要求
具备 Houdini 界面的基本知识。
基本了解Houdini通道（参数）参考。
基本了解 Houdini 中的属性是什么。
对 Houdini For Each Loops 的基本了解（没什么疯狂的）。
创建了至少一些基本的 Houdini 模型（程序或传统方式）。选修的。
具有虚幻引擎 5 的基础知识。
安装了虚幻引擎 5 和 Houdini 引擎插件。

描述
非常感谢您的浏览。为了调整您的期望，我不会共享源文件（HDA 和 HIP）。这样做是有意为之，以便您可以练习并更好地体验 Houdini 的使用。我个人的使命是尽我所能帮助人们真正了解 Houdini 并使用它的力量。没有练习就没有捷径可以理解某些东西。课程有完整的叙述。唯一的最后一个视频是延时摄影。Houdini 注重效率。您创建一个工具一次，在多个项目中使用它，并对其进行完善以适应不同的任务。尽管最终的模型看起来很简单，但本课程涵盖了一些常见的程序建模方法，例如随机化、foreach循环以及制作时面临的其他问题程序模型。了解类似的技术将有助于接近您需要创建的任何其他模型。本课程从初级初级开始，“攀登”到中高级。本课程分为多个小部分，因此不会让人感到不知所措。本课程的目的是：- 提供可能在现实场景中使用的示例，而不是创建抽象模型。- 增加您对 Houdini 的理解以及确定性一切正常。- 加深您对虚幻引擎 5 的 Houdini 引擎用例的理解。这是一个基于项目的课程，我们将创建 4 个 Houdini 数字资产 (HDA)，您可以在不同的项目中重复使用它们：1。铅笔 HDA.2。案例HDA.3。盒子 + 铅笔 HDA（盒子内散落铅笔）.4。用铅笔将箱子分散在 HDA 区域范围内。所有 HDA 都期望“Case HDA”将支持刚体模拟，换句话说，铅笔将与碰撞几何体相互作用。我为自己的环境项目创建了这个模型，因此决定分享我的创建方法。本课程分为 3 个部分：1. 铅笔 HDA 创建 + RBD.2。铅笔盒HDA+铅笔盒内的分散铅笔HDA和随机铅笔+RBD.3。分散铅笔盒，随机分配铅笔盒/铅笔 RBD。一些讲座包含附加描述以及我错过解释的信息。例如某些节点的目的是什么。随机化案例/铅笔 RBD。一些讲座包含附加描述以及我错过解释的信息。例如某些节点的目的是什么。随机化案例/铅笔 RBD。一些讲座包含附加描述以及我错过解释的信息。例如某些节点的目的是什么。

Description
Grateful for you taking a look. To adjust your expectations, I won’t be sharing source files (HDA and HIP). This is done on purpose so you can practice and get a better feel using Houdini. My personal mission is to do my best to help people actually get a feel of Houdini and use its power. There’s no shortcut to understand something without practice.The course is fully narrated. The only very last video is a timelapse. Houdini is all about efficiency. You create a tool once, use it on multiple projects, and polish it to suit different tasks.Even though the final models look simple, this course covers some common procedural modeling approaches such as randomization, for each loops, and other faced things when making procedural models. Understanding similar techniques will help to approach any other model that you need to create.This course starts from the upper beginner level and “climbs” to the intermediate-advanced level. The course is split into small parts so it doesn’t feel overwhelming.This course is aimed to:- provide examples that might be used in a real-world scenario rather than creating an abstract model.- increase your understanding of Houdini and how certain things work.- increase your understanding of uses cases of Houdini Engine for Unreal Engine 5.This is a project-based course where we’ll create 4 Houdini Digital Assets (HDA) that you can reuse in different projects:1. Pencil HDA.2. Case HDA.3. Case + Pencil HDA (scatter pencils within the case).4. Scatter cases with pencils within area bounds HDA. All HDAs expect “Case HDA” will have support for Rigid Body Simulation, in other words, pencils will interact with collision geometry. I’ve created this model for my own environment project and thus decided to share my approach to creating it.The course has 3 sections:1. Pencil HDA creation + RBD.2. Pencil case HDA + scattering pencil HDA within that case and randomizing pencils + RBD.3. Scatter pencil cases, randomizing cases/pencils RBD.Some of the lectures contain additional description with the information I missed explaining. Such as what’s the purpose of certain node(s).
