Ugh!I been a bad girl, please help!
All this time being a clothing designer, I have always used the targa plugin that makes it so you don't need to make alpha channels, and I have read and read and been told to stop doing that lol So that is what I am trying to do...
I know how to make an alpha channel, but I don't know how to make it do what I need it to do... for example...
I am making some capris, and they will be cuffed at the bottom with a drop shadow, but when I make an alpha channel for them my lovely shadow turns into a semi-transparent white color ... I have made the alpha over and over and it still happens, I don't know what I am doing wrong.. I have looked for an answer throughout the forums but haven't had any luck..
Can someone please help me? I hope I am making sense, I am so frustrated lol

lol okay I'm assuming you've read through Chosen's sticky about alpha. If not, read that. Now, I can take a guess at your specific problem from this statement: From: Sensual Casanova when I make an alpha channel for them my lovely shadow turns into a semi-transparent white color Make sure the background color isn't white. Obviously the first step is to have a background. People used to doing png transparency or whatever will often delete the background layer so that they only have transparent layers, but with an alpha channel you actually want a background layer. The background is visible in Photoshop, but the alpha channel makes it transparent in SL. So make sure you have a background to your image, and then color it appropriately. Ordinarily I would say color it to match the pants, but it sounds like you actually want a semi-transparent black shadow, in which case make the background black.

Put a black layer behind your transparent layer.
What is happeneing is that you have an area in the clothing texture that is fading from solid colored to transparent, right? If you right click the layer icon and choose "Select Layer Transparency", and make an alpha channel from that, you're on the right path. But if you save the file as a TGA and there is nothing dark behind the area where it is becoming transparent, then the semi-transparent parts anti-alias to clear, and that looks white in SL. If it is anti-aliasing to the black layer below it, which it will with that layer added, then the edges of the shadow are dark, not white.
