From a development team that pioneered commercial physically-based unbiased rendering over two decades ago, Bella represents the next generation in fast spectral rendering.site français
Unlike renderers that employ confusing arbitrary parameters, Bella aims to speak a more natural language, based on real world concepts and units. This means that in addition to rendering quickly, Bella is also very predictable, allowing you to avoid wasting time with trial and error during scene setup.
Fast Spectral Rendering
Bella's state of the art spectral solvers open a world of visual richness and detail that you have been missing with your RGB renderer.
Optical effects such as the beautiful dispersion seen here, emerge naturally with no need of hacks or workarounds.

Focus on Performance
Bella's fast CPU solvers can provide performance several times greater than that of even some non-spectral competitors.
Here, we see Saturn CPU producing results similar to Cycles CPU in Rhino, but in around 1/5 the time.
The difference can be even greater on MacOS, for renderers that do not yet run natively on Apple Silicon.
Time: 6 minutes
Time: 17 minutes
Time: 34 minutes
Bella's painstaking attention to detail in the models and algorithms we use, results in images with simply better light, and more life.
This is something that cannot be added later on in a project, it must be taken as a fundamental imperative from the very beginning.

Bella's fast Saturn solver is especially suitable for architectural work.
For instance, it handles typical sunlit glass facades with ease, using standard glass materials, with no special setup.

Bella's Saturn solver makes quick work of product viz scenes.
The Bella Uber material makes it fun and easy to experiment, as you create appealing and unique looks.

Though host applications may not yet support Apple Silicon, Bella already supports it natively.
Built as Universal Binaries, Bella applications & plugins provide the best possible performance no matter your type of machine.
Bella for Rhino
Bella for Rhino provides a seamless workflow within Rhino 6 & 7.
You will find cameras, materials, and environments where you expect them to be, working how you expect them to work.
Try it today!
Bella for Maya
Bella's nodal system is quite similar to Maya's, so Bella's nodes are a natural fit to be exposed natively in Maya.
Whether you use Maya 2018, 2019, 2020, or 2022, you can give Bella a try today!
Licensing & Support
Bella's deliberately simple floating permanent license ensures you do not lose valuable time to complicated, error-prone license managers.
Core developers strive to be open and responsive, available to assist quickly & directly with any issue you may encounter.

Bella has been created to be the type of software that we, ourselves, prefer to use, not only in how the software itself is designed, but also in how it is offered as a product, and in how it is licensed.
We believe in offering a clear and simple product -- therefore, the only Bella offerings are the seat license, which includes all Bella software and plugins, and the node license (reduced cost, for CLI rendering only), neither of which is locked to any particular machine or operating system.
We do not believe in forcing our honest customers to pay the price (in terms of the inconvenience, and inevitable failure of draconian licensing schemes) to protect Bella from unauthorized use -- therefore, the Bella license is implemented as a simple text file.
We believe strongly in respecting your right to privacy -- therefore, Bella neither requires contacting any remote server to validate or register a license, nor does the software attempt to establish any remote connections, at all, during use.
Bella is developed by Diffuse Logic, a Barcelona-based software company with decades of cumulative experience in the fields of physical simulation and rendering, as well as user-interface design and plugin integration.
