This is my first attempt creating a plugin with 3d Max SDK. The work is still in progress but I am pretty happy with the outcome so far. The main deal of this plugin is to create the effect that simulates muscles sliding underneath the skin. My plan now is to polish this plugin, add some more functionalities and post more illustrative examples here soon.
The following links are the references I used on this research.
