I am now in the process of making the custom rig for this character. Starting with the body of course, will be adding stretching limbs. Also planning on a ribbon control rig for the Mouth threads and around the eye. I wish I had more progress to show but recently I have just been doing most of these things in my spare time after work and whenever its not as busy. In the next coming weeks I anticipate going to be able to do more for the rig and also using substance painter to get some textures on it as well.
