File Description

Parallax Mapping Engine 2.0 is a mod that implements parallax mapping technology into Quake 4. Also known as virtual displacement mapping or offset mapping, it is an advanced graphical technology that simulates physical displacements on textures, resulting in a fuller 3D experience. This is the sequel to the popular Doom3 Parallax Mapping 1.0. It incorporates an improved central shader and includes over 1000 custom heightmaps. All other textures benefit from the author's proprietary Simulated Parallax Mapping algorithm. The result is a significant improvement over standard bump mapping.

NOTE: This mod requires at least a Radeon 9500 or GeForce FX

Description:

Parallax Mapping Engine 2.0 is a mod that implements
parallax mapping technology into Quake 4. For those
who do not know, parallax mapping is an advanced
graphical technology used in next-generation titles
such as Unreal Tournament 2007 and Perfect Dark Zero.
It is also known as "virtual displacement mapping"
or "offset mapping." 

This technology adapts to the player's angle of view
and offsets surfaces, thus simulating physical 
displacements on the ground, wall, etc. This results 
in a fuller 3D experience.

Sequel to the popular Doom3 Parallax Mapping 1.0,
this mod incorporates an improved central shader and 
includes over 1000 custom heightmaps. All other 
textures benefit from the author's proprietary 
Simulated Parallax Mapping algorithm. The result is 
a significant improvement over standard bump mapping.

NOTE: This mod requires at least a Radeon 9500 or GeForce FX


Installation:

1. If you have other shader mods installed, remove them first
2. Extract the contents of q4parallax2.zip into Quake 4\q4base
   (You should now have the following folders in q4base:
    gfx, glprogs, models, textures)
3. Start Quake 4, and the mod will be automatically activated


Technical Notes:

- Make sure you turn on the Specular Map and Bump Map options
- All custom bump maps in user-made levels will automatically 
    have simulated parallax mapping. If you want your own 
    textures to take advantage of true parallax mapping, 
    please read the included tutorial.


Compatibility:

- This mod requires a Radeon 9500 or GeForce FX or above
- This mod is compatible with most other mods, except those 
    that modify the main shader


Troubleshooting:

If you see obvious graphical errors like black textures, 
see below:

Make sure you are using recent video drivers.

For Nvidia cards, if updating drivers doesn't help, 
do the following: 
1. Go to the folder Quake 4\q4base\glprogs
2. Open interaction.vfp with Wordpad or Notepad and delete 
   the line that says 
     OPTION ARB_precision_hint_fastest;
3. Save the file.

If you have any problems or questions, email me.


License/Permissions:

Please email me at junkguy@gmail.com if you wish to include
any part of this mod in your own Quake 4 project.

If you wish to distribute this mod in your own publication,
feel free to do so without asking for my permission, but 
please send me an email so I'll know.

You may distribute this mod, provided you include this readme
file and all the contents of the original zip file, with NO
modifications. You may distribute this file in any electronic
format as long as you include this file intact, with NO charge
(other than incidental charges for time spent on-line).
