Default Hair texture
Does any how to make a natural looking alpha channel for hair like NewSea's textures? I tried drawing them with had, but that doesn't seem to be working very well....

The image posted is NewSea's hair texture with alpha channel applied.

Don't draw the alpha channel. Draw the hair on a new layer, and base your alpha channel on the hair.

What do you mean by 'base your alpha channel on the hair' ?

And thanks for answering

I think what HP meant was to use the hair you are basing on to make the alpha.
For example, take the picture into photoshop, and draw around the edges, or play with the picture light levels so you build the alpha directly from there.

Particularly I prefer to make the alphas by drawing, my tablet is broken so it's hard to make it properly.
Many 3D artists draw alphas using strategical tweaked brushes so it helps a lot.
Instead of using a hair brush, there are many available at DevianArt if you want to take a look, I prefer to use just simple spots (1px) and apply settings to multiply them.
I think Photoshop comes with some presets you can use.

A quick example:





Always, ALWAYS, when making the alpha, create multiple layers so you can have more control.
And try always to leave only the tips with different lines, as the detail itself you will have to add on the texture.

If you are interested, there are tools that allow you to build amazing alphas, made specially for 3D artists, with a lot of maneuver of brushes.
I refer to Autodesk Maya, they have a big collection of brushes you can use.

I had a really good tutorial bookmarked somewhere around here, but this thing is a mess atm.
Hope it helped though.
