在Blender使用Rigify创建循环步行动画 Create an Animation Walk Cycle in Blender using Rigify

Step 27

Now the cycle will end with the pose the same as the first pose, so we will copy that from frame one and then paste as is on frame 41. So go to frame one and select all the bones and copy the pose and paste it on frame 41. OR you can select the 1st keyframe in the dopesheet summery, and the press Shift+D to make a duplicate. Go to frame 41 and Left-click to confirm its position.
现在循环结束姿势和第一帧一样，所以我们将从第一帧复制并粘贴到41帧。所以到第一帧选择所有的骨骼复制姿势并粘贴到41帧。或者您也可以选择在dopesheet第一关键帧，然后按Shift键+ D进行复制。转至帧41和左键单击以确认其位置。



Press Play and preview the complete walk cycle.
按播放和预览完整的步行周期。

Step 28

To preview the animation in a loop, Type '40' in the End frame limit box. We are having the last keyframe on frame number 41, and this one is the same as the First frame. So in order to see a perfect loop, we will end the cycle at the 40th frame. So that it will go to frame one right after frame 40.
要循环预览动画，在End frame框输入'40' 。我们有最后的关键帧在41帧，这一帧和第一帧是一样的。因此，为了看到一个完美循环，我们将结束周期在第40帧中。因此，它会在40帧后跳至第一张帧。

Step 29

Now we will tweak the motion just a little bit in between the main key frames. Go to frame 4 and rotate the foot so that it rests completely on the ground. Also pull down the main torso bone a bit. Do the same for the other foot and torso on frame 24. You can copy and Flip-Paste the pose from frame 4.
现在，我们将一点点的调整主要关键帧之间的运动。转到帧4并旋转脚，使其完全落在地面上。也拉下主躯干骨。在帧24做同样在另一只脚和躯干上，可以从帧4复制然后翻转粘贴姿势。

Step 30

To make it walk faster, you can move the key frames closer to each other. Alternatively, go to frame 1, with the timeline on frame 1, in the dopesheet editor. Press A to select all keyframes. Press S to Scale, move the mouse towards the left and then Left-click to confirm. I have reduced the walk cycle from 41 to 28 frames, and so the End Frame to preview the animation is 27. The walk cycle is now ready for export. Of course you can add more details.
为了使它走得更快，你可以移近的相邻的关键帧。或者，也可以用时间轴到第1帧，在摄影表（dopesheet）编辑器到第1帧。按A键选中所有关键帧。按S键缩放，移动鼠标向左，然后左键点击确认。我已经减少了步行周期从41到28帧，所以帧结束预览动画在27帧.步行周期已经准备好用于输出了。当然，你可以添加更多的细节。


In the Dope sheet editor, You can name this action as Walk, or anything you like. Drag the header of the dopesheet window, with the middle mouse button if you don't see the name box. And finally Save the file.
在摄影表（Dopesheet）编辑器，你可以命名这个动作为Walk，或任何你喜欢的。如果你看不到的name（名称框）， 用鼠标中键拖动摄影表（Dopesheet）窗口的标题。最后保存文件。
