Nuke’s OpenUSD Enhancements Ring in a 3D Renaissance


Editor’s be aware: This put up is a part of Into the Omniverse, a collection targeted on how artists, builders and enterprises can rework their workflows utilizing the newest advances in OpenUSD and NVIDIA Omniverse.

3D designers and creators are embracing Common Scene Description, aka OpenUSD, to remodel their workflows.

Artistic software program firm Foundry’s newest launch of Nuke, a robust compositing instrument for visible results (VFX), is bringing elevated assist for OpenUSD, a framework that gives a unified and extensible ecosystem for describing, composing, simulating and collaborating inside 3D worlds.

With superior compositing and improved interoperability capabilities, artists are showcasing the immense potential of Nuke and OpenUSD for visible storytelling.

Bringing 3D Visions to Life With Nuke and OpenUSD

YouTuber Jacob Zirkle is one such 3D artist.

Impressed by his tenth watch by means of the Star Wars movies, Zirkle wished to create a sci-fi ship of his personal. He first mixed pc graphics parts in Blender and Unreal Engine earlier than utilizing USD to convey the scene into Nuke for compositing.

Zirkle’s ship, constructed utilizing Blender, Nuke, Unreal Engine and USD Composer.

OpenUSD was the glue that held his workflow collectively.

“Normally, I’ve to take care of a number of, various file sorts in my VFX pipeline, and as quickly as one thing will get up to date, it may be an actual ache to use the change throughout the board,” Zirkle mentioned. “However as a result of I used to be utilizing the identical OpenUSD file for all of my packages, I may save the file as soon as, and adjustments get routinely propagated by means of the pipeline — saving me a ton of time.”

Edward McEvenue, an affiliate inventive director at NVIDIA, is utilizing OpenUSD and Nuke to create his quick movie with the working title: “Dare to Dream.”

By the undertaking, McEvenue hopes to visualise elements of automated manufacturing. He makes use of Autodesk 3ds Max and SideFX Houdini for 3D scene creation, Chaos V-Ray for rendering arbitrary output variables and prolonged dynamic vary sequences, and Nuke for compositing parts for remaining renders.

OpenUSD helps streamline knowledge switch between functions, dashing the iteration course of. “Nuke’s USD capabilities permit me to seamlessly transition 3D property between digital content-creation apps, offering a robust instrument for attaining superior compositing methods,” he mentioned.

Different NVIDIA creatives have built-in OpenUSD and Nuke into their 3D workflows. A group of 10 artists developed a absolutely OpenUSD-based pipeline and customized tooling on NVIDIA Omniverse — a growth platform for constructing OpenUSD-based instruments and functions — to convey to life the “Da Vinci Workshop,” a undertaking to encourage better OpenUSD use amongst pipeline builders.

The artists additionally used Adobe Substance Painter, Autodesk 3ds Max, Autodesk Maya, DaVinci Resolve, SideFX Houdini, Pixelogic Zbrush and Omniverse USD Composer. OpenUSD served because the spine of the group’s inside pipeline, providing the flexibleness wanted to collaborate throughout functions with ease.

The “Da Vinci Workshop” OpenUSD dataset is now obtainable on the Omniverse launcher — free for builders and artists.

Foundry Nuke representatives, Omniverse group members and the NVIDIA inventive group just lately joined a livestream to debate their 3D workflows and the influence of OpenUSD. Be taught extra by watching the replay:

Powering Digital Workflows With OpenUSD

The 15.0 and 14.1 updates to Nuke convey important workflow enhancements to these working with OpenUSD.

The up to date GeoMerge node now affords 4 new modes: Merge Layers, Duplicate Prims, Flatten Layers and Flatten to Single Layer. These give customers better management over geometry and OpenUSD layers, permitting for fast merging of advanced buildings, the duplication of workflows and simpler layer administration.

The OpenUSD-based 3D system launched in Nuke 14.0 permits customers to deal with massive, intricate scenes with better ease. And the brand new Scene Graph Popup characteristic in Nuke 15.0 permits customers to simply filter by means of 3D scene knowledge, decreasing time and vitality wanted to spend looking for particular property.

As well as, the primary 3D scene graph now features a search and filter characteristic, simplifying workspace navigation.

Foundry can also be embracing OpenUSD throughout its different merchandise, together with the newest updates to Katana 7.0, which enhance pipeline effectivity by integrating USD-native workflows already aligned with Nuke’s 3D system structure.

Get Plugged In to the World of OpenUSD 

NVIDIA and Foundry are each members of the Alliance for OpenUSD (AOUSD), a company devoted to an open-source future utilizing the highly effective framework. To study extra, discover the AOUSD discussion board and take a look at these assets on OpenUSD.
