We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I've only found the way to control all the alpha values of images through "tint". But what I want is to change specific image's alpha value, even dynamically. Dose anyone know the answer? Thanks!

Found that I can combine "noTint" with "tint" to do what I want. So, problem kind of solved. Though, any other solutions will be appreciate, thanks!
