View Full Version : No Alpha????

07-24-2003, 01:52 PM
I created a lower 3rd banner in PS7 with alpha and saved it as a tif. The banner loads without a problem but the alpha doesn't seem to exist.

I check the banner by pulling into AfterEffects and thealpha worked perfectly.

Any Ideas?

I think I'm having this same problem. I've created a graphic in Aura for VT[3] and when I export it, including the alpha channel, for use in the Character Generator, the Alpha Channel doesn't exist.

Is there a way to reach the alpha channel or use a key effect to take out the solid color it used to replace the alpha?

The early release version of PS7 had a problem saving alpha information. You might check to see if there is an update available.

I used Aura which came with VT[3] for this and it was giving me that problem. It works fine when I open the file in windows or other viewing programs... but in CG I can't make use of the Alpha.

The CG does use alpha as I am using it in a different part of the title.

I just tried this with Aura, and the image works fine with Alpha in my CG.

Don't forget that to save a file with alpha from Aura you must a) choose a 32bit filetype, b) set the File>Export>Alpha Channel setting appropriately (in this case, 'no premult') and c) set the Project Window background to 'None'.

Thanks Steve...

That was my problem... if all else fails.. read the manual... AGAIN..

Read it wrong and though that you needed the checkered or the other background and that None would give you no alpha... Thanks.

Glad it worked out1

Would have been nice when you export formats that
support alpha Aura would
display a , "ya want alpha?", box.
Little things like that make a world of difference
in first time experience. ;)

Paint Shop Pro or Photoshop had that where you can select your transparency upon export... Very useful indeed.

Mirage has totally revamped the export interface and all the choices are now very apparent all at once.

Diving back into Mirage some now myself,
is this ever a deep piece and powerful of software.
The more I learn, the more I realize how much I have to learn.
