Maxwell has two spectral modes of varying accuracy. The more complex method is often used for optics. https://maxwellrender.com/ https://maxwellrender.com/
Manuka by Wētā FX is spectral and has been used in several feature films https://dl.acm.org/doi/10.1145/3182161 https://dl.acm.org/doi/10.1145/3182161 and https://www.wetafx.co.nz/research-and-tech/technology/manuka https://www.wetafx.co.nz/research-and-tech/technology/manuka
- alkonaut 3y agoIf you want to look under the hood and find the big production ones like too complex, I can recommend peeking at this one. It's a great example example of just the minimum of a spectral path tracer https://github.com/TomCrypto/Lambda https://github.com/TomCrypto/Lambda
- pixelpoet 3y agoThere's also Indigo Renderer and the open source LuxRender: https://indigorenderer.com https://indigorenderer.com https://luxcorerender.org https://luxcorerender.org
- dagmx 3y agoNote that Lux isn’t spectral anymore. The older version is though.
- pixelpoet 3y agoFunny, I added the original implementation of spectral rendering to Lux and then they took it out :D
- nextaccountic 3y agoWhy did they remove it?
- pixelpoet 3y agoI have no idea (it wasn't exactly the same project, LuxCore vs Lux), and PBRT, on which Lux was based, later moved to full spectral rendering. I guess they feel they'd rather reduce register pressure a bit than support it.
