How can I Make Material borders Transparent ??

Hello there. I've got a question. I use custom models ( not smart contents from Daz Store ). Almost all models need border transparency on hair textures. But when I render the scene , it turns white instead of transparent !! Example :

Looks like you'ew missing a black/white texyure map in cutout oppacity (if you're using Iray)

We would need more information n what you are doing - at the very least, a screen shot showing the Surface settings.

More information is good. :) My gut feeling is that you may be using a PNG file or something and expecting the Alpha channel in the texture file to handle the transparency. But neither Iray nor 3Delight work that way. They both expect a grayscale image in either the Cutout Opactiy (Iray) or Opacity Strength (3Delight) channel. Black is completely invisible, white is completely visible with the gray shades between providing partial opacity.
