How to remove camera Shadow?

[vac333]

I have been trying to turn off the radius shadow linked to the camera, but have not been able to find the setting. This is a shadow which is directly linked to the camera position, when you change camera angle the shown moves with the camera in such a way that when scrolled into character the shadow is centered on character, when you scroll out from character the shadow stays centered with the camera potion such that it is no longer over the character. I have been able to reduce it's radius with these setting:

flocalShadowMapHalveEveryXUnit=0

focusShadowMapDoubleEveryXUnit=0

fShadowBiasScale=1.0000

fDirShadowDistance=-3000

uiOrthoShadowFilter=1

uiShadowFilter=1

iShadowMapResolution=-1

iDirShadowSplits=2

iMaxFocusShadowsDialogue=4

iMaxFocusShadows=1

fBlendSplitDirShadow=0.0000

bSinglePassDirShadow=1

bAllowShadowcasterNPCLights=0

fMaxFocusShadowMapDistance=-540

in Falliut4Prefs.ini

There must be a setting I am missing, please if anyone understands this and knows how to remove the camera shadow completely, post here

What's with all the -ve values? That can't be good.
