I need to forwarn you that this is somewhat involved if you're NOT well versed with editing files. But with patience and reading this can be easy.
1. use nemons bundle extractor to extract the PATCH.BUNDLE file somewhere, prefferably onto your desktop for easy access.
2. once you have extracted the PATCH.BUNDLE file, you'll have a folder on your desktop named PATCH.BUNDLE.
3.Navigate to the folder PATCH.BUNDLE/data/settings. find an XML file named MATERIALS.XML.
4.right mouseclick on it, and click on EDIT.
5. Look for the first two entries like listed below(at the top of the file)
NOTE: I've highlighted the two parts that you need to edit. those values were by default set to alot less than what mine says above. I set mine to 150000 which should clear the clip plane completely off the map.
<clip_plane value="0 0 -1 150000"/>
<clip_plane value="0 0 1 -150000"/>
<!-- crosscom settings -->
<variable name="fog_start_end" type="vector3" value="160 7000 0"/>
6. once you've edited those two entries SAVE the file (not SAVE AS).
7.copy and paste the entire PATCH.BUNDLE folder into your GRAW/LOCAL folder.
8. open your GRAW/CONTEXT.XML and in the entry at top listed as English and change it to LOCAL
<script base="data" exec="menu/menu" editor="false" language="local"/>
9 SAVE the file and close it.
fire up GRAW and play.
Some notes: I've heard ruomors or issues that, when you set your graphics anti-aliasing to off, the clip plane shows up. when you set the feature to EDGE SMOOTHING, it goes away but the distance looks fuzzy.
This isn't the case with this edit.
