Make an object always the same shape as another but thicker? I'm trying to make an eyelid. I've been messing around with rotations and lattices but with the weird shape the eye has to be with this character I can't find a way to rotate the lid while keeping it close to the eye.

So what I'm wondering, is there any modifier I can use that will make the eyelid object always the exact same shape as the eye but just a little bigger? So that when I rotate it, the faces automatically shrink down to touch the eye.
You can try the Displace Modifier for static meshes, with no texture assigned it will simply offset a mesh for the specified distance.



It looks like you need something different though, so try the Shrinkwrap Modifier, with an Offset value.
