From the modder: I altered the Cell.dds file to give a less obtrusive gridlines, the default blue glowy squares i found ugly and obscured the pitch textures a little too much, it ain't perfect (i'm still new at this ^^) but i prefer it over the original. To use, backup then replace Cell.dds in Program Files/Cyanide/Blood Bowl/Data/3d/Gui/Cells/Textures/
