Alpha channel question

[Wingamez]

I am new to AC technique. So, here is what I need to do: I have a sprite (simple 24-bit *.*bmp image) with anti-aliased edges. In the picture editor I can do Transparency-AC-Edit-Show. I then see a black AC map, but the inside edges are not antialiased - they are sharp, and there is no shades of gray. So how do I edit it to apply shades of gray on the inside edges? Do I need to use a 3-rd party painting program to create AC in the first place before I import my sptite into MMF2? Hope that makes sense...

I appreciate any help.

The fish holds the answer.

(No really, click the little fish button, and then select "Alpha channel" in the properties)

That's what I did....and I see a black AC map with sharp edges on inside....no gray pixels.

Click on the "edit" box to the left while having the Alpha Channel option selected, and you'll see a grayscale-palette to the right. Use that and the drawing tools to change the alpha channel.

Oh, and kind of yes- it's easier to use PhotoShop or something and import PNG files into MMF for proper Alpha channels. Editing them in MMF can be time consuming.

You need to change formats. BMP doesn't use alpha channels at all. MMF can only open TGA and PNG files with alpha channel. I have had no luck with TGA myself yet, but PNG files with alpha channels work great.
