STUD/Entity Definition

003 files are complicated STUD files, for this particular STUD file it's easier to parse it per instance record rather than from the first instance header.

This page will only be describing the STUD file on a per-instance basis.

Common Types

 struct record_t {
   ulong padding;
   ulong key;
 }

Notes

1. offset_grouping points to a reference array definition, each reference should be grouped together per indice. Key is local instance ID.
