brush
name "LoadScreenCharacterTech"
content "Simple"
fileName "Startup_Loadscreen0"
pixelBox [ 1496 , 0 , 441 , 749 ]
brush
name "LoadScreenCharacterPsi"
content "Simple"
fileName "Startup_Loadscreen0"
pixelBox [ 748 , 1059 , 441 , 749 ]
brush
name "LoadScreenCharacterPhase"
content "Simple"
fileName "Startup_Loadscreen0"
pixelBox [ 1190 , 1059 , 441 , 749 ]
Now change all the pixel box numbers to " 0 ".
