to make the alpha channel gunsight....
1. create a 128x128 grayscale image...fill it with black.
2. create a 128x128 RGB image.
3. in the grayscale image, create your gunsight design (using white for the actual sight and shades of gray for the glow effect.) including a glow effect to your desired taste. don't worry about color, this grayscale image is the alpha channel for the color.
4. save the grayscale image as a 256 color grayscale bitmap (there are several ways of doing this depending on the software you use....if you need tech support, i can help with photoshop mostly).
5. move to your RGB image now. select a color that you would like your sight to be (a bright green, yellow, or orange etc). fill the entire RGB image with this color.
6. save your RGB image as a 256 color bitmap.
the naming scheme is as follows:
gunsight.bmp ('gunsight' = any name you like)
gunsight_alpha.bmp ('gunsight' = any name you like)
they both have to be in the sights folder.
then when in AH choose the gunsight.bmp
that should do it.... if you need more help, feel free to send me a private message.
