## Houdini FX 课程：创建雪崩特效装置 本课程将详细介绍如何设置一个逼真的雪崩特效装置。课程时长超过 5 小时，涵盖了从基础到高级的各项技术。 **先决条件：** * 具备 Houdini 的基本操作知识。 * 推荐完成“Master Houdini FX”课程，以打下坚实的 Houdini 基础。 **课程特点：** * **快节奏教学：** 侧重于必要知识点的讲解，不赘述基础节点的功能，旨在节省时间。 * **提供素材：** 所有课程视频均配有可下载的 Houdini hip 文件和必要的资产。 * **渲染器兼容：** 提供 Redshift 和默认 Mantra 渲染器的场景文件，方便不同用户选择。 **课程内容概览：** 1. **2.5D 场景构建：** 分析用于创建雪崩特效的静止图像，讲解视差（parallax）的概念及其在模拟动态摄影中的应用。 2. **粒子模拟：** 利用粒子系统模拟大量粘合在一起、如同积雪般沿着山坡滚动的粒子群。 3. **高级特效：** * 添加前进边缘飞溅的小粒子。 * 利用 Sparse Solver 创建体积化的雪粉效果。 * 通过纹理平面生成 3D 几何体，用于树木碰撞。 * 将体积化雪粉作为触发器，模拟出风力效果。 4. **渲染与合成：** * 演示 Redshift 渲染器的使用，并提供 Mantra 渲染器的替代方案。 * 讲解完成一套完整特效镜头所需的各种渲染。 * 使用 Natron（或 Nuke）进行后期合成，组装最终的特效镜头。 **教学方法：** * 将复杂的特效分解为多个小型模拟，循序渐进地构建。 **课程版本：** * 使用 Houdini 18.5.499。 * 兼容支持 Sparse Solving 的 Houdini 版本。 * 早期版本用户可使用 Dense Solver 进行雪粉模拟。 **建议：** * 观看介绍视频和免费试看视频，了解课程风格。 * 如有疑问，欢迎随时提问。
Hello Houdini Artists.! This course will show you all the steps involved in setting up an Avalanche FX rig.There are over 5 hours of lecture videos going over the process of creating this setup.You should have working knowledge of Houdini before enrolling in this course. If you have done my previous Houdini course "Master Houdini FX", you will have all the Houdini basics needed to be able to follow this course with ease.This course is "Fast paced", which means I will not be explaining every function of every node I use on screen. I will explain what is necessary, but basic nodes will not be explained in detail, this is to try keeping this total course time to a minimum and to not bore those that have a working knowledge of Houdini's core functions and nodes.All lectures will have Houdini hip files for you to download and any other necessary assets. There are two sets of files for students to download. Files for those rendering in Redshift, and files for those rendering in default Mantra. The rendered output of the Redshift render will not be exact to the Mantra output since they are different engines using different shaders and lighting, but they will be pretty close.If you have any questions, please feel free to ask. I encourage you to watch the intro video and watch some of the "free" videos so you can get a sense of what the course is like.This course will be using Houdini 18.5.499. If you have any version of Houdini that has sparse solving, then you should have no problems following along with the lecture videos. You can still do the entire course if using an earlier version(as long as it has grains), you would just have to use the dense solver for our snow powder sim.Here is the basic breakdown of the course:We will start by examining the still image I used to create a "2.5D" scene for us to create our Avalanche Effect in.We will discuss what parallax is and why it is important and how to "fake it" to create what looks like moving footage from any still image.We will show how to use grains to create a large volume of particles that stick together like a body of snow moving down a mountain side.We will see how to do many tricks to add additional FX elements like small particles flying up from the leading edge and use sparse solving to create volumetric snow powder.We will see how to create 3D geometry from a textured plane to generate Tree collision geometry.I will show you a trick to get the volumetric snow powder to trigger emission of particles to act as a wind force.We will then go into rendering and I will show how to create all the renders necessary for a full comp.We will be using Redshift in the course and on screen, however you can use Mantra if you do not have the Redshift Plugin. There will be scene files for you to download that are setup for Redshift shaders, and another set of scene files that are for rendering with Mantra shaders.Once all the renders are done, we will assemble a full comp using Natron, or you can use Nuke if you have access to it. I will be presenting a very straight forward and approach to creating an FX shot like this. We will break it down into smaller sims and go through it step by step progressively building new sims from previous sims until we are done with the shot. If you have been using Houdini for a little while, you should have no problems following this course. If you need a refresher or are just starting to use Houdini, I recommend doing my first Houdini course "Master Houdini FX" as a primer to this course.
