Expanse is a state of the art volumetrics tool for HDRP that gives you the power to author beautiful skies, clouds, and fog banks. In as little as 15 minutes, you can create compelling and interactive atmospheres---earthly, mythical, and stylized.

The rendering and authoring strategies that Expanse uses are based on the most recent production-focused papers coming out of conferences like SIGGRAPH and EGSR. Every component of Expanse is physically-based, allowing for unprecendented realism and consistency across different lighting conditions.

Expanse is a fully dynamic system that can be adjusted in realtime, with no precomputed lookups that slow down the authoring process. Things like cloud coverage, fog density, and time of day can easily be animated with keyframes or scripted to create different weather scenarios. All the changes you make are visible in the editor, so you can tweak your sky without ever having to enter play mode.

Expanse is also performance-optimized for realtime applications. You can pick and choose between a number of quality/performance tradeoffs to optimize your sky to hit your frame time requirements. For reference, on a last-gen 2080 Ti, Expanse can render an entire sky with volumetric atmosphere, clouds, and fog in under 0.7ms.

While not necessarily VR-first, Expanse does support single pass instanced VR. Support is still experimental in nature, but will gradually transition to being labeled "production ready" as more users test it. Expanse only supports the VR platforms that HDRP supports.

If you need to make modifications to Expanse, no problem---you'll receive all C# scripts and shaders uncompiled when you purchase Expanse.

As a note: I'm an independent developer with no QA team, so I appreciate your patience regarding bug fixes and support!

Expanse is licensed on a per-seat basis. As provided for by the asset store EULA, you will need to purchase a license for each individual who will use Expanse. For details refer to the asset store EULA or EULA FAQ.


浩瀚是HDRP的最先进的体积测量工具,让您能够编写美丽的天空,云和雾银行。在短短15分钟内,你就可以创造引人注目的互动氛围——世俗的、神话的和程式化的。

以太所使用的渲染和创作策略是基于最近在SIGGRAPH和EGSR等会议上发表的以生产为重点的论文。《浩瀚宇宙》的每个组件都是基于物理的,允许在不同的光照条件下实现前所未有的现实主义和一致性。

浩瀚是一个完全动态的系统,可以实时调整,没有预先计算的查找,减慢创作过程。像云量、雾密度和一天中的时间可以很容易地用关键帧动画或脚本来创建不同的天气场景。你所做的所有改变都在编辑器中可见,所以你可以调整你的天空,而不必进入播放模式。

对实时应用程序也进行了性能优化。您可以在许多质量/性能权衡中进行选择,以优化您的天空,以满足您的帧时间要求。作为参考,在最后一代2080 Ti上,浩瀚可以在0.7毫秒内渲染整个天空,包括大气、云和雾。

虽然不一定是VR优先,但《浩瀚》确实支持单通道实例VR。支持在本质上仍然是实验性的,但随着更多用户的测试,它将逐渐转变为“生产就绪”。苍穹只支持HDRP支持的VR平台。

如果你需要修改浩瀚,没有问题-你会收到所有的c#脚本和着色器未编译当你购买浩瀚。

注:我是一个独立开发人员,没有QA团队,所以我感谢你的耐心修复bug和支持!

《浩瀚》是按座位收费的。根据资产存储EULA的规定,您将需要为每个将使用浩瀚的人购买许可证。具体请参见资产存储EULA或EULA FAQ。
