Deformable Meshes

While stored in UTF format like most other assets they have a different structure to rigid meshes (VMesh).

Deformable Model

Deformable models are always compound, consist of multiple parts representing bones of skeleton. Skeleton hierarchy is defined by Cmpnd much like rigid compound models are.

MultiLevel

Mesh data is stored within MultiLevel entry located in UTF root entry.

Deformable meshes aren’t shareable between files, meshes defined within .dfm file are in local scope.

Single-part rigid meshes also happen to use entry of the same name to store VMeshPart/VMeshRefs for each LOD, however contents of MultiLevel for deformable mesh are different. Luckily you can avoid mixing the two by checking presence of Cmpnd within UTF as well, as rigid model has either Cmpnd or MultiLevel but never both which is the case only for deformable models.
