D/VR view so customers can explore their future kitchen in real time.
- Even non-CAD experts can turn an empty floor plan into a fully planned, VR-ready kitchen in under four minutes using automated layout suggestions, business rules, and prop auto-population.
- Wren’s switch from a complex V-Ray/Blender + EC2 cloud rendering stack to Unity’s built-in path tracer cut average render times from ~10 minutes to ~30 seconds and slashed cloud costs from ~£25,000 per month to nearly zero.
- Simplifying the pipeline, from three-hour build times and 100GB material uploads down to three-minute builds, has boosted artist productivity, reduced duplicated material work, and made iteration far easier.
- Designers now generate higher-fidelity Wrenders at 2K and beyond, experiment with time-of-day lighting, HDRIs, and photography-style controls, and use automated camera angles to deliver full suites of hero and detail shots for every customer.
