sorry, I missed this thread... a student of mine alerted me to it...
ok Multiface sculpts... yes it is an xml hack... and i will give credit to the guy who found the hack, just not here.. I dont want him inundated with IM's.. he just kinda found it, released it, and said 'there it is, explore it'... and a few have...
actually Builders Brewery teach a class on this (yeah ok, I am the teacher) and always, classes are free... if you wanna donate half a million linden dollars, I wont complain! but the point is, the guy who discovered this hack released it to everyone, and some have explored it.. and thats the point.. it is free. certainly not worth a million L$
i am no expert on xml.. just explored this hack and willing to pass my knowledge on
