I have Soya hair from skyrim nexus and I have it placed correctly in my data folder. How do I import it into the CK so I can place it on my actor so she has this hair? Don't see anything in the tutoritals about this.

Hair and eyes are now in a different place than they were in Oblivion's Construction Set.

Under Characer/HeadPart you'll see female, male and unisix categories. Underneath each of those you'll see Extra Part and Head Part. New hair can be added under Head Part and the accompanying hairline can be added to Extra Part. You can also add new eyes, eyebrows, etc. here.

Hope that helps.

Okay, I found that. I guess my next question is how to set up the meshes and texture files so that it appears properly. It seems the old dds files do not play well in the new CK.

Yeah, in the Obv CS the hair and eyes textures were applied from WITHIN the editor. Now, they are applied like armor and clothing textures, through the hair nif itself.
