After downloading the patch and putting it on Morrowind, everywhere in my game seems to be in darkness. I dont know what its like in the sun, being a vampire and all.
And it seems that it did nothing for the Skall Attack quest, the console command for the journal would be great...

Well if the indoors is in darkness too, then just turn your gamma correction up =o)

IS it just Bloodmoon thats in darkness? or is Morrowind and Tribunal also? If its all three, I would seriously try turning up the gamma, or just try re-installing Bloodmoon and the patch. I beliieve the only patch I have for Bloodmoon is the No-CD patch.
