@sciencegirl Wouldn't it be a bit more precise to replace colour by wavelengths? What we perceive is a rainbow of colours, but the colours we actually make up in our brains.

White light looks plain, but it’s actually made of many colours. When light passes through a prism, it slows down and bends, and each colour bends by a different amount. This spreads the colours out into a rainbow

Final update of 2025 for KeenTools is here! What’s new in 2025.3: – FaceBuilder x Character Creator 5 integration – GeoTracker for AE: export to .abc – Support for Blender 5.0, AE 25.6, Nuke 16.1 & 17.0 Betas Download: link.keentools.io/2025-3-tw

The new OpenColorIO Configuration(s) for ACES 2.0 have been released! The `cg-config-v4.0.0_aces-v2.0_ocio-v2.5.ocio` and `studio-config-v4.0.0_aces-v2.0_ocio-v2.5.ocio` configs are already shipped in the OpenColorIO v2.5.0 release. github.com/AcademySoftwar…

@mrchrissea @gleb_alexandrov but the view transform for which display? Can you explain what hybrid support means? blender expected in the past that the working colorspace is linear-bt.709. where do you switch between acescg and lin. bt.709 in the app? and where are all the view transforms of aces 2.0?

@toodee @gleb_alexandrov It's only using the ACES 2.0 view transform, not the entire ACES color pipeline. So this is hybrid support for ACES.

Blender 5.0 will support ACES 2.0. 😋

@gleb_alexandrov you mean by default? Blender 4.5 supports already the OCIO configs for ACES 2.0?!

Physically Based Neural Bidirectional Reflectance Distribution Function Chenliang Zhou, Alejandro Sztrajman, Gilles Rainer, Fangcheng Zhong, Fazilet Gokbudak, Zhilin Guo, Weihao Xia, Rafal Mantiuk, Cengiz Oztireli arxiv.org/abs/2411.02347 Abstract: We introduce the physically based neural bidirectional reflectance distribution function (PBNBRDF), a novel, continuous representation for material appearance based on neural fields. Our model accurately reconstructs real-world materials while uniquely enforcing physical properties for realistic BRDFs, specifically Helmholtz reciprocity via reparametrization and energy passivity via efficient analytical integration. We conduct a systematic analysis demonstrating the benefits of adhering to these physical laws on the visual quality of reconstructed materials. Additionally, we enhance the color accuracy of neural BRDFs by introducing chromaticity enforcement supervising the norms of RGB channels. Through both qualitative and quantitative experiments on multiple databases of measured real-world BRDFs, we show that adhering to these physical constraints enables neural fields to more faithfully and stably represent the original data and achieve higher rendering quality. #neural #rendering #brdf
