I am making a simple leaf using an alpha map just to get used to the process for future reference. I am glad I am doing it now, cause nothing I am doing is working. I have an alpha map where the white will be visible and the black is going to be transparent. I put in through the materials and click the alpha button under the texture panel. I have tried Uving it onto it, using texface, basically everything and nothing works. I am looking at an example file and I have the exact same settings and it still isn’t showing. I can show a screenshot of my materials panel if you need it. Thanks in advance.
When you load the Alpha map, make sure to turn off the UseAlpha button in the Map Image panel. Since the black and white image does not actual have an alpha channel.
then map the black and white image to Alpha, not to Color. Where the image is black, the alpha will be 0 (transparent). If you want it reversed, click the Alpha button again. http://wiki.blender.org/index.php/Manual/Map_To
Ok I got a little progress. I got it to where I can see the image I want in the texture panel and where the black is transparent. I just can’t get that translated over to the render. Nothing I do will change it. It should be working right now. Thanks for the replies so far!
Post your blend so we can see the problem. What is the problem with the render?
Okay, got the file uploaded along with the material and texture panels. So have at it, I can’t seem to get it working

Turn on Ztransp and drag the A handle to zero which is located under the color info under the material tab
^^^That’s correct. I also had to turn off UseAlpha for the mask texture in your blend file. The image doesn’t seem to have an alpha channel.
It works!! Thanks a lot guys! And yea I found a way to get the alpha channel to work. If you hit CalcAlpha in the texture panel it will take out all the black. Thanks a ton guys!!
Got an new problem though. Once you do that there is a white outline around the whole thing? Is there any way to fix that? Thanks in advance!
