This Week ‘Within the NVIDIA Studio’ ‘Portal: Prelude RTX’ Rejuvenates Legendary Gaming Mod

Editor’s be aware: This publish is a part of our weekly Within the NVIDIA Studio collection, which celebrates featured artists, affords inventive suggestions and tips, and demonstrates how NVIDIA Studio expertise improves inventive workflows. We’re additionally deep diving on new GeForce RTX 40 Sequence GPU options, applied sciences and sources, and the way they dramatically speed up content material creation.

The Portal: Prelude RTX gaming mod — a remastering of the favored unofficial Portal prequel — comes with full ray tracing, DLSS 3 and RTX IO expertise for cutting-edge, AI-powered graphics that rejuvenate the legendary mod for players, creators, builders and others to expertise it anew.

Nicolas “NykO18” Grevet, a software program engineer behind Portal: Prelude, collaborated with modder David “Kralich” Driver-Gomm to create the venture — which launched immediately as a free obtain on Steam — utilizing NVIDIA RTX Remix. The free modding platform permits customers to shortly create and share RTX mods for traditional video games. Study concerning the duo’s workflow this week Within the NVIDIA Studio.

Plus, this month, graphics card companions will start to supply the 16GB model of the GeForce RTX 4060 Ti GPU, that includes the state-of-the-art NVIDIA Ada Lovelace structure that supercharges inventive apps and productiveness whereas delivering immersive, AI-accelerated gaming with ray tracing and DLSS 3. The GPUs are well-suited for working in bigger 3D scenes, modifying movies in as much as 12K decision and working native AI basis fashions.

All of that is backed by the July NVIDIA Studio Driver, which helps these newest updates and extra, obtainable for obtain immediately.

As well as, the NVIDIA Studio #StartToFinish neighborhood problem is in full swing. Use the hashtag to submit a screenshot of a favourite venture that includes its starting and ending levels for an opportunity to be featured on the @NVIDIAStudio and @NVIDIAOmniverse social channels.

A Portal Into Creativity

Portal: Prelude’s storyline revolves round what’s referred to as the Genetic Lifeform and Disk Working System, or GlaDOS, an AI created by Aperture Science, the fictional scientific analysis company key to the unique sport’s plot.

With additional chapters, check chambers, challenges and an prolonged storyline, the most well-liked Portal mod of all time was acknowledged by Mod DB with a “Mod of the 12 months” award. Try the unique sport trailer under.

“Modders need to put on many hats — they’re concurrently degree designers, 2D artists, scripters, writers, net builders, quality-assurance analysts and a lot extra,” stated Grevet. “This calls for resilience and flexibility.”

Grevet and Driver-Gomm reworked Portal: Prelude’s older, lower-resolution belongings into new, high-resolution belongings utilizing RTX Remix. Each creators used a GeForce RTX 40 Sequence GPU, which enabled full ray tracing and DLSS 3.

The duo first gathered 360-degree screenshots of complete scene ranges with RTX Remix.

Subsequent, they used a element of RTX Remix referred to as RTX Remix Runtime to seize sport scenes and change belongings throughout playback whereas including RTX expertise to the sport, together with NVIDIA Reflex for low-latency responsiveness.

“We might take digital, in-game 3D screenshots of a degree and all of its belongings, load the captures in RTX Remix, and actually change each single asset, texture, geometry and light-weight with as much as 100x increased constancy utilizing open-source 2D and 3D codecs.” — Nicolas “NykO18” Grevet

“We performed with AI upscaling loads,” stated Grevet. “It was tremendously useful in slicing down on early work and enabled sharper deal with the hero belongings that required extra hands-on therapy, like characters and non-playable character fashions, in addition to massive, predominant textures.”

These higher-resolution belongings within the OpenUSD format had been introduced into NVIDIA Omniverse, a platform for connecting and constructing 3D instruments and purposes, by way of the Blender Connector. This allowed the crew to make use of their 3D app of alternative for modeling new geometry and beveling out edges, all in actual time, with full ray-traced constancy for ultra-photorealistic lighting and shadows.

“Some belongings had been virtually modeled from scratch, whereas others — like pipes — principally simply had their edges beveled out in order that they had been increased poly and smoother,” stated Driver-Gomm.

The crew then UV unwrapped the belongings, which is the method of opening a mesh to make a 2D texture that may blanket a 3D object for the exact utility of textures and supplies.

Grevet and Driver-Gomm then moved to Adobe Substance 3D Painter and Sampler to create high-quality bodily primarily based render fashions. This implies photographs had been rendered modeling lights and surfaces with real-world optics. GPU-accelerated filters sped up and simplified materials creation, whereas RTX-accelerated mild and ambient occlusion baked belongings in seconds.

With all belongings in place, the crew used RTX Remix to swap older ones with these newer, higher-fidelity fashions. However the creators weren’t able to relaxation on their laurels simply but — RTX Remix allowed them to relight each single degree with practical, path-traced lighting.

“The RTX Remix software is insanely highly effective and nearly comes throughout as magic to me,” stated Grevet. “The flexibility to seize any a part of a sport, load it in a 3D software and chip away at it as if this was being finished utilizing the unique sport’s degree editor is insane.”
