yep.. even if bc wont display it, it will always generate shadows or lightmaps for everything.. it just gets bf42.exe to do it for you.. at which point its always looking at the entire map. not the bc version
I was guessing some sort of light-setting being messed up.. Does this occur only on the 1 map you are working on? or others as well? Holla if you need any help from SuperChicken
