I'm working on a hairs but it's very hard to make the transmap.

Have you a tuto for make it ?

Here the exemple of the hair.

Thanks !
Olitoth.

look at other hair product's transmaps, and thier material settings.

The problem is drawing the fringe.

My advise...

1. Paint bucket the area black and set document to grayscale.
2. Use single pixel selection tool to select edge across the image to be the fringe.
3. Apply noise filter to get black and white specks in that selection.
4. Set a hard edge smudge brush to "lighten" and pull the dots into strands holding the shift key to get straight motions.
5. Use Levels to get bright white and black with good transitions.
6. If you need to control how far up the fringe goes create a new layer set to darken and do a gradient on that so the fringe fades to solid in a consistent band.
7. Touch up and roughen using dodge and burn tools.

Also, scanned hair for the texture is best but need be you can take a square... create the single pixel selection across, fill with noise and the scale the selection to occupy the full swatch... some wave displacement can help and also duplicating the layer, flipping it and compositing. Use Levels so you get darks and lights but mainly midtone and use Adjust Color/Saturation to colorize the texture... you can do a couple with slightly different hues and then composit to get variation or just painting with color variants using a paint brush set to hue.

I have found, but others disagree, that hair renders well with the texture plugged into both the specular channel and the displacement but at a low value.

Hello !

Thanks for your advise, Momodot !

My transmap no works fine : There are always problems after the render :(

I try again !

Thanks a lot !

Can you show an example? A common problem is the transparent parts still showing a shine... plug the trans map also into the specular to act as a mask. Set both trans and edge trans to 1.0 and fall-off to 0.0. Mybe this will help?
