Duke Nukem Forever 3D Realms When it's done Build 613
  • Duke Nukem Forever is NOT using Unreal Engine 2. It's still a based on heavily modified Unreal Engine 1 build 613, which supports Hardware Brush with Static Meshes, Height Field Terrain etc.

DNF developed history:

  • early 1997: 3D Realms, started the DNF project with their own PREY engine.
  • summer 1997: changed to id Software's QUAKE 1 engine.
  • winter 1997: upgraded to id Software's QUAKE 2 engine.
  • E3 1998: Released on QUAKE 2 engine based DNF at E3.
  • summer 1998: changed to Epic Games' UNREAL engine.
  • autumn 1999: upgraded to the Epic Games' UNREAL TOURNAMENT engine.
  • summer 2001: they have written a tremendous amount of their own rendering system.
  • summer 2002: updated to the Unreal Engine 1 build 613 stuff such as HARDWARE BRUSH WITH STATIC MESHES, HEIGHT FIELD TERRAIN and more.
  • winter 2003: they have a 100% REWRITTEN RENDERING CODE and PHYSICS ENGINE, GAMEPLAY TRIGGER SYSTEM, AI SYSTEM, SOUND SYSTEM a.s.o.
  • spring 2005: included MEQON Physics Engine.
  • late 2005: once again 100% REWRITTEN RENDERING CODE.

Currently DNF engine Spec

  • massive heavily modified Unreal Engine 1 build 613
  • uses a Unreal Engine 1 Core System Technology
  • uses a Unreal Engine 1 Based Framework
  • uses a Unreal Engine 1 Based Trigger System
  • uses a Unreal Engine 1 build 613 techniques such as Static Meshes
  • heavily modified Unreal Engine 1 based UnrealEd 2.0 called the DukeEd
  • 3D Realms own Rendering engine, Sound engine, Gameplay trigger system, AI system
  • Meqon Physics Engine
  • uses a Unreal Engine 1 Based UnrealScript Programming Language

Discussion

Xian: So from what I understand, UE1 officially stopped at build 613 (used for licenses) which include a prototype version of what UE2 features, am I correct ?

El Muerte: no, there is no official "end" of UE1 or "begin" of UE2.

Xian: I see. So all those "new" features are things each developer added by themselves?

El Muerte: yes and no, in quite some cases licensees added features, but it also happens a lot that they backport features of newer versions of the engine, rather than completely upgrading to the newer version of the engine. For example, if you're using version 600 and have most of it nailed down and stable, you don't want to migrate to version 700 just for one new feature. You would backport it to version 600. It's much less work. You should take the engine version information about 3rd party titles with a grain of salt.
