What is it?
A collection of Materials and Cloud Volumes for Unreal Engine aimed at replicating a VDB-like actor workflow for highly customizable volumetric skies! From massive vortexes, to distant storm-fronts, from sand storms to wisps we offer a huge variety of stylized and and natural looking clouds in our volume library.
Our CloudScape Actors allow each cloud to be individually placed, moved, scaled,stretched and rotated allowing users to build massive and detailed skies! You can also add per cloud animations as of UPDATE 1
As of Update 3 you we've integrated a tilable cloud function for large scale background clouds you can also edit this function to easily add your own clouds alongside CloudScape Actors. We've also changed the way our detail noise is applied for better and faster visuals! See all the changes here UPDATE 3
As of Update 4 we now have localized volumetric fog material that can be used with static meshes! The fog material can use any volumetric cloud texture and noise distortion available to the cloud actors. These are meant for projects that require smaller scale localized volumetric effects. UPDATE 4
So who is this for?
Both pre-rendered animations and real-time game projects can benefit from CloudScape! While older systems will struggle with a full on volumetric sky our Capture Sky Actor can bake it all down to a much lighter texture that can be used with a skybox! While animation focused projects can take advantage of the fully Volumetric Sky!
IF YOU ARE SOLELY INTERESTED IN THE VOLUMETRIC FOG MATERIALS WE HAVE A STANDALONE VERSION AVAILABLE HERE FOR A LOWER COST WHICH CONTAINS ALL VOLUMETRIC TEXTURES IN THIS PACK - HERE

What's in it?
4 main Blueprint Actors:
CloudScape Base Actor responsible for the rendering of the clouds (supports up to 32 CloudScape Actors)
CloudScape Actor used for individual cloud actors
Capture Sky Actor used to capture a panoramic sky texture for projects designed to work on lower end hardware.
Volumetric Fog Actor an exponential height fog actor with extended settings
Large Volume Asset Library: 53 Cloud Volumes, 13 Tile-able Noise Volumes, 1 Master Cloud Material
A set of 7 Demo Maps
Features: (Please include a full, comprehensive list of the features of the product)
4 BP Actors - for Sky Rendering, Cloud Asset and Sky Baking + Fog
53 Volumetric Cloud Textures
13 Volumetric Tillable Noise Textures
Number of Materials: 4 + 7 Instances
Number of Textures: 73
Number of Blueprints: 4
Supported Development Platforms: Windows PC
Important/Additional Notes:
> In UE5 Raytraced shadows do not work on volumetric fog so you will need to disable these to get proper shadows
> Again the volumetric fog by default has a limited draw distance so it is meant for up close visuals
> The fake self shadow needs a directional atmospheric light to work properly
> Volumetrics will only display correctly in projects with Shadow Quality settings set to High or higher
这是什么？
一个针对虚幻引擎的材料和云卷的集合，旨在复制一个类似vdb的演员工作流，用于高度可定制的体积天空！从巨大的漩涡，到遥远的风暴锋，从沙尘暴到缕缕，我们在我们的卷库中提供了各种各样的风格化和自然的云。
我们的CloudScape Actors允许每个云单独放置，移动，缩放，拉伸和旋转，允许用户构建大量和详细的天空！您还可以在UPDATE 1中添加每个云动画
在更新3中，我们为大规模的背景云集成了一个可调整的云功能，你也可以编辑这个功能，轻松地在CloudScape Actors旁边添加你自己的云。我们还改变了细节噪点的应用方式，以获得更好更快的视觉效果！查看所有更改在这里更新3
在更新4中，我们现在有了局部体积雾材料，可以与静态网格一起使用！雾的材料可以使用任何体积云纹理和噪音失真可用的云演员。这些适用于需要较小规模局部体积效应的项目。更新4
这是给谁的？
预渲染动画和实时游戏项目都可以从CloudScape中受益！虽然旧的系统将与一个完整的体积天空斗争，我们的捕捉天空演员可以把它烤成一个更轻的纹理，可以与天空盒一起使用！而动画为重点的项目可以充分利用体积天空！
如果你只是对体积雾材料感兴趣，我们有一个独立的版本，可以在这里以较低的成本提供，它包含了这个包中的所有体积纹理-这里
技术细节
里面有什么？
4个主要的蓝图参与者：
CloudScape基础Actor负责云的渲染（支持多达32个CloudScape Actor）
CloudScape Actor用于单个云Actor
Capture Sky Actor用于为设计用于低端硬件的项目捕获全景天空纹理。
Volumetric Fog Actor是一个具有扩展设置的指数高度雾Actor
大卷资产库：53个云卷，13个可平铺噪声卷，1个主云材料
一套7个演示地图
产品特性：（请包括一份完整、全面的产品特性清单）
4 BP演员-天空渲染，云资产和天空烘烤+雾
53体积云纹理
13体积可Tillable噪声纹理
材料数量：4 + 7实例
纹理数量：73
蓝图数量：4
支持的开发平台：Windows PC
重要的/其他说明:
在UE5中，光线追踪阴影对体积雾不起作用，所以你需要禁用这些来获得合适的阴影
再一次，体积雾默认有一个有限的绘制距离，所以它意味着近距离的视觉效果
假的自我阴影需要一个定向大气光来正常工作
> Volumetrics只会在阴影质量设置为高或更高的项目中正确显示
