A pic in the screenie thread reminde dme of a small range scale mod I made a while ago for the Smerch radar.
Move the textures smerch_radar25.zip into the cockpit folder
Edit the avionics ini, add/replace existing entries with the data below:
[TextureData] RadarTexture=cockpit\smerch_radar25.bmp RWRTexture=cockpit\rwr.bmp ;RadarTextureSize=256 RangeTexture[1]=cockpit\Radar_range1.tga RangeTexture[2]=cockpit\Radar_range2.tga RangeTexture[3]=cockpit\Radar_range3.tga [AvionicsData] AvailableModes=SEARCH,ACQUISITION,TRACK,BORESIGHT RangeUnit=KM RangeSetting[1]=30 RangeSetting[2]=60 RangeSetting[3]=120
StartRangeSetting=2
This change makes the selected range scale visible,
the selected scale is shown in the top center of the radar scope.
