Editor\u2019s note: This post is part of our weekly <\/i>In the NVIDIA Studio<\/i><\/a> series, which celebrates featured artists, offers creative tips and tricks, and demonstrates how <\/i>NVIDIA Studio<\/i><\/a> technology improves creative workflows. We\u2019re also deep diving on new <\/i>GeForce RTX 40 Series GPU<\/i><\/a> features, technologies and resources, and how they dramatically accelerate content creation.<\/i><\/p>\n

The Portal: Prelude RTX<\/i><\/a> gaming mod \u2014 a remastering of the popular unofficial Portal <\/i>prequel \u2014 comes with full ray tracing<\/a>, DLSS 3<\/a> and RTX IO<\/a> technology for cutting-edge, AI-powered graphics that rejuvenate the legendary mod for gamers, creators, developers and others to experience it anew.<\/p>\n

Nicolas \u201cNykO18\u201d Grevet, a software engineer behind Portal: Prelude<\/i>, collaborated with modder David Driver-Gomm to create the project \u2014 which launched today as a free download on Steam<\/a> \u2014 using NVIDIA RTX Remix<\/a>. The free modding platform enables users to quickly create and share RTX mods for classic games. Learn about the duo\u2019s workflow this week In the NVIDIA Studio<\/i>.<\/p>\n<\/p>\n

Plus, this month, graphics card partners will begin to offer the 16GB version of the GeForce RTX 4060 Ti GPU<\/a>, featuring the state-of-the-art NVIDIA Ada Lovelace architecture that supercharges creative apps and productivity while delivering immersive, AI-accelerated gaming with ray tracing and DLSS 3. The GPUs are well-suited for working in larger 3D scenes, editing videos in up to 12K resolution and running native AI foundation models<\/a>.<\/p>\n

All of this is backed by the July NVIDIA Studio Driver, which supports these latest updates and more, available for download today.<\/p>\n

In addition, the NVIDIA Studio<\/a> #StartToFinish community challenge is in full swing. Use the hashtag to submit a screenshot of a favorite project featuring its beginning and ending stages for a chance to be featured on the @NVIDIAStudio and @NVIDIAOmniverse social channels.<\/p>\n

A Portal Into Creativity<\/b><\/h2>\n

Portal: Prelude<\/i>\u2019s storyline revolves around what\u2019s called the Genetic Lifeform and Disk Operating System, or GlaDOS, an AI created by Aperture Science, the fictional scientific research corporation key to the original game\u2019s plot.<\/p>\n

With extra chapters, test chambers, challenges and an extended storyline, the most popular Portal<\/i> mod of all time was recognized by Mod DB with a \u201cMod of the Year\u201d award. Check out the original game trailer below.<\/p>\n<\/p>\n

\u201cModders have to wear many hats \u2014 they\u2019re simultaneously level designers, 2D artists, scripters, writers, web developers, quality-assurance analysts and so much more,\u201d said Grevet. \u201cThis demands resilience and adaptability.\u201d<\/p>\n

Grevet and Driver-Gomm transformed Portal: Prelude\u2019s<\/i> older, lower-resolution assets into new, high-resolution assets using RTX Remix. Both creators used a GeForce RTX 40 Series GPU, which enabled full ray tracing and DLSS 3.<\/p>\n

The duo first gathered 360-degree screenshots of entire scene levels with RTX Remix.<\/p>\n

Next, they used a component of RTX Remix called RTX Remix Runtime<\/i><\/a> to capture game scenes and replace assets during playback while adding RTX technology to the game, including NVIDIA Reflex<\/a> for low-latency responsiveness.<\/p>\n

\n

\u201cWe could take virtual, in-game 3D screenshots of a level and all of its assets, load the captures in RTX Remix, and literally replace every single asset, texture, geometry and light with up to 100x higher fidelity using open-source 2D and 3D formats.\u201d \u2014 Nicolas \u201cNykO18\u201d Grevet<\/p>\n<\/div>\n

\u201cWe played with AI upscaling a lot,\u201d said Grevet. \u201cIt was tremendously helpful in cutting down on early work and enabled sharper focus on the hero assets that required more hands-on treatment, like characters and non-playable character models, as well as large, predominant textures.\u201d<\/p>\n

These higher-resolution assets in the OpenUSD<\/a> format were uploaded to NVIDIA Omniverse, a platform for connecting and building 3D tools and applications, through the Blender Connector<\/a>. This allowed the team to use their 3D app of choice for modeling new geometry and beveling out edges, all in real time, with full ray-traced fidelity for ultra-photorealistic lighting and shadows. Blender Cycles\u2019 RTX-accelerated OptiX<\/a> ray tracing enabled smooth movement in the viewport.<\/p>\n

\u201cSome assets were practically modeled from scratch, whereas others \u2014 like pipes \u2014 mostly just had their edges beveled out so they were higher poly and smoother,\u201d said Driver-Gomm. \u201cEither way, it was exponentially faster in Omniverse.\u201d All refined assets work from captured meshes rather than by applying new meshes for individual assets, saving an incredible amount of time.<\/p>\n

The team then UV unwrapped the assets, which is the process of opening a mesh to make a 2D texture that can blanket a 3D object for the precise application of textures and materials.<\/p>\n

Grevet and Driver-Gomm then moved to Adobe Substance 3D Painter and Sampler to create high-quality physically based render models. This means images were rendered modeling lights and surfaces with real-world optics. GPU-accelerated filters sped up and simplified material creation, while RTX-accelerated light and ambient occlusion<\/a> baked assets in seconds.<\/p>\n

With all assets in place, the team used RTX Remix to swap older ones with these newer, higher-fidelity models. But the creators weren\u2019t ready to rest on their laurels just yet \u2014 RTX Remix allowed them to relight every single level with realistic, path-traced<\/a> lighting.<\/p>\n

The final result of Portal: Prelude RTX<\/i> is \u201clight-years ahead of what I could do on my own,\u201d said Grevet. \u201cHaving the opportunity to remaster these levels in the way I\u2019d intended for them to look and behave was a nice cherry on top.\u201d<\/p>\n

\u201cThe RTX Remix tool is insanely powerful and almost comes across as magic to me,\u201d said Grevet. \u201cThe ability to capture any part of a game, load it in a 3D tool and chip away at it as if this was being done using the original game\u2019s level editor is insane.\u201d<\/p>\n
