Universal Render Pipeline


Your game's environment is boring. Fix it with Buto. Lightning-fast, infinitely customizable volumetric lighting and fog. Set up in 60 seconds. Join 515+ game devs already experiencing the future of volumetrics.




  1. Physically-based: Our volumetric lighting and fog accurately renders atmospheric particles and light scattering using algorithms described in leading technical papers and strategies from major AAA studios.
  2. Volumetric Lighting and Shadow: Objects realistically occlude lighting from interacting with the fog, keeping your fog grounded in your scene.
  3. Fast: Optimized, high-performance rendering with intelligent depth-aware upscaling (~0.7ms on an Nvidia 1080 desktop equivalent).
  4. Volumetric Noise: Built-in customizable volumetric noise gives texture to the particle distribution. Choose from 5 configurable volumetric noise styles or import your own texture for the ultimate control.
  5. Atmospheric Height Fog: Particle density exponentially decreases over height, resulting in realistic fog attenuation over altitude.
  6. Long-Range Visual Consistency: Toggleable analytic height fog can be rendered behind local volumetric fog to guarantee visual realism over long distances.
  7. Stylized Fog Options: Achieve your artistic vision with color ramps, simple color adjustments, and light and shadow intensity sliders.
  8. Additional Lights: Illuminate the fog with volumetric point lighting.
  9. Fog Density Masks: Add or erase volumetric fog using Fog Density Masks
  10. Temporal Anti-Aliasing: Improved quality for high density fog with optional Temporal Anti-Aliasing.
  11. Integrated with the Volume Component System: Seamlessly tie Volumetric Fog into your workflow with Unity's Volume Component system. Set Global Fog parameters and local Box and Sphere Volume parameters with seamless blending between Fog Volume settings.

Tested On...

Vulkan, OpenGL, Direct3D 11, Direct3D 12


  1. Transparent materials are not fully supported. Objects using transparent materials are rendered after the fog pass and will not receive the effects of the fog.
  2. VR is not supported.
  3. Orthographic perspective is not supported.
  4. Volumetric point lighting does not support shadow attenuation.
  5. WebGL is not supported.
