Note...:

Always make sure there is disabled compresion for textures on D3, this is already done in the Doomconfig.cfg, but if someone wants to use his own Doomconfig.cfg make sure to have this lines on it to be able to see the Relief...

image_usePreCompressedTextures "0"
image_useCompression "0"

If you typed this from the in-game console you need to type vid_Restart now to activate.

Original Doc...:

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.

This mod is dedicated to Id Software and all the people that created the original great Shaders mods.
