so im new to blender and im trying to do two different renders, one of them im trying to change the Disassembly Drones eyes to the X but I have no clue how and the 2nd is that when I go into viewport shading the eyes are just straight up gone. 

Now with the mouth, im trying to open the mouth of the drones but have no clue but I am also trying to do V's iconic smile but the mouth clips through it.

So, it's recommended to use cycles for newer versions, and for the mouth, make sure you have all shapekeys set to 0. and only use the "wide_mouth" slider in the main mouth bone.
