//! HairAsset is a simple AssetData wrapper around the TressFXAsset used by the AP.

//! Is comprises of the hair vertices data file, the hair bone skinning information file
|
|
//! and the collision data file.
|
|
//! The plan is to separate the collision data as it can have the relation of 1:1, 1:N or N:1
|
|
//! meaning that the hair can have multiple collision handling (not only single mesh), and at
|
|
//! the other end multiple hairs can have the same collision (hairdo and fur for example).
