在Blender创建面部动画系统第一部分 Create a Facial Animation Setup in Blender - Part 1

Step 21

我们再次将这种形状一分为二。按TAB键，退出编辑模式，提高值滑块到1.00 。

Press the down Arrow button and select New Shape Form Mix
按向下箭头按钮，然后选择New Shape Form Mix（新形状混合型）。

Step 22

Select the original shape key - EB-corner, and rename it EB-corner.l for left. Under Blend, assign the Left vertex group so that it only affects the left group. Similarly, do the same for the new shape key - Rename it EB-corner.r, and assign it to the Right vertex group.
选择原始的关键造型--EB-corner,命名为EB-corner.l 在Blend下，指定左顶点组以至它仅仅影响左边的组。同样的，命名新的关键形状EB-corner.r，指定给右边的顶点组。

Now all the shape keys for the eyebrows are done, and we will move onto the eyelids.
现在所有的眉毛的关键造型都已经完成，我们将移步到眼睑

Step 23

Create a new Shape Key. Make sure that all the keys are at 0.00. Click on the + (plus) button to add a new Shape Key. Name it EL-upper-up (for the upper eyelid moving upwards.)
创建一个新的关键造型，确保其它的所有关键造型为0.00.点击+号按钮添加一个新的关键造型。命名为EL-upper-up （表示上眼睑向上移动）。

Step 24

In Edit mode, pull up the upper eyelid. It's also a good idea to check from a side view too.
在编辑模式下，拉起上眼睑。从一个侧面来检查是一个不错的主意。

Press TAB to exit Edit mode.
按TAB键，退出编辑模式。

Step 25

Now again, (like we did previously) duplicate this shape key. Select the new key and increase the Value to 1.00. Click on the down Arrow button and select New Shape Form Mix.
现在再次， （就像我们以前所做的那样）复制这种关键形状。选择新的关键形状，增加值1.00 。点击向下箭头按钮，并选择New Shape Form Mix（新形态形态组合）。

Rename the keys with the .L and .R extensions. Assign the Left vertex group to EL-upper-up.l, and the Right to EL-upper-up.r.
重命名造型为.L和.R，再次指定左顶点组为EL-upper-up.l, 右为EL-upper-up.r.

Step 27

Next create a new Shape Key for the upper eyelids closed. Make sure all the keys have a value of 0.00 before creating a new one. Click on the + (plus) button and name it EL-upper-closed.
接下来，创建一个新的关键形状用于合闭的上眼睑。创建一个新的造型前确保所有的按键为0.00。点击+ （加）按钮，并命名为 EL-upper-closed.

Step 28

Press TAB to edit the geometry. Pull down the eyelids and the adjoining vertices to give it shape, and remember to check from the side also.
按TAB编辑几何。拉下眼睑和相邻顶点给它的形状，记得也从侧面检查。

Step 29

Press TAB to get out of Edit mode. Again, we will duplicate it and assign one to the left and a new one to the right. Turn up the Value slider to 1.00, press the down Arrow button and select New Shape From Mix.
按TAB键离开编辑模式。再次，我们将它复制和分配一个为left和一个为right。调高滑块值到1.00 ，按向下箭头按钮，然后选择New Shape From Mix（新形状从MIX ）。

Step 30

Again, like the others, rename the keys with the .L and .R extensions. Assign the Left vertex group to EL-upper-closed.l, and the Right to EL-upper-closed.r.
同样的 ，像其它的造型那样加.L和.R扩展。指定左顶点组给EL-upper-closed.l, 指定右顶点组给EL-upper-closed.r,

Step 31

Now we will create a new shape key for the lower lid movement. Make sure all the values are back to 0.00. Click on the + (plus) button to create a new shape. To save time, we will name the new one with the extension .l, as in EL-lower.l.
现在，我们将创建一个新的下眼睑运动关键形状。确保所有的值回0.00 。点击+ （加）按钮来创建一个新的形状。为了节省时间，我们将命名新的使用扩展.L ，如EL- lower.l 。

Step 32

Press TAB and edit the shape. The lower eyelid does not go all the way up to the top. Again, check form the side also.
按Tab键并编辑的形状。下眼睑闭合到顶部。再次，在侧边检查。

Step 33

Press TAB to exit Edit mode. Again we will duplicate this key to split it into the left and right shapes. Increase the Value slider to 1.00, and click on the down Arrow button and select New Shape From Mix.
按TAB键，退出编辑模式。再次，我们将复制此键将它分成左，右的形状。增加值滑块移动到1.00 ，点击向下箭头按钮，然后选择New Shape From Mix（新形状从MIX） 。

Step34

Select the previous shape key (EL-lower.l) and assign it to the Left vertex group. Select the new key and rename it EL-lower.r and assign it to the Right vertex group in the Blend options.
选择上一个关键形状（ EL - lower.l ） ，并将其分配到左边的顶点组。选择新的关键形状并将其重命名EL- lower.r ，在混合选项指定给右顶点组。

Our eye shapes are now complete.
我们的眼睛的形状已经完成

Step 35

We will now move onto the nose area. Click on the + (plus) button to add a new Shape Key, and rename it Nose-up.l
现在，我们将移到鼻子部位。点击+ （加号）按钮添加一个新的关键形状，并将其重命名为Nose-up.l

Step 36

Press TAB to edit the mesh. Select a few vertices around the nose and move them upwards.
按TAB键编辑网格。选择鼻子周围的几个顶点，并把它们向上拉。

Step 37

Press TAB to exit Edit mode. Duplicate this key to make one for the left and one for the right side. First increase the Value slider to 1.00 and then add a New Shape From Mix.
按TAB键，退出编辑模式。复制这个关键造型一个为左，一个用于右侧。首先增加值滑块到1.00 ，然后添加一个New Shape From Mix（新的形状从混合）。

Step 38

Rename the new key Nose-up.r and assign the Right vertex group to it. Assign the left vertex group to Nose-up.l
重命名新的关键造型为Nose-up.r 并指定给右顶点组给它。指定左顶点组给Nose-up.l

Step 39

Similarly, create another Shape Key for Smile.
同样地，创建另一个微笑关键形状。

Step 40

Press TAB and edit the mesh to get a good smile. I use soft selection to move the surrounding cheek muscles also. Remember to check the points from the side.
按Tab键和编辑网格，以获得良好的微笑。我用软选择移动周围的脸颊肌肉。也记得从侧面检查。

By now you should know how to split the key into left and right. Duplicate the key and assign one to the left and other to the right vertex group. Rename the keys as well.
现在，你应该知道如何分裂的关键造型为左，右。复制关键造型和一个指定左顶点组和一个为右顶点组。重命名键也是如此。

Step 42

Create a new Shape Key for Frown and name it sad.l.
创建一个新的形状为皱眉，并将其命名sad.l.

Press TAB to enter Edit mode and move the corner of the lips down. Also Rotate them a little bit. Use Soft Selection or the Proportional editing tool to help with this.
按TAB键进入编辑模式，将嘴角稍稍下降。还旋转它们一点点。使用软选择或比例编辑工具，以帮助你做这一点。

Step 43

Drag the Value slider to 1.00 and duplicate it (create New Shape From Mix).
值滑块拖动到1.00和复制它（创建新的形状从MIX ） 。

Step 44

Rename the new Key sad.r and assign the Right vertex group to it. Also assign the Left vertex group to the sad.l shape key.
重命名新的关键造型为sad.r和指定右顶点组给它。还指定左顶点组到sad.l关键形状（造型）。

Step 45

Create a new Shape Key (by yourself!) with the upper lip deformed, as shown in the image. This one is to express a feeling of disgust or irritation. We need to split this one into left and right keys.
创建一个新的上唇变形的关键造型（由你自己！）如下图。我们需要分为左，右关键造型。
