Houdini Terrain Techniques Creating Landscapes

在这个标题中，高级视觉效果艺术家 Robby Branham 对 Side FX 的 Houdini 17 中的地形工作流程进行了广泛的概述。深入显示了 Houdini 的高度场节点，以演示如何从头开始创建地形。掩蔽技术用于创建独特的分层表面。演示了实例化和地形复制技术以创建大型景观。创建了几种不同类型的景观，包括雪山、流星坑、农业梯田等。地形的纹理和阴影是在 Houdini’s Mantra 内部完成的，Redshift 着色网络用于为地形表面添加颜色和微细节。Houdini 的内置合成器被教导使用来自侵蚀节点的内置属性为高度场创建详细的纹理贴图。Robby 演示了 Earth Explorer 的卫星数据以及如何根据现有的现实世界数据创建地形。涵盖了树木散射和随机化工作流程，该工作流程利用高度场节点的属性来补充景观的自然外观。

In this title, Senior Visual Effects Artist Robby Branham provides a broad overview of the terrain workflows in Side FX’s Houdini 17. Houdini’s heightfield nodes are shown in depth to demonstrate how to create terrains from scratch. Masking techniques are utilized to create unique and layered surfaces. Instancing and terrain duplication techniques are demonstrated to create large landscapes. Several different types of landscapes are created including a snowy mountain, a meteor crater, agricultural terracing and more. Texturing and shading the terrain is accomplished inside of Houdini’s Mantra, and Redshift shading networks are used to add color and micro details to the terrain surfaces. Houdini’s built in compositor is taught to create detailed texture maps for the height field using the built in attributes from the erosion nodes. Robby demonstrates Earth Explorer’s satellite data and how to create terrains from existing real world data. A tree scattering and randomization workflow is covered that takes advantage of the Height Field node’s attributes to complement the natural look of the landscapes. Robby creates the cover art terrain from scratch in the tutorial through mesh creation, texturing, shading, rendering, and layout. The cover art Nuke composite is broken down throughout the entire shot process, from concepting, previsualization, asset creation, terrain creation, layout, lighting, rendering and final compositing.
