Bella Render GUI v21.4.0 (x64)

Bella is a spectral render engine which models the complexities of optical physics in ways that are both as correct as possible, and which are yet made intuitive and accessible.
Simplicity is a key focus of Bella. The Bella solvers have no obscure non-physical parameters, such that there is very little to learn, and very little trial and error involved in rendering any particular scene.

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.
