parley voo onglaze?

are you wanting individual GUI elements to have different alpha values?

in short you can't, as standard, though you could probably write your own GUI element to provide this.

but you can give different types of GUI elements different alpha values, this can sort of be seen in the MeshViewer example which gives each set of GUI elements full alpha at the start so they're not transparent.

Hello, you did not understand, all my GUI element are transparent, as in the picture, but I want them normal, I do not know where I was in error set them transparent.

The UserInterface tutorial has a scrollbar that changes the transparency of all of the gui elements. You can copy your code from there.
