Another thing which I have taken a look into, sticky lips! Currently it doesn’t work automatically in how it sticks together so that is something I will have to take a look at next. I don’t want the effect of it getting the same stickiness in the end as it is in the beginning; a little bit of the effect can be seen in this video, but most of it has been removed by hand. Not complicated but would be tedious if I have to check the whole animation and create the effect manually.
Something I noticed on my fleshy eyes was that it didn’t keep the thickness of the eyelids and just pushed the vertices away without thinking if there was a thickness or not. Luckily it wasn’t too hard to solve, threw in a lattice which then helped me avoid the problem.
