Tatoos and Opacity?

[cocobee]

I know how to put the tat and which arm and all that, but (in EA Graph)when i try to put the opacity to "0" so only the tat will show up in the game. The opacity doesn't save (i push the sve button and it looks correct, but then I'll re open the file and it's the same as it was when I started.
Basically, how do you save the Opacity to "0" and keeping it that way?

thanks in advance 8)
