在本分步视频课程中,你将学习如何绑定骨架 3D 模型。我们将使用 Blender(一款免费的开源 3D 内容创作套件)以及免费的自动绑定系统 Rigify。
课程的最终结果
课程结束后,你将拥有一个完整绑定的骨架模型,并使用动作捕捉和重定向技术进行动画制作。你甚至可以根据需要将其导出到游戏引擎。
为什么装配骨架如此困难
您在大多数教程中学习的索具和重量绘画技术适用于具有皮肤和衣服的“标准”角色。
Rigify 提供了令人惊叹的开箱即用功能,例如扭曲骨骼(由弯曲骨骼辅助)。
自动权重和高级附加组件(如 Voxel Heat Skinning)可帮助我们快速为连接的网格添加蒙皮。
然而,当应用于骨架时,许多这些技术不仅无用……而且它们造成的问题比解决的问题还多。
本课程如何帮助您
在本课程中,您将学习:
• 如何调整默认的 Rigify 设置并使 Rigify 适合装配骨架。
掌握 Rigify 装备类型设置将帮助你装备多才多艺的角色
• 特殊的权重绘制技术,可快速高效地将网格骨骼与绑定骨骼绑定。骨架中的许多骨骼需要始终保持坚固(例如腿骨、上臂、颅骨等),而其他骨骼则需要弯曲或扭转(例如小臂骨骼、脊柱、胸腔等)。
权重绘制占绑定的50%。我可没开玩笑!
• 自定义绑定技巧。您可以使用简单的绑定构建块来绑定几乎整个骨架。但为了实现某些高级效果,我们需要从头开始创建自定义绑定。我将向您展示如何创建自定义绑定,以及如何将它们与其他绑定部件无缝集成。
简单还是高级:由您选择
只要有可能,我都会尝试让您在简单和高级技术之间做出选择。
• “简单”的技术将帮助您以最小的努力取得良好的结果。
• 高级技巧将向您展示如何通过一些额外的努力获得更好的结果
并非初学者课程
这是一个循序渐进的教程,但需要具备 Blender 的基础知识。我还建议您对 Rigify 有基本的了解。如果您是 Rigify 新手,我将提供必要的资源,帮助您快速掌握 Rigify。不过,在深入学习骨架课程之前,您可能需要进行一些额外的学习。
课程结构
第一部分:简介和资源
只是打个招呼,并向您介绍课程、资源和联系我的方式。
第 2 部分:网格准备
“如果你没有计划,你就注定会失败”。我们会准备模型并组织场景。这将使我们的绑定工作更加轻松。
第 3 部分:Metarig
我们会快速将一个标准的元绑定与骨架对齐。之后还需要进行大量的定制,但这只是一个开始。
接下来的 5 个部分将分别重点介绍骨架特定部分的装配和重量绘制。
第四部分:腿、脚、Teos
第五部分:手臂、手、手指
第六部分:躯干(骨盆、脊柱、胸腔)
第七部分:锁骨和肩胛骨
第 8 部分:头部、颈部、下颌
这样,骨架装配就完成了,但我还添加了您可能会喜欢的附加章节。
第 9 部分:自定义装备脚本
我们将使用 Blender 3.0+版本中 Rigify 的新功能,该功能允许我们在生成绑定后立即运行脚本。这样,我们就可以进一步自定义绑定,实现其他方式无法实现的功能。
第 10 部分:清理
索具的一个重要但经常被忽视的部分:清理场景,并仔细检查一切是否正常!
第 11 部分:道具
我们将为骨架提供其可以容纳的道具(一面盾牌和一把剑,多么新颖!)
第 12 部分:重新定位
我将向您展示使用 Rokoko 插件(免费)进行重新定位的工作流程,以便正确地将动作捕捉数据传输到 Rigify 装备(包括 IK 重新定位)
第 13 部分:游戏引擎导出(即将推出!)
开箱即用的 Rigify 绑定并非用于导出到游戏引擎。但我会向您展示一个可靠的工作流程,帮助您将干净的游戏绑定导出到 Unreal 或 Unity(或任何其他引擎)。
第14部分:结论
对于你们当中那些迷信的人来说,如果课程有 13 个章节,他们就会感到不安。
FAQ
是否包含骨架 3D 模型?
是的,您可以使用我在视频中使用的相同 3D 模型。如果您愿意,也可以使用您自己的模型。
我需要哪个版本的 Blender?
我在视频中使用的版本是 3.1,建议您使用相同或更高版本。不过,您也可以使用旧版本,例如 2.93 甚至 2.83 LTS。在视频中,我会尽量考虑到大家可能使用的是不同版本的 Blender,并尝试提供一些建议。
Gumroad – Rig a Skeleton with Blender and Rigify
Info:
In this step-by-step video course, you’ll learn how to rig a Skeleton 3d model. We’ll be using Blender – the free and open-source 3d content creation suite – and the free auto-rigging system Rigify.
THE FINAL RESULT FROM THE COURSE
By the end of the course, you’ll have a fully rigged skeleton model, animated using mocap and retargeting. You can even get it ready for export to a game engine, should you wish to.
WHY RIGGING A SKELETON IS DIFFICULT
The rigging and weight painting techniques you learn in most tutorials are meant for “standard” characters with skin and clothing.
Rigify offers amazing features such as twist bones (aided by bendy bones) out of the box.
Automatic Weights and advanced add-ons such as Voxel Heat Skinning help us quickly skin connected meshes.
However, when applied to a Skeleton, many of these techniques are not just useless …but they cause more problems than they solve.
HOW THIS COURSE CAN HELP YOU
In the course, you’ll learn:
• How to tweak the default Rigify settings and make Rigify suitable for rigging a Skeleton.
Mastering the Rigify rig type settings will help you rig versatile characters
• Special weight paint techniques to quickly and efficiently bind the mesh bones to the rig bones. Many bones in the skeleton need to stay solid at all times (leg bones, upper arm, cranium, etc.) while others need to bend or twist (lower arm bones, spine, ribcage, etc).
Weight Painting is 50% of Rigging. I am not even joking!
• Custom rigging techniques. You can rig almost the entire skeleton with simple Rigify building blocks. But to achieve certain advanced effects we’ll need to create custom rigs from scratch. I will show you how to create those and also, how to seamlessly integrate them with the other Rigify parts.
SIMPLE OR ADVANCED: THE CHOICE IS YOURS
Whenever possible, I tried to give you a choice between simple and advanced techniques.
• The “simple” techniques will help you achieve good results with minimal effort.
• The advanced techniques will show you how to get even better results with some additional effort
NOT EXACTLY A BEGINNER’S COURSE
This is a step-by-step tutorial but a basic knowledge of Blender is required. I’d also recommend a basic understanding of Rigify. If you are new to Rigify I am going to provide the necessary resources to get you up to speed with Rigify. Just understand that you may need to do some additional learning before diving into the Skeleton lessons.
COURSE STRUCTURE
Part 1: Intro & Resources
Just saying “hi”, and introducing you to the course, resources, and ways to contact me.
Part 2: Mesh Prep
“If you fail to plan, you plan to fail”. We’ll prepare the model and organize the scene. This will make our rigging work much easier
Part 3: Metarig
We’ll quickly align a standard metarig to the skeleton. It will need a lot of customization down the line but it’s a start.
The next 5 parts will each focus on the rigging and weight painting of a specific section of the skeleton.
Part 4: Legs, Feet, Teos
Part 5: Arms, Hands, Fingers
Part 6: Torso (Pelvis, Spine, Ribcage)
Part 7: Clavicle and Scapula
Part 8: Head, Neck, Jaw
With that, the skeleton rigging is done but I have included additional chapters that you may enjoy.
Part 9: Custom Rigify Script
We’ll be using a new feature of Rigify (Blender 3.0+) which allows us to run a script as soon as we generate the rig. This way we can customize the rig even further and in ways that are not possible otherwise.
Part 10: CleanUp
An important but often neglected part of rigging: clean up your scene, and double-check that everything works!
Part 11: Props
We’ll give the skeleton Props that it can hold (a shield and a sword, how original!)
Part 12: Retargeting
I’ll show you my workflow for retargeting using the Rokoko addon (free) to correctly transfer mocap data to the Rigify rig (including IK retargeting)
Part 13: Game Engines export (Coming soon!)
Out of the box, the Rigify rig is not meant for export to game engines. But I’ll show you a solid workflow to export a clean game rig to Unreal or Unity (or any other engine).
Part 14: Conclusion
For the superstitious among you who would feel uneasy if the course had 13 chapters.
FAQ
Is the Skeleton 3d model included?
Yes, you’ll have access to the same 3d model that I am using in the videos. You can also use your own model if you prefer.
What version of Blender will I need?
The version I use in the video is 3.1 and I recommend that you use the same or later. However, you will be able to follow along with older versions such as 2.93 or even 2.83 LTS. In the videos, I try to anticipate that people may be using different versions of Blender and try to suggest what to do.
Are the skeleton and rig anatomically correct?
Not in a scientific sense. We will be rigging a skeleton model for animation, games, etc. While the result is fairly realistic, it is not a simulation of real skeletal anatomy.
The tone of the course is casual and you will rarely hear me use the Latin name of bones etc. (because I don’t know them … Wait, did I say that out loud? )
Can I rig a cartoony skeleton with the same techniques?
I think so but I can’t guarantee it. If it’s just the looks and proportions that are cartoony, then it should be fine. But if you need, say, extreme limb bending, you may need to improvise and change the setup somewhat.
