BeamNG.drive\u2019s latest update contains something quite interesting buried in its graphics overhaul: the game now renders its final image using tone mapping technology developed by Polyphony Digital for Gran Turismo 7.<\/p>\n

The developers explicitly credit Gran Turismo 7 in their documentation while linking directly to Polyphony Digital\u2019s presentation and code, where it was spotted by GTPlanet user nolifebr<\/a> and posted in our forums.<\/p>\n

Version 0.39, released on July 29<\/a> and described by BeamNG as the biggest update in the game\u2019s history, replaces its previous ACES-based tone mapper (derived from the film industry\u2019s widely used Academy Color Encoding System) with what the studio\u2019s official documentation<\/a> plainly calls \u201ca Gran Turismo 7 tone mapping\u201d.<\/p>\n

That should be familiar to long-time GTPlanet readers: it\u2019s the same \u201cDriving Toward Reality\u201d talk delivered by three Polyphony engineers at SIGGRAPH 2025, which we covered in detail in our article \u201cWhy Gran Turismo 7\u2019s Graphics Look So Different From Other Games<\/a>\u201c.<\/p>\n

Alongside the slides, Polyphony published a standalone C++ sample implementation of the GT7 tone-mapping operator under the MIT License, effectively inviting other developers to study and use it.<\/p>\n

Less than a year later, one of them has.<\/p>\n<\/p>\n

Polyphony Digital has a long history of presenting its research at academic conferences like SIGGRAPH and CEDEC, but seeing another commercial game adopt that work (and openly say so) is notable.<\/p>\n

The timing is fitting, as Polyphony\u2019s HDR work has been in the spotlight again lately.<\/p>\n

Just last weekend, we covered the studio\u2019s \u201cBeyond HDR\u201d presentation at CEDEC<\/a>, where GT7 was demonstrated on a prototype Sony display sustaining more than 10,000 nits. The same engineers behind that session (Kenichiro Yasutomi, Kentaro Suzuki, and Hajime Uchimura) were the presenters of the SIGGRAPH talk whose work now lives inside BeamNG.<\/p>\n

Of course, BeamNG.drive is coming to PlayStation 5 in 2026<\/a>. When it arrives, it will be rendering its image with Gran Turismo technology, on Gran Turismo\u2019s home console.<\/p>\n

What Tone Mapping Actually Does<\/p>\n

If you\u2019ve never heard the term before, tone mapping translates the enormous range of brightness and color produced by a game\u2019s renderer into the smaller range a display can actually reproduce.<\/p>\n

A game engine like BeamNG\u2019s (or GT7\u2019s) calculates lighting internally using real-world values, where the sun is tens of thousands of times brighter than a shaded wall. No television can show that, so tone mapping is one of the final steps in forming the image. It compresses all of that light into something that looks natural on your display, whether that\u2019s an old SDR monitor or a modern HDR TV.<\/p>\n

How the GT7 Method Works<\/p>\n

Polyphony\u2019s approach is built around a simple idea: handle brightness and color separately, so that adjusting one doesn\u2019t ruin the other.<\/p>\n

The system converts the image into a special format modeled on human vision, where a pixel\u2019s brightness and its color are stored independently. That allows it to preserve the identity of saturated colors much more effectively as brightness rises. A red brake light is far less likely to drift toward orange, although the very brightest colors are still gradually desaturated as they approach the display\u2019s limit.<\/p>\n

From there, a couple of finishing touches shape the final image. Polyphony blends a controlled amount of the conventional per-channel result back in, retaining some of the camera-like color response viewers are accustomed to. And the curve uses a highlight \u201cshoulder\u201d to roll intense values off toward the display\u2019s peak, retaining more gradation in bright areas before the output eventually reaches its hard limit.<\/p>\n

The practical payoff, and a benefit BeamNG highlights in its own documentation, is consistency.<\/p>\n

The GT7 tone mapper produces a closely matched overall appearance across SDR and HDR, while allowing HDR displays to retain brighter highlights and a wider contrast range, adapting its curve to the output mode and display brightness it\u2019s configured for. <\/p>\n

Artists can author lighting once using physical values, while BeamNG\u2019s exposure, tone mapping, and output pipeline translates that lighting correctly across SDR and HDR displays. The documentation makes this explicit, telling game modders to always use real-world values and to stop compensating for the limits of SDR screens.<\/p>\n

Alongside the new tone mapper, version 0.39 also adds HDR10 and scRGB output to BeamNG.drive for the first time, along with a physically correct light falloff model. Anyone who has followed Polyphony\u2019s decade-long HDR crusade will recognize the whole philosophy: build the lighting correctly, and let the display technology catch up.<\/p>\n

Polyphony Digital has always positioned its conference presentations as contributions to the wider graphics community, and BeamNG\u2019s adoption is the clearest proof yet that community is paying attention.<\/p>\n

Now we just need to get Polyphony Digital to use BeamNG\u2019s damage model\u2026<\/p>\n
