Last week the rig bindings for the head model were completed and the initial weighting done. This week’s Maya head model is building on last week’s work to fix the details and make changes. The reason for the fix is that we need to use this model for animation. The animation process can be difficult to fix if there is a problem with the model or the weights, so we spent the whole week modifying the model and weighting details.
The weights were divided into three groups, the first group being the head and upper jaw, the second group being the lower jaw and the third group being the neck which never moves. The detail of the weights is very important, as I had a small spot in the inside of the mouth that was not painted as a head weight which caused the model to fall apart when animating the opening. After that it took me a long time to find the problem and fix it.
Incidentally, the model of the teeth was also created following the steps of the teacher based on the last model. And made the upper teeth and upper jaw bound into groups, and the lower teeth and lower jaw as well.
