# Adding Visemes

### Separate Face from Body

Select your body mesh and press **"P"**, then select **"By Material,"** this will separate your face and body into two different meshes (if set up properly)

Name your meshes "Body" and "Face" respectively, you can select each mesh and rename it by pressing **"F2"**

<p class="callout info">**Doing this is more optimized than having your entire model one mesh!** This is because when you have a shapekey activated it calculates ***every*** ***vertex on the model,*** *meaning if you have too many it can cause lag.*</p>

### Create Visemes

In the CATS menu (Press **N** to open the side menu) and add each object like the following, and click **'Create Visemes'**
