第117篇 VDB结合噪波制作抽象有机体及硬表面模型vdb and noise in houdini

本教程讲解如何使用 VDB 以及 Houdini 中提供的各种程序化噪波贴图生成各种有机、抽象的形状和结构,例如生成各种岩石、悬崖,甚至还原 Megascans 资产库里的高精度悬崖。还介绍了如何将细节从高模烘焙到低模。最后,还将讲解如何使用 VDB 和噪波贴图制作硬表面模型。

 

教程简介:

 

Welcome to VDB and noise in Houdini.

 

This series will teach you how to generate a variety or organic and inorganic shapes and structures using VDB and the various procedural noise maps and textures available in Houdini.

 

Over the course of the training we will see how generate a variety of rocks, cliffs and even recreate a Megascans cliff. We will also take a look at how to bake the details from the high res geometry to a low res model.

 

Towards the end we shall also take a look at how to create hard surface models using VDB and Noise maps.

 

章节目录:

 

  1. VDB basics – A look at the basic vdb tools required for modeling which include, vdb from polygons, vdb reshape, vdb smooth, volume vop, delete small parts and sharpen
  2. Noise distortion and ramps – Applying noise maps ,unified and turbulent noise, distorting noise maps and controlling noise using ramps
  3. Basic rock shapes – making some basic rock shapes using a combination of alligator noise, cellular noise and some noise distortion.
  4. More rock shapes – Building stepped rocks and a cluster of rocks using a combination of noise maps
  5. Megascans rock – recreating a megascans cliff asset using procedural noise maps
  6. Cliffs – building a cliff structure by combining a cluster of rock shapes and further modification using volume vop
  7. Material Fracture – making a rock using a combination of material fracture and noise maps in a volume vop
  8. VDB color – extracting color and other attributes from a vdb to polygon level.
  9. Baking – learning how to bake a high res mesh to a low poly object and building a shader in substance painter
  10. Volume masking – Masking a volume vop using a secondary volume field
  11. Hard surface modeling – learning how to mirror noise maps and making a sci-fi model using noise maps and ramps 
  12. Uv mapping and vdb – using uv maps and polar coordinates to modify noise maps in a vdb
