Need help with transparency map, maya 8.5
I'm having trouble getting a perfect transparency copied into my alpha map in photoshop.. i seem to be getting a white haze around the actual hair fibers and i don't know how to get rid of it... or for that matter how EXACTLY to copy an alpha selection period without the stinking magic wand which never does a good job with gradients.

before selecting, up the contrast then select the negative rather than positive space.
then invert
The grey in the texture seems to come from the fact that you are getting a white background on your texture, try using a black background instead of transparent.
You can also just copy/paste directly into the alpha channel. I normally create a layer group in the normal color channels which will contain my alpha. This means you can use all the regular image adjustments, multiple layers, etc. Then just copy it over to the alpha channel.
But... As ivars said, I think the white halo is because there is white in your color channel, either fill it up with as close a color as possible, or fill it with the clone tool so it matches the hair perfectly.
if you've got it as a layer, you should be able to just paste it straight in
worked for me in 6 and cs2
