PSE 10 Alpha Channel question

[SebastianL]

Hey, not sure if these are the right forums to be asking about pse, but anyway, hopefully someone can help me out...
I'm using pse 10 to create textures for 3D models which I'm going to be using in the game engine 'unity'. Unity reads specularity maps from an images alpha channel, but I'm not sure how to edit the alpha channel in pse. Thanks for your time!
