An issue that comes up repeatedly is how to merge several geografts to a character. The necessary merge information is stored in the meshes when they are imported. However, the information consists of vertex number, and is thus corrupted if a mesh has been edited, e.g. by merging other geografts to it. Therefore, one must follow a strict procedure when merging several geografts:
- Hierarchal geografts, i.e. geografts for geografts, must be merged first.
- All geografts on the same level much be merged with the character at the same time.
Let us show how these rules work in practice.
