Sidefx Solaris Houdini _ Part 1 – USD and Solaris introduction

This is the first part of a tutorial series about Universal Scene Description and Houdini Solaris.

Trying here first to introduce some of the USD lingo and see how Houdini/Solaris is using its nodal approach to wrap the USD concepts arounds a category of nodes called “lops”.

I usually prefer going through practical exercises than this sort of theoretical demonstration, but USD isn’t the most straightforward thing to pickup and we we need to build up the knowledge from the ground up ! So let’s get started with that =D

这是有关通用场景描述和 Houdini Solaris 的教程系列的第一部分。

首先在这里尝试介绍一些美元术语，并了解 Houdini/Solaris 如何使用其节点方法将美元概念包装在称为“lops”的节点类别周围。

我通常更喜欢通过实践练习而不是这种理论演示，但美元并不是最直接的东西，我们需要从头开始积累知识！所以让我们开始吧 u003dD

Sidefx Solaris Houdini _ Part 2.5 – MORE Megascan Assets to USD

In part 2 we saw how we could turn some megascan into USD for our asset context gallery… but clearly quixel Bridge got more challenges reserved for us if we want to get ready to layout our different elements for our environment.

Also SideFX is introducting H19.5, a lot more of their tools rely on the asset gallery so it’s important you are able to store your models as USD into the asset gallery. Check out sidefx page for more info :
https://www.sidefx.com/community/houdini-195-sneak-peek/

Working out here a setup that you can reuse as much as you want to make your life much easier.

Clarifying also some more things between materialX and how it differs compare to “USD Material Preview”.

One hour of free content in the first part if you wish to give it a try, also providing the tool to convert principleShaders to MtlX for free in part1-Python Fundamentals :
https://adrienlambert.gumroad.com/l/pythfx

00:00 – Introduction
01:02 – USD Material Preview
05:32 – Mtlx Displace Clarification
06:46 – Megascan Leaves USD
17:37 – Megascan Stones, Debris, twigs…
24:00 – Variants to Asset Galery
25:54 – Get ready for part3

此外，SideFX 正在引入 H19.5，他们的更多工具依赖于资产库，因此能够将模型作为美元存储到资产库中非常重要。查看 sidefx 页面了解更多信息：

在这里制定一个您可以尽可能多地重复使用的设置，让您的生活更轻松。

还澄清了 materialX 之间的更多内容以及与“USD Material Preview”相比的不同之处。

Sidefx Solaris Houdini _ Part 3 – Layout and Scattering USD assets

Showing here all the ways to bring USD into Stage, different methods to layout scatter and drop them !

Working here in a somewhat quick and dirty way to show the tools, but we’ll have to see at one point how we can make hierarchy nice and clean and make sure we cover organization of USD layers so we can share out scene with other software like Omniverse, Unreal Engine etc…

00:00 – introduction
01:12 – USD import methods
06:12 – Layout lop
09:21 – Paint Tool frustrations…
12:30 – Terrain Creation
13:43 – Stack Brush
14:20 – Drop lop
18:48 – Starting layout
19:40 – Instancer and Scattering
30:27 – Index Attribute
32:05 – Setting up Camera
33:00 – Scattering Grass
36:29 – Adding Hero elements
37:14 – Scene crash… Conclusion

I noticed Houdini v19.5 tends to crash a lot on my side with the “layout” lop… don’t do the same mistakes… save your scene ! T__T

在这里以一种有点快速和肮脏的方式来展示工具，但我们必须在某一时刻看到我们如何使层次结构变得干净整洁，并确保我们涵盖了 USD 层的组织，以便我们可以与其他软件共享场景比如Omniverse、虚幻引擎等……

Sidefx Solaris Houdini _ Part 3.5 – Editing Layout LOP brushes

This additional part is very much a hack on how to edit the brushes of Layout LOP to bend them to your will…
It’s a much more technical video than usual but taking the time to explain how Orient attributes and Quaternions works to control the rotation of our assets.
Showing here two ways to manipulate these attributes. First by using AttributeVOP (visual coding similar to UnrealEngine) or VEX scripting (Based on C language)

00:00 – Introduction
00:30 – What we want to fix
01:35 – Making brushes editable
03:51 – Fixing Scale
06:06 – Checking Orientation based on Normal
08:37 – Breakdown of align_to_normal
09:31 – What is a Quaternion ??
10:40 – Fix paintbrush with AttributeVop
22:23 – Fix paintbrush with VEX
28:25 – Outro

这个额外的部分是关于如何编辑 Layout LOP 的画笔以将它们弯曲到你的意愿的一个非常黑客……
这是一个比平时更具技术性的视频，但花时间解释了东方属性和四元数如何控制我们资产的旋转。
这里展示了两种操作这些属性的方法。首先使用 AttributeVOP（类似于 UnrealEngine 的可视化编码）或 VEX 脚本（基于 C 语言）

00:00 – 介绍
00:30 – 我们想要解决的问题
01:35 – 使画笔可编辑
03:51 – 固定规模
