CloudScape Volumetric Cloud & Fog Library 适配UE4.26，4.27
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

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

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
它是什么？
虚幻引擎的材质和云卷集合，旨在为高度自定义的体积天空复制类似于VDB的演员工作流程！从巨大的漩涡到遥远的风暴前沿，从沙尘暴到缕缕白云，我们的体积库中提供了大量风格化和自然外观的云朵。
我们的 CloudScape Actors 可对每朵云进行单独放置、移动、缩放、拉伸和旋转，让用户可以构建庞大而细致的天空！从更新 1 开始，您还可以添加每朵云的动画效果。
从更新 3 开始，我们为大型背景云集成了可倾斜云功能，您也可以编辑此功能，轻松地在 CloudScape Actors 中添加自己的云。我们还更改了细节噪点的应用方式，以获得更好更快的视觉效果！点击此处查看所有更改 更新 3
从更新 4 开始，我们现在有了可与静态网格一起使用的局部体积雾化材质！雾化材质可使用云演员可用的任何体积云纹理和噪点变形。这些材料适用于需要较小规模局部体积效果的项目。更新 4
这是为谁准备的？
预渲染动画和实时游戏项目都能从 CloudScape 中受益！虽然旧系统在处理全体积天空时会很吃力，但我们的 "捕捉天空代理 "可以将其全部烘焙为可与天空盒一起使用的更轻质纹理！以动画为主的项目可以利用完全体积天空！
如果您只对体积雾材质感兴趣，我们还提供了一个独立版本，其中包含本软件包中的所有体积纹理，价格更低 - 点击此处

重要/附加说明：
> 在 UE5 中，光线追踪阴影对体积雾不起作用，因此您需要禁用这些功能才能获得合适的阴影。
> 同样，默认情况下体积雾的绘制距离有限，因此它适用于近距离视觉效果
> 假自体阴影需要定向大气光才能正常工作
> 只有在阴影质量设置为 "高 "或更高的项目中，才会正确显示体积阴影
