I'm modifying a model and trying to add simple expressions like blinking and etc.

I'm trying to mirror a closed eye to the other side, but it causes the whole model to become symmetrical, I can't figure out how I can only mirror selected parts :|

Here's an example: https://www.youtube.com/watch?v=Qd4rqPp6hW0&feature=youtu.be

You can see his head shape and and parts of his cheeks are getting symmetrical

edit: another example, the difference between the basis shape-key and the mirrored one: https://gfycat.com/ThirdHealthyGalapagosdove

Thanks in advance!

Since many keys will deform the cheeks you might have to tweak the head to be symmetrical initially by deleting half the head and apply a mirror modifier. Then you can model back the asymmetrical features as a shape key to the head to bring it back to its desired shape. That is, if it is not a problem to keep the asymmetrical shape key to a value of 1 at all times.

If that is a problem then you'll need to apply that deformity to all the shape keys and the basis head so that eg: A blink left doesn't turn the head back into a symmetrical shape again.

The way I do it is turn all shape keys into individual meshes. Then copy all basis head mesh to pair with the all the shape keys mesh. All the basis heads copies get 2 keys the asymmetrical shape key and all the individual shapes like blink left key. While the basis copy head has both keys set to a value of 1 you create a shape key by selecting the basis copy head then select the original symmetrical basis head then Join as shape in the shape key's special menu.(down arrow)

When using shape keys in blender, under the settings, you can assign a vertex group to define the vertices being affected by the shape key.
