The RL character base model has been developed to be a one-size-fits-all generic approach which allows for modeling and animating both realistic and stylized characters. Apart from the jaw, teeth and eyeballs, facial animation is purely morph driven – and as such it’s important to bear in mind when modeling that if the base mesh interpolation – its existing relative balance – is radically altered – that this can have negative effects on morph interaction. This is not an an issue of shape – it’s about vertex pattern and how, when modeling – it’s important to maintain good balance and the best possible relationship between the modeled mesh and the original base. Not do this – for example, simply to conform the mesh and reposition vertices without reference to the original base can create many issues which will need to be resolved later.
The Face
The ideal way to ensure that mesh balance is retained is to, on a regular basis, morph the modeled CC mesh back to the base to see how the mesh pattern is affected – whether the mesh is becoming overly compressed or overly stretched in places. Particularly, issues will occur where the mesh becomes relatively bunched, stretched and/ or incorrectly occluded at areas such as the mouth corners, lip inner edges, eyelids, eyelids edges and eyelid corners – though issues may also be noticeable in the areas of the eye bags, under brows as well as nasal creases. Please do check these areas regularly throughout the modeling process. As well as checking via morph to base and back, please do test animation (ideally and most quickly via a short test sequence) on a regular basis during modeling as this will help reduce the amount of clean up which may be required later.
Major Regions
This section will cover the major regions of the face which can be further broken down into two subcategories:
| Regions of the Eyes | Regions of the Mouth |
|---|---|
Brow Ridge Apex
Eyelid Crease
Eyelid Rim
Eye-bag Crease |
Nostril Crease
Inner Nostril Ridge Cheek Inner Crease
Philtrum Ridge Lips Outer Ridge
Lips Inner Ridge |
