Bella Render - Commercial Licence

Bella Render is a high-end spectral render engine for designers and architects who require uncompromising physical accuracy. Unlike traditional RGB-based renderers, Bella simulates light as a continuous spectrum — capturing diffraction, dispersion, and thin-film interference — to produce hyper-realistic results that standard renderers simply cannot match.

Integrating seamlessly with Rhino 3D via a dedicated plugin, Bella provides real-time interactive rendering and effortless scene setup. Its proprietary Apollo solver delivers clean, noise-free images faster than many traditional unbiased engines — making it the definitive choice for jewellery designers, product engineers, and architectural visualisers.

Key Features

• Spectral Solver — Simulates light as a continuous spectrum rather than RGB, producing superior colour accuracy and realistic optical phenomena including caustics and rainbows.
• Apollo Solver — Proprietary algorithm that handles complex lighting scenarios — such as light through glass — more efficiently than standard path-tracers.
• Real-time Interaction — Integrated interactive preview within Rhino for immediate feedback as you adjust materials or lighting.
• Complex Material System — Physically-based material library supporting layered coatings, subsurface scattering, and anisotropic metals.
• Thin-Film Interference — Reproduces pearlescent and oil-slick surface effects without complex manual shader work.
• Aperture & Lens Effects — Accurate simulation of physical camera hardware including real-world bokeh, bloom, and sensor noise.
• Intel & Apple Silicon Optimised — High-performance rendering on Windows (Intel/AMD) and Mac (native Apple Silicon M1/M2/M3).

Use Cases

• Jewellery Designers — Capturing the precise fire and brilliance of gemstones and the subtle reflections of polished precious metals.
• Product Designers — Creating high-fidelity marketing assets for consumer electronics where material texture and light interaction are critical.
• Automotive Visualisers — Simulating complex metallic flake paints and glass transparency for vehicle interiors and exteriors.
• Architectural Illustrators — Producing atmospheric interior renders with complex natural lighting and accurate material finishes.
• Optics & Engineering — Visualising how light interacts with lenses and prismatic surfaces for technical verification and presentation.

Compatibility

• Rhino Version — Requires Rhino 7 or Rhino 8
• Windows — Windows 11 or 10
• Mac — macOS 12.4 or later; native Apple Silicon (M1/M2/M3) and Intel support
• Plugin Dependencies — Direct Rhino plugin; includes standalone Bella GUI for independent scene management

System Requirements

• Minimum — Modern 64-bit CPU (Intel, AMD, or Apple Silicon); 8 GB RAM; 500 MB disk space
• Recommended — 16 GB+ RAM; high-core count CPU (rendering is CPU-centric but highly optimised); high-resolution monitor for detailed material editing

FAQs

• Is Bella a CPU or GPU renderer? Primarily CPU-based. Highly optimised to use every available thread, making it exceptionally stable and capable of handling very large scenes that might exceed GPU memory.
• Does it work on Rhino for Mac? Yes. Fully compatible with macOS and runs natively on Apple Silicon for peak performance.
• Can I keep working in Rhino while it renders? Yes. Render in the background or use the standalone Bella GUI to free up Rhino for further modelling.
• What makes spectral rendering better? Regular renderers use RGB light. Spectral rendering uses the full wavelength of light — necessary to correctly calculate how light splits through a prism or reflects off complex coatings.
• Is there a trial version? Yes. Bella offers a demo mode — fully functional but adds a watermark and resolution limit until a licence is applied.
