Maya动画入门：一步步教你制作狗狗跑步动画！

516e775793fed96794ca2e264c849c81_wps%e5%9b%be%e7%89%87_8

3D动画：狗狗跑步参考图

视频中所用的狗狗绑定模型来源：3D Pincher Dog – TurboSquid 1714212

免费版权狗狗绑定模型推荐：dog rig in maya free 3D model rigged | CGTrader

从第1帧开始，制作第1个关键pose，狗的前后脚单脚踩地，调整重心和头部角度。

在第3帧，制作第2个关键pose，前双脚踩地，后双脚离地，调整重心和头部角度。

在第5帧，制作第3个关键pose，一只前脚踩地，后脚离地，调整重心和头部角度。

在第7帧，制作第4个关键pose，一只后脚踩地，前脚离地，调整重心和头部角度。

在第9帧，制作第5个关键pose，后双脚踩地，前双脚离地，调整重心和头部角度。

第11帧回到第1帧的pose，复制第1帧的pose到第11帧，形成循环。

Maya 教学：Maya启动加载速度提升一倍

maya启动慢，进入软件界面卡顿解决办法：
在主菜单栏中，选择“窗口 → 设置/首选项 →插件管理器”(Windows → Settings/Preferences → Plug-in Manager)，取消勾选bif四项，mash，xgen，mota，然后重启maya即可。

bif，
bifmeshio.mll
允许以逐帧 .bif 文件格式缓存多边形网格。请参见使用 BIF 格式缓存网格。

bifrostGraph.mll
激活适用于 Maya 的 Bifrost Extension，这是一个用于实现程序效果的基于节点的框架。

bifrostshellnode.mll、bifrostvisplugin.mll
激活 Bifröst 流体模拟框架。

mash，
MASH.mll 做mash动画的插件

xgen，
xgenToolkit.mll XGen 几何体实例化器做毛发的插件

mtoa，
Mtoa.mll 阿诺德渲染器插件

Maya Advanced Skeleton 5 人物头发绑定

本次视频介绍人物头发的绑定。

1.打开骨骼透视，显示关节
2.创建并对齐骨骼
3.创建控制器，吸附到骨骼中心
4.把骨骼和控制器分别P给头部骨骼和控制
5.用控制器父对象约束对应的骨骼
6.选择所有骨骼加选头发，添加影响
7.绘制权重，解锁骨骼权重锁定
8.通过旋转角度来辅助绘制权重
9.测试最终绑定效果
10.通过高级骨骼绑定插件发布最终文件
