IClone character hair issue
Hi!
I'h having issues at importing an IClone character into Unity using an fbx export from 3dxchange. I know this topic has been discussed several times, but none of the answers I found were able to solve my issue. So moving on to the problem. After importing a character from IClone, the eyes, lashes and hair are messed up. Previously I've used Genesis 3 from daz3D and I've experienced the same issues. Thus far I managed to solve the lashes and eyes, but the hair is still a mystery. Below you can see a picture of the issue (the scalp is visible through the hair and the hair is slightly transparent). 
From what I read by now, it's due to the materials opacity getting messed up after importing it to unity and using unity's standard shader.
Can someone please give me a slightly in depth explanation or tutorial on how to fix this issue? I've been struggling with it and ignoring it for a few weeks now, but at this point it's really important.
Edit: I added a picture of the settings I use for the hair. 
This is a Z-Order issue with the shaders. They are of the same priority in the hair materials so they fight each other in order to render.
You can fix this issue by changing the render order. Click on the material in question, and in the inspector window, right click the tab at the top and click Debug.
You can then specify the render order. Higher is first, down to lowest. So for hair, mark the most visible parts with high priority. Set the scalp as the lowest priority.
I had this issue with Daz characters and this usually fixes the problem.
Hi @cgarossi ! Thank you for your answer! I'm not sure if I completely understood how to change the render priority. I used the Custom Render Queue option and increased it on the hair, and also reduced it on the scalp to 0. This reduced the weirdness of it by a bit but the hair is still transparent. I edited my question by adding a few pictures of the settings for the hair. Can you tell me if I did it right or any other ideas would be greatly praised!
I can't see your edit for some reason.
Have you tried using double sided shaders? It's possible the hair normals are single direction (as they are normally) so the back of the mesh is not rendering. If you visit the asset store you can download $$anonymous$$orph3D Lite models for free which come with a set of double sided shaders. Try those out first.
If you still get issues, export the hair mesh separately and split the mesh up by material in blender then parent it to an empty. I do this with Daz3D hair. Export the model then in blender split the hair mesh by material then unsubdivide by 1 to reduce the poly count (this doesn't break the UV). When you reimport into Unity you then have more control over how the hair geometry renders. Unity 5.5 adds the ability to prioritise by geometry Z order, which solves most issues. You can access this via the material debug menu.

Wanted to share a CC3 hair demo from the Virtuoso HDRP Hair Shader.
The shader uses a combination of a VCC_LitAlpha base, VCC_Hair for the main hair strands. To provide the thickness effect it eliminates the transparency issues using a custom hair cap rig with an applied alpha brush touch up such that it conforms to the hair style. The alpha brush allow for direct touch ups in the unity editor using the VCC Character Creator product.
Here it shows the hair shader operating with a transparent object behind it. It works find with shader sorting priorities.
