Trailer – Grooming Barry Bacon by Gabriela Salmeron

Barry Bacon is our character, which we will groom and render in Houdini. This is a short course, made up of two parts. Part 1 covers how to prepare your scene, comb guides and add parting lines. Part 2 goes over how to generate hair, clump them, add variations and render it in Mantra. There is also a separate introduction series, for beginners, to go over basics on grooming in Houdini. All three parts are by Senior Grooming Artist Gabriela Salmeron.

Chapter 1 – Introduction to Scene Prepare

We begin by looking at how to prepare our scene for grooming. We will have a general overview on scene UI layout, some optimization tips, prepping our geometry so as to reduce issues later on and how to work when grooming with reference.

Chapter 2 – VDBs

We will use the Guidegroom, which will allow us to have guide creation and guide combing. We will look at what settings to use for better performance. Additionally we will optimize our geometry for conversion to VDB.

Chapter 3 – Alternative GuideGroom

Now we are ready to start combing guides on Barry Bacon. I will show you how I like to have my guides displayed, so I know what are the guides that are masked and what are not. I can also adjust the width of my guides so that it is more visible and easier to work with in the viewport. This custom guidegroom is available for download in the scene file below.

现在，我们准备开始在Barry Bacon上梳理指南。我将向您展示我希望如何显示我的指南，因此我知道哪些是隐藏的指南，哪些不是。我还可以调整辅助线的宽度，以使其在视口中更可见且更易于使用。可在以下场景文件中下载此自定义指南室。

Chapter 4 – Flow

Before starting on grooms, it is important to analyze your reference material and break down what you will be grooming. Barry Bacon has many different fur characteristics, so we draw out what those areas are.

在开始进行美容之前，重要的是分析您的参考资料并分解您要进行的美容。巴里·培根（Barry Bacon）具有许多不同的皮毛特征，因此我们要找出这些区域是什么。

Chapter 5 – Flow Sketch

We work side by side now with the reference sketch we just made, and we do that now in 3D on our Barry Bacon geometry. We will use the stroke node to draw out where the different fur types will be.

现在，我们与刚刚制作的参考草图并排工作，现在我们在Barry Bacon几何图形中以3D进行处理。我们将使用笔触节点绘制不同毛发类型的位置。

Chapter 6 – Combing Face

Using hotkeys that has been covered in a previous video (in the introduction part3), I start planting and combing each guide to match the hair profile as seen in our reference image. This is a manual process, but it will give a much more finer control. We also use mirror to place guides on the other side of the face, which helps us to place guides throughout the face. There is also a tip, where I use a visualizer to immediately read the length of my guides. This is very useful, as your number of guides will increase and you can evaluate and make an more accurate groom this way.

谷歌翻译：
使用上一个视频（在第3部分的介绍中）介绍的热键，我开始植入和梳理每个指南以匹配头发轮廓，如我们的参考图像所示。这是一个手动过程，但是它将提供更好的控制。我们还使用镜子将引导线放置在脸部的另一侧，这有助于我们将引导线放置在整个脸部。还有一个技巧，在这里我使用可视化工具立即阅读指南的长度。这非常有用，因为指南的数量将增加，并且您可以通过这种方式进行评估并做出更准确的修饰。

Chapter 7 – Combing Long Hair

Now we will do the guides for the forehead, as well as the ears, in separate guidegroom nodes. I use this method to keep my groom organized, so I can easily go back and make adjustments when needed.

现在，我们将在单独的引导节点中为额头和耳朵提供引导。我使用这种方法来使新郎保持井井有条，因此我可以轻松地返回并在需要时进行调整。

Chapter 8 – Breaking Symmetry

Next we will break the symmetry. This is very important, to achieve a natural look. Otherwise you will end up with a very visible seam in the middle. Since we already have most of our work done, we are just removing some guides, and placing new ones to largely overlap, to cover up any visible lines. We will also use parting lines to help as well.

谷歌翻译：
接下来，我们将打破对称性。这对于获得自然外观非常重要。否则，您将在中间出现一个非常明显的接缝。由于我们已经完成了大部分工作，因此我们只是删除了一些指南，而将新的指南放在很大程度上重叠的地方，以掩盖任何可见的线条。我们还将使用分型线来提供帮助。

Chapter 9 – Combing Guide Process

Now we will use a guideprocess to adjust our guides. Guideprocess is essentially modifiers for guides, so they can affect the result of the guides, and this helps us to save time. In this case, we are adjusting the forehead patch because our initial guides no longer fit with the rest of the guides on the face and ears.

谷歌翻译：
现在，我们将使用guideprocess来调整我们的指南。 Guideprocess本质上是指南的修饰符，因此它们可以影响指南的结果，这有助于我们节省时间。在这种情况下，我们正在调整前额贴片，因为我们的初始指南不再适合脸部和耳朵上的其他指南。

Chapter 10 – Hair Generation

We will begin by painting attributes in order to generate our hair; we will paint density maps. We will use a custom material to better see on the skin, where we will paint the attributes.

Chapter 14 – Clumping Structure

We will see how to refine Barry Bacon by splitting the groom across his face, separate from the top of the head and ears area. We just need to pay attention to not make any obvious seams, to ensure a natural look. We will do so by using masks to help the different areas blend together.

我们将看到如何通过将新郎分开到头部和耳朵上方的顶部来分开新郎，以完善Barry Bacon。我们只需要注意不要做任何明显的接缝，以确保外观自然。我们将使用遮罩来帮助将不同区域融合在一起。

Chapter 16 – Ears and Top Head

Now we have the groom on Barry Bacon’s ears and top of his head, but without shading at this point. Let’s have a look at the setups of both – they are rather similar. There are variations in width, parting lines, fly-away hairs, density, clumping, length and a bit of bend.

现在，新郎在巴里·培根的耳朵和头顶上，但此时没有遮挡。让我们看一下两者的设置-它们非常相似。宽度，分型线，飞散的头发，密度，成簇，长度和弯曲程度都有所不同。

Chapter 17 – Shading

Let’s see how we set it up with the hair shader for Barry Bacon. There are separate hair materials per areas of his face. We will use attributes to bind and control specific things like root colour, specularity, saturation, tip colour, and more.
