This week’s focus is on how to use the retopology tool to create a low-resolution model on top of a high-resolution model. This technique is very important when creating models of people and creatures. Because if this kind of model is to be animated, the modeler needs to arrange the wiring of the model properly. For example, the eyes are the most varied in the expression animation, so there needs to be enough extension lines around the eye sockets. There is no muscle deformation and bone movement in the skull, and the wiring here only needs to be fixed. The shape of the ear is complex, but it needs dense wiring for the purpose of adding detail. The modeler can use the retopology tool to create half the low-resolution model on the right side of the high-resolution model, and then use the mirror tool to mirror and copy the left half of the model.
At the same time, we learned about the sculpting function in maya. We can simply sculpt the model in maya. Also, when we do the blend shape, we can use the sculpting tool to make expressions on the character model. The blend shape tool can be used to control the character’s facial expressions if the character does not have a face binding.
