Bella Render v20.15.0 For Rhino 6 / SketchUp 2017+ / Maya 2018-2019

Bella is a spectral, physically-based renderer, designed from a clean sheet to produce the most beautiful images yet seen. With a flexible nodal scene description, intuitive yet powerful material model, and real-world camera model, Bella seeks to help virtual photographers unlock their true potential

Though the rendering process involves complex mathematics, Bella strives always to expose control over the process in natural and logical ways, so as to achieve predictability, and thus increased productivity, in everyday use.

Diffuse Logic is pleased to invite all who wish to participate, to take Bella for a test-drive, in an open pre-release beta. For those who submit images accepted to the Bella gallery, license discounts will be offered.

Bella is a state of the art spectral renderer, built from the ground up to achieve unmatched realism.

By adhering to a physics-based approach, it not only produces truly photographic images, but does so with a predictability that both simplifies use, and enhances productivity.

Through its flexible node system, and its intuitive physically-based material and camera models, Bella seeks to help you unlock your true potential as a digital artist & photographer.

Features

Spectral Rendering
Bella works in spectral space, allowing effects such as BSDF wavelength dependency, diffraction, or atmosphere to be modeled far more accurately than in color space.

Complex Caustics
Bella's Apollo solver is capable of solving caustics through specular surfaces, for accurate rendering of swimming-pool caustics, caustics seen through windows, emitters enclosed in glass, etc.

Customer-first Licensing
Bella's licensing is uncommonly and deliberately customer-centric. Both licenses (seat and node) are floating, permanent, and designed to be trouble-free.

Layered Materials
Bella's materials provide real layers with inner subsurface scattering. Light interacts physically with the substrate, the layer, and thin films, in a very efficient way

Thin Film
The Thin Film node, which may be applied to a material layer or substrate, simulates a nanometer-scale film, providing physically-accurate iridescence.

Nested Dielectrics
The nested priority feature in Bella materials allows correct and convenient rendering of intersecting dielectric (i.e. glass, liquid) volumes.

Complex IOR
The Complex Material provides a simple way of using measured spectral refractive index data. Use of external IOR files or data is optional.

Smart Materials
Bella's Smart Materials provide a quick and easy way to create and use metals, ceramics, and plastics, through just a few simple parameters.

Textures
Like everything else, textures in Bella are node-based, allowing an output from one texture to be used as an input to another.

Pervasive Instancing
Bella provides extensive support for instancing -- indeed, everything that can be seen in a Bella scene is inherently an instance.

Physical Sky & Sun
Bella's physical sun and sky model may be controlled by date/time and location, or by specifying direction explicitly.

Procedural Lights
Bella provides several types of built-in procedural lights, including point, spot, area, and directional

Thin & Thick Lens
In addition to its standard thin lens, Bella also provides a unique thick lens, which simulates complex effects like chromatic aberration.

Sensor Bloom
The Bella camera supports simulation of sensor bloom: when a pixel is saturated beyond its capacity, it bleeds energy into adjacent pixels.
