woah, a court jersey. anyways, never seen any like that, when i had an error on my jersey before, it was color grey.
try re-importing the buni file onto the fsh and when you import it back to the viv make sure you compressed the file.
well frAn you know why it was grey right? Because that is the color of the "xxxxlightmap.fsh" for the court. For dahl's practice court that is what the lightmap looks like, if you were to goto a different court the "jersey" would change.
