.PHY File Extension

3D model file created by 3ds Max, a software package used for modeling and animation; defines how a 3D skin looks when matching a biped skeleton's movements; allows the biped's physique to capture motion properties such as bone rigidness, muscle bulging, and tendon stretching.

The physique data stored in PHY files can be reused across multiple biped models.

Data file saved by PhyMod, an older physical modeling software program; can create and modify electronic sounds.
