USING CHARACTER CREATOR 3

When using the Remesher InstaLOD check marked, with Unity 3D preset.
I cannot find the Opacity map for things like the hair in Unity.
I have tried telling Unity to use the Diffuse image Alpha as transparency but nothing.
Because the mesh has been combined, I only have the diffuse map and the normal map as main textures.
Where is the Opacity Map? 
it has not been attached to the diffuse map. Even though it is checked.
I am using Genesis 3 Character. Everything used is from Daz3D.(hair,clothing,shoes)

Also used Amplify Shader to create my own material, still cannot get a Alpha from diffuse to use as a mask.
