I'm trying to do the simplest thing in the world - make some dialog images 50% transparent. I've spent the last half hour making different layer masks and nothing seems to work. So what's the right way to do this?
(When I'm asking about format I don't mean file format, I mean how is the alpha mask image supposed to encode the opacity)
Clarification: I would like to do this using the Set Dialog Item Alpha Mask trigger option
I would like to use the alpha mask feature. Exporting, editing, and re-importing 60+ images is not my idea of a fun way to spend an afternoon.
Edit: I realize my OP was slightly vague for those not super familiar with all the dialog triggers, so to clarify, there is a trigger called "Set Dialog Item Alpha Mask" - this is the method I would like to use.
Hmm, I tried this and the alpha value is having no effect on the image shown, even when I set it to zero. (The color value is definitely having an impact, so I know I'm applying the action to the right set of dialog items.)
