Houdini制作三维自然地形场景 Houdini Terrain Techniques

本套CG教程,已翻译成中文,请享用。

学习Houdini 17制作自然地形的方法,高阶教程,比如包含图层之间的遮罩使用,不同地形之间的衔接,地形预设制作,RedShift灯光渲染和最后的Nuke合成等等,包含Houdini工程项目源文件。

在这个Houdini教程中,高级视觉效果艺术家Robby Branham对Side FX Houdini 17中的地形工作流程进行了全面概述.Houdini的高度场节点进行了深入展示,以展示如何从头开始创建地形。如创建不同类型的景观,包括雪山,流星陨石坑,农业梯田等。然后在Houdini的Mantra内部完成纹理和阴影着色,Redshift着色网络用于向地形表面添加颜色和微观细节。教程涵盖了从概念设计,预可视化,资产创建,地形创建,布局,照明,渲染和最终合成。

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.
