The Gnomon Workshop – Creating Procedural Environments in Gaea and Houdini with Rasha Shalaby

Quadspinner 的 Gaea 程序性质使 3D 艺术家和哑光画家能够使用其强大的工具制作令人印象深刻的逼真环境。将 Gaea 合并到 Houdini 工作流程中，Rasha Shalaby — 一位环境艺术家和哑光画家，在电影、电视和游戏电影的视觉特效方面拥有 20 多年的经验 — 揭示了如何创建地形资产，例如通常更难的冰崖和岩石地形仅通过高度场模拟来实现。

在这个 3.5 小时的研讨会中，Rasha 演示了如何使用 Gaea 中的各种侵蚀和扭曲技术创建几何图形，以及如何提取数据以帮助创建资产的纹理和数据贴图。她分享了如何将纹理和贴图导出到 Houdini 以用于外观开发和照明阶段，并展示了如何在 Houdini 中为环境建立外观、照明设置和相机。渲染是在 Arnold 中设置的，以获得最终的最终外观。

Rasha 快速浏览了 Houdini 的一些用于创建复杂分层表面的顶级工具——重点介绍那些有助于保持悬崖岩石外观的工具。还包括如何创建环境的 360 度全景的概述，展示了 Rasha 如何引入她的地平线渲染，并在 Photoshop 中进行了一些绘画、蒙版和调整，能够在以后使用生成的图像为最终渲染点亮场景。

这个研讨会包含了 Rasha 从 20 多年的行业工作中学到的技巧和窍门。订阅者包括一系列有用的项目文件，包括网格、纹理文件和研讨会中使用的 Houdini 项目。

Title: The Gnomon Workshop – Creating Procedural Environments in Gaea and Houdini with Rasha Shalaby

Info:
The procedural nature of Gaea by Quadspinner empowers 3D artists and matte painters to craft impressive and realistic environments with its powerful tools. Incorporating Gaea into a Houdini workflow, Rasha Shalaby — an Environment Artist and Matte Painter with over 20 years of experience in VFX for film, TV, and game cinematics — uncovers how to create terrain assets such as icy cliffs and rocky terrains that are usually harder to achieve through height-field simulations alone.

In this 3.5-hour workshop, Rasha demonstrates how to create geometry using various erosion and warp techniques in Gaea, as well as how to pull data to help create textures and data maps for assets. She shares how to export textures and maps into Houdini for the lookdev and lighting stage, and reveals how to establish the look, lighting setup, and cameras for the environment in Houdini. The renders are set up in Arnold for the ultimate final look.

Rasha offers a quick tour through some of Houdini’s top tools for creating complex, layered surfaces — with a focus on those that help to maintain the rocky look of cliffs. An overview of how to create a 360-degree panorama of the environment is also included, showing how Rasha brings in her renders of the horizon and, with some painting, masking, and adjustments in Photoshop, is able to use the resulting image to later light the scene for the final render.

This workshop is packed with Rasha’s tips and tricks learned from more than 20 years working in the industry. Included for subscribers is a collection of helpful project files, including the meshes, textures files, and the Houdini project used in the workshop.
