个人游戏《Hooo的传奇》开发日志：使用Auto IK Rigger+Bone Layer Manager+Orient bone shapes优化我的蒙皮绑定工作流

标题中的三个插件：

• 《Auto IK Rigger：一个可以真·一键绑定的轻量级Blender插件》（该插件为付费插件，不提供下载，见谅）
• Bone Layer Manager 0.84 的下载
• 《Blender图解教程：使用Orient bone shapes插件轻松解决设置骨骼自定义形状（Bone Custom Shapes）时的各种痛点（附下载）》

优化一下工作流

最近在开发游戏的时候又遇到一个比较头疼的问题：角色设计。虽然前几天设计了几个版本，但是由于种种原因还要重新设计，而且形体的变化也会比较大，未来这种情况也会时有发生（关于角色设计问题的总结将另起博文详述）。所以产生一个问题：动不动就要重新蒙皮绑定，或者为骨架添加一些新的结构。以前用Rigify总的来说是不错的，但Rigify的绑定层次比较深，如果想快速地添加一些自定义结构，都需要从Metarig做起，生成完Rig还要重新修改脚本来编辑骨骼组，还是很繁琐。

想来想去，针对自身的情况，老王打算尝试一下新的工具（也就是题目中的三个插件）和工作流（先用临时模型动画，角色慢慢设计）。 Auto IK Rigger的优点：

• 简单：易于二次开发。
• 先蒙皮再绑定，这样就可以借助Mixamo的实现蒙皮。

其它两个插件是辅助插件，用于管理骨骼组和设置自定义形状。

一些优化设置

• Mixamo骨骼重命名：使用Ctrl + F2批量重命名，去掉前缀mixamorig:并将"Left/Right"替换为L./R.我的bone_names.json文件见下面
• 在Auto IK Rigger可以把不需要形变的骨骼都取消deform勾选，默认都是勾选的。可以用Bone Layer Manager的Deform Bones Only过滤显示并检查一下。
• 可以把所有骨骼不需要的变换轨道锁定。
