ETXreaL is a graphics mod for Wolfenstein: Enemy Territory using the enhanced XreaL id Tech 3 GPL engine.


ETXreaL id Tech 3 Features

* Modern OpenGL 3.2 renderer with all deprecated OpenGL calls removed
* Clever usage of vertex buffer objects (VBO) to speed up rendering of everything
* Avoids geometry processing each frame using the CPU (worst bottleneck with the Q3A engine)
* Renders up to 500 000 - 1 000 000 polygons at 80 - 200 fps on current hardware (DX10 generation)
* Optional GPU occlusion culling (improved Coherent Hierarchy Culling) useful for rendering large city scenes
* Doom 3 .MD5mesh/.MD5anim skeletal model and animation support
* Unreal Actor X .PSK/.PSA skeletal model and animation support
* True 64 bit HDR lighting with adaptive tone mapping
* Advanced projective and omni-directional soft shadow mapping methods like EVSM
* Real-time sun lights with parallel-split shadow maps
* Optional deferred shading
* Relief mapping that can be enabled by materials
* Optional uniform lighting and shadowing model like in Doom 3 including globe mapping
* Supports almost all Quake 3, Enemy Territory and Doom 3 material shader keywords
* TGA, PNG, JPG and DDS format support for textures
* Usage of frame buffer objects (FBO) to perform offscreen rendering effects
* Improved TrueType font support that does not require external tools
* Linux 64-bit support
* Linux sound backend using SDL
* .avi recorder from ioquake3 including sound support
* Optimized collision detection routines
* Support for Omni-bot
* GUID system to generate etkeys which are sent as cl_guid


System Requirements

Minimum system requirements:

CPU: 2 GHz Intel compatible
System Memory: 1024MB
Graphics card: Any graphics card that supports Direct3D 10 and OpenGL >= 3.2

Recommended system requirements:

CPU: 3 GHz + Intel compatible
System Memory: 2048MB+
Graphics card: Geforce 8800 GT, ATI HD 4850 or higher.


Future Plan

* Add a Creative Commons BY-SA high resolution texture replacement pack including new material definitions to support diffuse, normal and specular textures
* Create improved versions of existing maps with an etx_ prefix like:
* Improve ETXMap ET .map -> Doom 3 .map format conversion routine to handle spawnflags -> boolean type conversions
* Improve ETXMap compiler for better support of extracting models from .bsp files for further editing in Blender or other 3D tools
* Finish Doom 3 style DarkRadiant entity definitions file etmain/def/entities.def to have full support for all ET entity types
* Add Blender tools to make it easier to replace the existing models
* Optimize ET decal system with VBOs
* Add Bullet physics engine (maybe)

Just extract it somewhere and copy pak0.pk3 - pak2.pk3 from your Wolf:ET installation to ETXreaL/etmain/.

Then start ETXreaL/bin/<yourplatform>/etxreal.

Yes, but must be compiled with Visual C Express 2010.

The compiled executables are distributed within the 0.3.0 release.

Ugh, tried to run this on my old pc with no luck. Unfortunately it seems my geforce 6600 is unable to run it. Is this going to be permanent? Couldn't you guys simply make most advanced graphics features optional?

Reply Good karma Bad karma+3 votes

I'm afraid yes. The Nvidia 6XXX generation does not support OpenGL 3.2

We require OpenGL 3.2 compatible cards and there is no real change to undo that. OpenGL is required for the lighting, special maps and anti aliasing, without it, you're back at Wolfenstein Enemy Territory.

Looking forward to 5 Nov.

I am so excited for this mod, not just to have good old wolfenstein:ET with better visuals. But also because of this great and more modern engine that you have created, we can finally have some Linux games that don't look like they were made in 2004 or below, this is source engine level graphics capabilities, from what I can see with the textures even better than that. And of the best things of all, people who are used to the ioquake3 engine and practically breath it don't have to change to a brand new engine. Thank you so much for your contribution to the open Linux engines.

For a beta, the amount of work and changes, visual changes, is simply over everything. Plus the new graphic features such as Parallax, Bloom, HDR... Nirvana pal.
