你会学到什么

本课程将向您展示从摄影图像炸毁真实世界建筑物的所有步骤。
我将向您展示如何分解建筑物的几何形状并创建自定义“块”以用作 rbd 对象。
我们将看到如何创建代表混凝土、玻璃和百叶窗的不同类型的 RBD 对象。
我们将使用 Vellum sims 来创建因爆炸而变形的弯曲几何体。
我们将使用更现代的稀疏求解方法来创建一个爆炸火球。
我们将创建创建最终合成所需的所有渲染。
我将向您展示如何使用爆炸作为光源来照亮场景。
我们将使用 Natron 创建最终组合。

要求

强烈建议在开始本课程之前了解 Houdini 的工作知识。
最近发布的带有稀疏求解工具的 Houdini(18+)。
一台有足够能力运行 Houdini 和用于高清流媒体的良好互联网连接的计算机。
本课程将在整个视频中在基于 Windows 10 的系统上使用 Houdini 18.5.499。

描述

你好潜在的学生。！本课程将涵盖您需要了解的所有内容，以便从真实照片中摧毁和炸毁建筑物。

有超过 10.5 小时的讲座视频讲述了摧毁建筑物的过程。

在注册本课程之前，您应该具备 Houdini 的工作知识。如果您已经完成了我之前的 Houdini 课程“Master Houdini FX”，那么您在学习本课程时不会有任何问题，因为我建立在第一门课程中介绍的许多初始绑定创建原则的基础上。

这是一门“快节奏”课程，这意味着我不会解释我使用的每个节点的每个功能。我会在必要的地方进行解释，但不会详细解释基本节点，这是为了尽量减少总课程时间，以及在注册这个中级课程之前你应该具备基本的 Houdini 知识的另一个原因。

所有讲座都将有 Houdini hip 文件供您下载和任何其他必要的资产。如果您有任何问题，请随时提问。我鼓励您观看介绍视频并观看一些“免费”视频，以便您了解课程的内容。

课程的基本分解是这样的

我们将从概述我如何以及为什么选择我所做的建筑物作为我们的主题开始。

我将包含模型文件并简要介绍我为建筑物建模所做的工作，但不会逐步显示创建过程。布尔建模大约需要 4.5 小时才能完成，如果让您观看模型过程，那将是不必要的无聊。！

然后，我们将开始有选择地逐段破坏建筑模型，直到我们所有的几何形状都被破坏。

然后我们开始做 RBD 模拟，甚至在混合中加入一点牛皮纸，以使我们的模拟更有趣。

一旦我们完成了 RBD 和牛皮纸，我们就可以使用更现代的“稀疏”模拟工具来模拟我们的火球爆炸。

然后，我们将创建一个 embers 通行证，为我们的模拟市民提供一些额外的东西。

我们将创建和分配我们需要的任何和所有着色器。

然后我们将进入渲染，我将展示如何创建完整合成所需的所有渲染。

本课程将使用 Mantra 作为我们的渲染引擎，以保持“现成的 Houdini”，而不是依赖插件。

完成所有渲染后，我们将组装一个完整的合成，包括相机抖动，以增加最终结果的真实感。

本课程将教您所有您需要知道的知识，以便您能够外出拍摄您自己的建筑并创建您想要的所有自定义破坏。使用随附的图像和建筑物几何图形完成本课程后，您将准备好在您自己的城镇中找到您自己的建筑物，以便在您选择的建筑物上拍摄和重新创建此设置。我将介绍一种非常直接且“简单”的方法来创建这样的 FX 镜头。

如果您使用 Houdini 已经有一段时间了，那么您在学习本课程时应该没有问题。如果您需要复习或刚开始使用 Houdini，我建议您学习我的第一门 Houdini 课程“Master Houdini FX”作为本课程的入门。

本课程适用于
任何有兴趣从拥有 20 多年后期制作经验的 FX 艺术家那里了解炸毁和摧毁 Houdini 内任何类型建筑物的步骤的人。
有抱负的 FX 艺术家和工作专业人士希望学习新技能或了解创建建筑破坏 FX 的一种方法。

What you’ll learn

This course will show you all the steps involved in blowing up a real world building from a photographic image.
I will show you how to fracture the building geometry and create custom “chunks” to use as rbd objects.
We will see how to create different types of RBD objects representing concrete, glass, and window blinds.
We will use Vellum sims to create bending geometry that deforms from the explosion.
We will use the more modern sparse solving method to create an exploding fireball.
We will create all renders necessary to create a final comp.
I will show you how to use the explosion as a light source to illuminate the scene.
We will create a final comp using Natron.

Requirements

A working knowledge of Houdini is strongly recommended before starting this course.
A recent release of Houdini(18+) with Sparse solving tools.
A computer with enough power to run Houdini and a decent internet connection for HD streaming.
This course will be using Houdini 18.5.499 on a windows 10 based system throughout the videos.

Description

Hello potential students.! This course is going to cover everything you need to know in order to destroy and blow up a building from a real photograph.

There are over 10.5 hours of lecture videos going over the process of destroying a building.

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 no problem following this course since I build on a lot of the initial principles of rig creation that were presented in the first course.

This is a “Fast paced” course, meaning I will not be explaining every function of every node I use. I will explain where necessary, but basic nodes will not be explained in detail, this is to try keeping this total course time to a minimum, and another reason you should have basic Houdini knowledge prior to enrolling into this mid level course.

All lectures will have Houdini hip files for you to download and any other necessary assets. 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.

The basic breakdown of the course goes like this

We will start with an overview of how and why I chose the building I did to use as our subject.

I will include the model file and briefly go over what I did to model the building, but will not be showing the creation process step by step. It took around 4.5 hours of Boolean modelling to finish and would be unnecessarily boring to make you watch the model process.!

We will then start selectively fracturing the building model section by section until we have all geometry fractured.

We then start doing RBD sims and even throw a little vellum into the mix to make our sim more interesting.

Once we have our RBD’s and vellum finished, we go into simulating our fireball explosion using the more modern “Sparse” simulation tools.

We will then create an embers pass to give our sim a little something extra.

We will be creating and assigning any and all shaders that are needed as we go.

We will then go into rendering and I will show how to create all the renders necessary for a full comp.

This course will be using Mantra as our render engine to keep things “off the shelf Houdini” and not rely on plugins.

Once all the renders are done, we will assemble a full comp including camera shake to add some more realism to the end result.

This course will teach you everything you need to know to be able to go out and photograph your own building and create all the custom destruction you wish. Once you finish this course using the included image and building geometry, you will be ready to find your own building in your own town to photograph and recreate this setup on a building of your choice. I will be presenting a very straight forward and “easy” method to creating an FX shot like this.

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.

Who this course is for
Anyone that is interested in seeing the steps involved to blow up and destroy any type of building inside Houdini from an FX artist with 20+ years experience in post production.
Aspiring FX artists and working professionals looking to learn new skills or see one method in creating building destruction FX.
