PHY is the extension for Source's proprietary collision model data format. It stores data for the rigid or jointed (ragdoll) collision model used by the MDL. In addition, it stores prop_data information about a model such as which gib-models to use if destroyed.
File Format
The first bytes of the file form the PHY header
struct phyheader_t
{
int size; // Size of header after this point (generally 16 for a total size of 20)
int id; // Often zero, unknown purpose.
int solidCount; // Number of solids in file
long checkSum; // checksum of source .mdl file
}
Todo: Document headers for each solid
Todo: Document "old format" if VPHY is not seen
Todo: Document key-value data for each solid
