Introducing TPGI: Performant, Realtime, Global illumination!
Greetings, devs and creators! We are excited to introduce a groundbreaking system - TPGI (Trace Projection Global Illumination). TPGI isn’t merely another barely Realtime solution; it’s a paradigm shift in crafting immersive, awe-inspiring experiences for your players.
TPGI: Setting a New Standard
TPGI represents the pinnacle of whats possible, delivering AAA-level realism to your Roblox creations. It’s the essence of excellence, a catalyst that will elevate your games beyond the ordinary and into the extraordinary!
TPGI Highlights
Probes for Unparalleled Realism: TPGI employs a simple system, utilizing raytraces generated from a network of probes, to ensure fast light bouncing that can dynamically respond to your game’s environment.
Low Latency Magic: With lightning-fast updates, all probes smoothly refresh in 2 seconds or less, ensuring real-time performance for an immersive experience, regardless of your game’s pace.
Version Update: RE1 After two years of relentless research and development, we are proud to introduce RE1, the first official version of TPGI, marking a significant milestone in our journey.
Pro-Level Lighting Magic: TPGI masterfully blends your existing scene lighting with lighting fast raytraced projection, delivering convincing light falloff and top-tier illumination, imparting a cinematic touch to your Roblox worlds.
Optimized for Next Gen Performance: We understand the importance of performance. TPGI is engineered to operate seamlessly, even with impressively high settings, catering to players across a spectrum of devices.
Ready to Rumble: TPGI is on the verge of going live, and we are thrilled to announce that ULTEAM has secured the first official license of TPGI, proving its ready for prime time!
Craft Pro-Level Environments: With TPGI, you have the power to craft immersive and atmospheric settings that will captivate your players. From mysterious dungeons that cloak everything in the distance with thick shadows to sun-drenched outdoor paradises bursting with vivid coastal streets and lush greens amplified by the sun, TPGI takes player experiences to an entirely new dimension.
Dev-Friendly Integration: We’ve got your back! TPGI offers user-friendly near drag-and-drop integration and comprehensive documentation, ensuring accessibility to developers and teams striving for a professional edge in their projects.

That’s what I’m saying… It looks like jus regular lighting but configured to be darker, and then branded as some next-gen ground breaking system.
Thats what global illumination is, You are simulating how the scene should be casting light color then projecting that where an ambient would be. The ambient in all screenshots is (0,0,0), TPGI adds in ambient light using probes based on the lighting and scenery around you. A raytrace is performed which is used to figure out the final color then the lighting is checked to bump brightness or dampen it depending on if a probe is lit or not. That last point is going to change in the next version of tpgi, it will get physically accurate brightness added since the current solution couldnt be physically accurate for performance reasons and we found a new solution.
The ground breaking part isnt in the visuals (though they are pretty if you pay attention to how light moves), the ground breaking part is in the tech behind it. TPGI’s raytracing is capable of 256 rays per second with 8 bounces relatively smoothly in simple scenes, this is enough to in theory render with the tech. TPGI performs 64 rays per second with 4 bounces (in the screenshots).
here is a demo of the tracer at 512 rays per second with 16 bounces, my FPS dropped to about 20ish when the simulation started then slowly dropped as more beams were generated to debug with.
