I've imported hair from daz3d into zbrush then to maya. How do I now convert this object into ornatrix hair?

And re-rooting the hairs so that that are growing from the correct source.

Hi Julian,

Assuming you are importing mesh/polygon strips, you can convert them to hair using the HairFromMeshStrips operator, then you can convert the hair into guides using the GuidesFromHair operator, and finnaly ground to guides to the head or scalp mesh using the GroundStrands operator.

May I send a file to you to examine?

Yes, you can send it to: Jeordanis.f@ephere.com.

Did you receive the link?

Hello there,

Yes, I have your scene, I'll get back to you soon.

After taking a look into your files, I suggest the same approach as before:

  • Use HairFromMeshStrips to convert the poligons into hair,
  • Convert the hair into guides using the GuidesFromHair operator,
  • Ground to guides to the head or scalp mesh using the GroundStrands operator.

 

You should extract part of the mesh of the head to use a scalp/distribution/growth mesh and then ground the guides to that mesh as described in step three. There is a lot of poligon hairs so you might have to rotate some of them manually using MeshStripEditing Tool found inside HairFromMeshStrips, select one of the arrows and click the Rotate Strips button inside HairFromMeshStrips.

More information about HairFromMesh Strips can be found in our documentation HERE, three video tutorials are included in the same page. I hope this can help you.

To deal with the amount of hair mesh strips of the Afro example (or any of them), what should the minimum hardware setup be? In other words, should the high hair count of the afro slow the conversion performance? Or what would make the performance better on big, long hair lots of hair?

Yes, the amount of polygons will affect the speed of the conversion, but it took me only a few seconds to convert the Straight_Hair example into Ornatrix hair.

The Afro example have a higher polycount but you can convert the hair in segments: Divide the afro hair in two or four parts and convert one of them, then add the rest to the same hair object using the "Add Strip Mesh" button inside HairFromMeshStrips. This will reduce the time of conversion.
