We update Buto often with improvements and bug fixes
Buto now supports orthographic projection.
Improved rendering quality
Various performance optimizations with up to ~25% faster rendering.
The editor now offers quality presets.
Buto now supports spotlights.
We've introduced a new directional lighting setting. With directional lighting, you can now tint the fog based on the position of your main directional light in the scene.
We've improved the editor GUI. The connection between the Color Influence and the Individual and Ramp color overrides is now more obvious.
Immerse players with realistic volumetric fog for Unity
Buto is not just a volumetric fog and lighting asset, it's a powerful tool that can elevate the atmosphere of your game to a whole new level.
For amateur developers, Buto offers a user-friendly interface that allows you to easily add volumetric fog and lighting to your game with just a few clicks. With the built-in customizable volumetric noise and color ramps, you can add texture and depth to your fog, making it look more realistic and believable. The fog density masks feature allows you to add or erase volumetric fog in specific areas, giving you even more control over the look and feel of your game.
For expert developers, Buto offers a wide range of advanced features that allow you to take your game's atmosphere to the next level. The physically based volumetric fog and lighting system uses algorithms described in leading technical papers and strategies from major AAA studios, providing a level of realism that is unmatched by other assets. The volumetric lighting and shadow feature ensures that objects in your scene realistically occlude lighting and cast shadows, grounding your fog in the scene. Additionally, Buto offers support for point lights and spotlights, giving you even more ways to illuminate your fog and create stunning visuals.
Buto can be used in a variety of use cases in your game, from adding realism to outdoor environments, such as a misty forest or a foggy mountain, to creating an eerie atmosphere in a horror game. The volumetric noise feature can be used to add texture to the particle distribution, making the fog look more natural. The atmospheric height fog feature makes the particle density exponentially decreases over height, resulting in realistic fog attenuation over altitude. The Long-Range Visual Consistency feature can be used to guarantee visual realism over long distances. The Stylized Fog Options feature allows you to achieve your artistic vision with color ramps, simple color adjustments, directional lighting controls, and light and shadow intensity sliders.
Buto is a must-have asset for any Unity developer looking to create immersive and believable environments in their game. With its advanced features and user-friendly interface, Buto is perfect for both amateur and expert developers. And with our 100% satisfaction guarantee, you can trust that Buto will meet your needs and exceed your expectations.
This asset offers tons of powerful features
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.
Volumetric Lighting and Shadow:
Objects realistically occlude lighting by interacting with the fog, keeping your fog grounded in your scene.
Fast:
Optimized, high-performance rendering with intelligent depth-aware upscaling (~0.7ms on an Nvidia 1080 desktop equivalent).
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.
Atmospheric Height Fog:
Particle density exponentially decreases over height, resulting in realistic fog attenuation over altitude.
Long-Range Visual Consistency:
Toggleable analytic height fog can be rendered behind local volumetric fog to guarantee visual realism over long distances.
Stylized Fog Options:
Achieve your artistic vision with color ramps, simple color adjustments, and light and shadow intensity sliders.
Additional Lights:
Illuminate the fog with volumetric point lighting.
Fog Density Masks:
Add or erase volumetric fog using Fog Density Masks
Temporal Anti-Aliasing:
Improved quality for high-density fog with optional Temporal Anti-Aliasing.
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.
Other Unity developers already use Buto in their projects
Hopper's Cabin by VHS Knight (itch.io)
We tested Buto across the major graphics APIs to ensure compatibility
Vulkan, OpenGL, Direct3D 11, Direct3D 12
Buto offers support for almost every use case
Compatible with both Perspective Projection and Orthographic Projection.
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. You can override this behavior using the included Buto.hlsl shader include (see Demo Resources for example usage).
VR SPI is not supported.
用于UNITY URP的体积雾和体积照明
Buto是你一直想要的体积化雾气。
Buto是Unity URP的终极体积雾和照明资产，它能让你的游戏环境变得更加生动。
用雾蒙蒙的森林或雾蒙蒙的山脉为你的户外场景增加真实感，在你的恐怖游戏中创造阴森恐怖的气氛，或者用可定制的体积噪音为你的游戏氛围增加深度和质感。
有了Buto，你可以实现你的艺术愿景，将你的游戏氛围提升到新的高度。体验体积计量学的未来，用Buto使你的游戏脱颖而出。
我们经常更新Buto，进行改进和错误修复
Buto现在支持正射投影。
改进了渲染质量
各种性能优化，渲染速度提高~25%。
编辑器现在提供了质量预设。
Buto现在支持聚光灯。
我们引入了一个新的方向性照明设置。有了方向性照明，你现在可以根据场景中主要方向性灯光的位置来给雾气着色。
我们改进了编辑器的图形用户界面。颜色影响与单独和斜坡颜色覆盖之间的联系现在更加明显。
用Unity的逼真的体积化雾气让玩家沉浸其中
Buto不仅仅是一个体积雾和照明资产，它是一个强大的工具，可以将你的游戏氛围提升到一个全新的水平。
对于业余开发者来说，Buto提供了一个友好的界面，让你只需点击几下就可以轻松地在游戏中添加体积雾和照明。通过内置的可定制的体积噪声和颜色斜面，你可以为你的雾气添加纹理和深度，使其看起来更加真实可信。雾密度掩码功能允许你在特定区域添加或擦除体积雾，让你对游戏的外观和感觉有更多的控制。
对于专家级的开发者，Buto提供了广泛的高级功能，使你能够将你的游戏氛围提升到新的水平。基于物理的体积雾和光照系统采用了主要AAA工作室的领先技术论文和策略中描述的算法，提供了其他资产无法比拟的真实度。体积照明和阴影功能确保你的场景中的物体真实地遮挡照明和投射阴影，使你的雾气在场景中接地。此外，Buto还提供了对点光源和聚光灯的支持，让你有更多的方式来照亮你的雾气，创造出令人惊叹的视觉效果。
