Alpha channel set up?
using an image plane to texture an eyebrow, I've for an alphachannel that matches to hairs exactly.
Tried saving as a tiff a and a targa, which automatically assigns the file to transparency. This didn't work, tried in the connection editor to manually assign the out alpha to the transparency r, g and b. This didn't work either.
Tried inverting the alpha channel in photoshop, since I wasn't sure it maya read white or black as transparent. This didn't work either.
anyone know what's happening?
thanks,
gubar

Still got a problem; though it is transparent, when I layer them, I can still see the background, but I can't see the layer under it (was going to have layers of hair for the brows and the head hair, this is just a very rough test of the technique).
I've tried setting mental ray's trace depth higher, but still I can't see the underneath layer's colour.
again, any help would be great.
thanks,
gubar
