What is Neural Rendering?
https://www.zumolabs.ai/post/what-is-neural-rendering
“The key concept behind neural rendering approaches is that they are differentiable. A differentiable function is one whose derivative exists at each point in the domain. This is important because machine learning is basically the chain rule with extra steps: a differentiable rendering function can be learned with data, one gradient descent step at a time. Learning a rendering function statistically through data is fundamentally different from the classic rendering methods we described above, which calculate and extrapolate from the known laws of physics.”

Foundry Nuke Cattery – A library of open source machine learning models
The Cattery is a library of free third-party machine learning models converted to .cat files to run natively in Nuke, designed to bridge the gap between academia and production, providing all communities access to different ML models that all run in Nuke. Users will have access to state-of-the-art models addressing segmentation, depth estimation, optical flow, upscaling, denoising, and style transfer, with plans to expand the models hosted in the future.

Scene Referred vs Display Referred color workflows
Display Referred it is tied to the target hardware, as such it bakes color requirements into every type of media output request.
Scene Referred uses a common unified wide gamut and targeting audience through CDL and DI libraries instead.
So that color information stays untouched and only “transformed” as/when needed.

Autodesk open sources Aurora – an interactive path tracing renderer that leverages graphics processing unit (GPU) hardware ray tracing
https://github.com/autodesk/Aurora
Goals for Aurora
- Renders noise-free in 50 milliseconds or less per frame.
- Intended for design iteration (viewport, performance) rather than final frames (production, quality), which are produced from a renderer like Autodesk Arnold.
- OS-independent: Runs on Windows, Linux, MacOS.
- Vendor-independent: Runs on GPUs from AMD, Apple, Intel, NVIDIA.
Features
- Path tracing and the global effects that come with it: soft shadows, reflections, refractions, bounced light, and others.
- Autodesk Standard Surface materials defined with MaterialX documents.
- Arbitrary blended layers of materials, which can be used to implement decals.
- Environment lighting with a wrap-around lat-long image.
- Triangle geometry with object instancing.
- Real-time denoising
- Interactive performance for complex scenes.
- A USD Hydra render delegate called HdAurora.

Virtual Production Offers Real Savings For Studios Of All Sizes
Rob Legato, the award-winning FFX Supervisor whose work you may have seen in movies like Titanic, Avatar and The Jungle Book, is incredibly bullish on virtual production. At the Microsoft Production Summit, presented by NVIDIA NVDA +0.2%& Unreal Engine in Los Angeles, he reported that he recently did a movie with Ben Affleck and Matt Damon in twenty-four days, “Cutting down the days cut down the budget, and it’s amazing what a difference that can make. Productions can now do for $25 million what used to cost $100 million.”
