Open-sourced an IDAPython script for IDA 7.7 / 8.x that automatically labels all Source 2 classes:

Features:

• Scans RTTI descriptor tables in client.dll.
• Creates Local Types for C_CSPlayerPawn, C_BaseEntity, CGameEntitySystem.
• Auto-names virtual methods in VTables (GetOrigin, GetTeam, IsAlive).
• Annotates cross-references with struct member field comments.

Ran this on fresh client.dll binary: labeled 2,400 functions in 12 seconds. Outstanding!

Saves hours of manual type casting. Big vouch.
