This is something that I know wasn't a problem before, but recently I saw one of my customers flying the one cloakable ship I sell. He was flying it around cloaked, but the invisiprim used to hide the AV was rendering with a bland gray texture.
I rez'd the same ship from my inventory and it cloaked with no problems, so I gave him the copy I had and it still had the same problem.
Did LL do something, or is there a current bug that causes the NODRAW texture when called by a script to not apply properly for someone who is not the creator? I even tried the other nodraw texture ID and it again worked fine for me, but not for them.
If anyone knows the reason for this that can enlighten me, or if there's a work-around I would be grateful, as I've seen plenty of cloaking devices that obviously still work, so I'm not fully sure why mine would not all of a sudden.
