Showcasing Nyx Prime's PBR model[1]

Physically Based Rendering (PBR) is a computer graphics rendering technique that takes into account material properties of objects to mimic how light behaves in reality. A prominent example of this in WARFRAME is seen on metallic objects and surfaces which use PBR to mimic the harsh, reflective surfaces of metal when light bounces off them.

WARFRAME's Evolution Engine started using PBR in Update 15.0 (2014-10-24).[2]

Details[]

Materials that are have not gone under the PBR treatment will look more "dull" or "flat" compared to their PBR counterparts and will not be drastically affected by environmental lighting.[3][4]

As of Update 31 (2021-12-15), for rendering skies and atmospheres like in Landscapes, the engine uses a Physically Based Atmospheric Model to model how light scatters throughout the atmosphere.[5][6][7]

Patch History[]

Update 31.6 (2022-06-09)

Lighting Changes:

We have made the following changes to lighting to improve how it interacts with details in open landscapes!

  • Separated sky lighting from the rest in lightmaps, resulting in improved lighting quality because samples coming from opposite directions will no longer cancel each other out.
    • Lighting at night will now pop much more! Prior to this change, everything would be tinted in dark blue. Now, each lighting source will have much more vibrance in contrast to the dark backdrop of night.
    • Lighting during the day will now have a lot more textural details especially when viewing things at distance. Prior to this change, details would tend to get lost at a distance and resemble more clay-like, without any grit or grain to it.
  • Added sun bounce to the enhanced graphics engine.
  • Enhanced graphics engine also offers more detail at a distance.

Lighting Improvements

Firstly, this is a sweeping change across the entire game! Please be conscious that some areas may appear overly or underlit. We will work to fix up any rough looking spots - feel free to send screenshots are way in bug threads throughout the appropriate subforums.

With Inaros, the sands of old have been swept away from U18 Warframe leaving behind a newer, more vibrant U18.5 Warframe. In many respects, 18.5 is a remastered, more HD version of Warframe with months of technical graphical improvements and artistic relighting of many parts of the game (and more to come in subsequent updates). On top of these changes are across the board rendering performance improvements we hope you'll enjoy, keep in mind that your particular hardware may benefit more and benefit less depending on your GPU, resolution and preferred graphics settings.

  • Lighting textures have been reengineered to reduce square compression artifacts and ugly color banding. You may have seen me point this out on past Devstreams.
  • All PBR materials have been recompressed with a more accurate format, new and subtle details are visible on your PBR'd Warframes, gear and in the environment.
  • Reflection Probes have been built through many areas of the game, grounding PBR materials with more accurate lighting.
  • Character and weapon lighting includes more accurate 'dual specular' lighting which means metallic surfaces are more realistic and fancy looking.
  • HDR rendering has been switched to a compact 32bit format which has improved HDR rendering performance for a wide range of GPUs.
  • Tonemapping has been adjusted to use more of the range of lighting content in the game, images have more detail, particularly richer in the darks.
  • Motion Blur and Depth of Field have been re-engineered to run faster and look better, fast moving and defocused objects no longer appear 'cut out' on their silhouettes.
  • Draw order optimizations have been applied to every object in the game, which improves overall performance, particularly in worst-case scenarios.
  • Atmospheric fog effects are now rendering in a separate lighting pass, allowing richer particle effects at distance without being 'erased' by atmosphere.
  • Particle lighting has been improved to more accurately represent the local lighting environment.
  • Wind force modelling on many particle systems increase realism as various environmental particles now respond to explosive forces and Warframe powers – you've also probably seen us showcase this in our most recent Devstream.
  • Bloom system has been softened and made more seated in the scene. The burnt-out look is replaced with a more subtle and gentle sci-fi glow.
  • Physics collision, performance and stability have all been improved, as a long-awaited upgrade of Warframe PhysX libraries has been completed.
General Changes
  • The Quanta, Mutalist Quanta, and Volt have all been given a PBR update.
  • Various Dojo elements, Darvo’s banner, and ice elemental hazards have been given a PBR update.
