I´m not getting blast radius shown

[DRG]

The blast radius is set to be off under normal circumstances unless you turn it on manually in the arty screen

However:

IF you want to see the blast radius all the time open up the CamoGame.ini found in the \Game Data folder and look for this line

;show or hide secondary blast areas 1=on, 0=off
ShowBlastCircles=0

change that to

ShowBlastCircles=1

DO NOT use something like WORD to alter that file. Use "Notepad"
