NVIDIA RTX Remix Creator Toolkit Open Source Available Now

NVIDIA RTX Remix empowers modders to remaster classic DirectX 8 and DirectX 9 games with full ray tracing, DLSS 3.5, highly detailed assets, and physically accurate materials. Built on NVIDIA Omniverse, RTX Remix consists of a runtime renderer and a toolkit app that facilitates the modding of game assets and materials.

Last year, NVIDIA open sourced the RTX Remix Runtime, allowing modders to expand game compatibility and advance rendering capabilities. Now, NVIDIA is open sourcing the RTX Remix Toolkit, allowing modders to streamline how assets are replaced and scenes are relit, increase supported file formats for RTX Remix’s asset ingestor, and bolster RTX Remix’s AI Texture Tools with new models.

In addition, the capabilities of RTX Remix Toolkit are now accessible via REST API, allowing modders to livelink RTX Remix to other DCC tools such as Blender, and generative AI apps such as ComfyUI. NVIDIA is also releasing an SDK for the RTX Remix runtime to allow modders to deploy RTX Remix’s renderer into other applications and games beyond DirectX 8 and 9 classics.

Since RTX Remix Toolkit launched earlier this year, 20,000 modders have experimented with using it to mod classic games, resulting in over 100 RTX remasters in development on the RTX Remix Showcase Discord. By continuing to open up the RTX Remix platform, we aim to enable and inspire modders across the globe to build even more amazing RTX remasters.

RTX Remix Toolkit: Now Open Source

Members of the RTX Remix community have introduced new functionality and features for the RTX Remix Toolkit. By open sourcing the Toolkit, all modders can now contribute new features, tweaks and changes on our Toolkit GitHub.

Following code review, these submissions may be selected to become part of our official Remix releases, bolstering the Toolkit’s capabilities for every Remix modder, giving them more tools to create amazing  mods and remasters of classic games.

To see contributions from other modders, head to the RTX Remix Showcase’s tools channel. And if you’re inspired to make your own Remix enhancement, be sure to submit to our open source GitHub.

RTX Remix’s REST API

Developers can now use the REST API to connect RTX Remix with other applications, including DCC applications like Blender, ComfyUI, and ChaiNNer. While the RTX Remix Toolkit runs in the background, applications can work in lockstep with any of its functions.

REST API is a gateway to the latest technologies, enabling modders to quickly remaster games by adding a huge amount of new functionality based on their needs. Connected applications unlock endless possibilities and allow modders the ability to mass process game assets as well as fine tune the smallest of details. The only limit is the creativity of the artist. 

To demonstrate one functionality of the RTX Remix REST API, we’ve connected RTX Remix with the generative AI ecosystem of ComfyUI, and released the plugins as open source on this GitHub.

 

Generative AI can help quickly remaster game textures in high resolution and with physically accurate materials that work in concert with RTX Remix’s full ray tracing. Save time by upgrading secondary assets with AI, with tools like ComfyUI, to enhance game textures or modified assets.
