The Gnomon Workshop – Creating Volumetric Effects with Houdini

在这篇关于在 Houdini 中创建体积效果的介绍中，高级 VFX 艺术家 Robby Branham 介绍了使用 VDB、元球和 Houdini 的 Cloud FX Shelf 工具等技术创建体积的原则。研讨会详细介绍了创建云的基本设置，然后将其用作创建大型 VDB 库的模板——适用于所有通用 3D 环境。

这个全面的 12 章研讨会涵盖了静态和动画体积系统的创建，以实现令人信服的行业标准云、雾、霾和烟雾效果。Robby 使用几何和 SOP 工作流程的快速有效的方法在创建关键体积形状时提供了最终控制，并且在创建各种环境体积时可以广泛使用他通过 Volume VOP 添加微观细节的技术。

还解释了封面艺术的创作，从地形布局和大气元素的应用，到照明、渲染和最终合成。讨论了 Mantra 和 Redshift 的渲染设置，以及将体积从 Houdini 导出到 Maya 的工作流程。Robby 的静态云、雾、雾和薄雾体积的 VDB 库也可以通过此研讨会下载，以及 Houdini 文件

Title: The Gnomon Workshop – Creating Volumetric Effects with Houdini

Info:
In this introduction to creating volumetric effects in Houdini, Senior VFX Artist Robby Branham covers the principles of creating volumes using techniques including VDBs, metaballs, and Houdini’s Cloud FX Shelf tools. The workshop details an essential setup for creating clouds, which is then used as a template to create a large VDB library — useful for all general-purpose 3D environments.

This comprehensive, 12-chapter workshop covers the creation of both static and animated volume systems for convincing, industry-standard cloud, fog, haze, and smoke effects. Robby’s fast and efficient methods using both geometry and SOPs workflows give ultimate control when creating key volumetric shapes, and his techniques for adding micro details with Volume VOPs can be used extensively when creating a variety of environmental volumes.

The creation of the cover artwork is also explained, from the terrain layout and application of atmospheric elements, through to the lighting, rendering, and final composite. Rendering setups for both Mantra and Redshift are discussed, plus the workflow for exporting volumetrics from Houdini to Maya. Robby’s VDB library of static cloud, haze, fog, and mist volumes can also be downloaded with this workshop, along with the Houdini files,
