Are you using a sprite shader? If so, separate your alpha channel and
multiply it by a scalar that represents the value of the overall
presence of your "letter A." So, basically, you end up manipulating
your alpha channel so that it ranges between 0 where there is never any
image and the alpha value of the fully present part of the image. So,
if it's 50% opaque, the alpha goes from 0 to .5.

Hello,
I have a polygon which has a texture mapped on it. The texture has
an alpha which is used to mask out unwanted areas of the image. All
unwanted areas should be transparent. I can construct this appearance
but I am finding that I am unable to fade the positive part of the
image in and out.
For example, if I had a card, and I textured the letter A on the card,
only the letter would be visible, everything else on the card would be
transparent. Then I want to dissolve the letter in and out at will
while maintaining the base transparency.
I have tried constant shaders, sprite shaders, layers etc. I have
manipulated mask connections, alpha connections, but still I can find
no way to accomplish this. Any suggestions would be greatly apreciated.
