Zbrush FiberMesh Bake with xNormal
polycounter lvl 6
I decided to do a little test to see what would happen baking the Zbrush FiberMesh.
all maps 512x512 AO bucket size 64 to be fast.
baked the zbrush polypaint. the good part is that we can paint the fibermesh
the low poly part is in max viewport

seems your loosing some of the effect too noise.
Good stuff. :thumbup:
I find normal mapping hair on a per-strand basis always looks a bit crap regardless of technique though so it's not a weakness in the process - i've always found it better to work on clumps and leave the specular and diffuse to pick out strands
Your AO and diffuse came out nice so this is definitely a workable technique and since you can get the shapes you want out of fibermesh ten times faster than using max hair i'd call it a win
only the normal comes out "weird" but i believe with some configuration is possible to have a good result
@Bonebrew22 Everything can be configured, width, thickness, twist, quantity, distribution, base color, mid color, top color....
Now another thing that has much potential to generate maps is Micromesh

Would Micromesh generate maps though / be exported? I haven't played around with it, but it reads more like something that only occurs during BPR.
you're right, there is no way to export the Micromesh
maybe some plugin
I think using micromesh would be easy to do something like hauberk creating a tiled micromesh
Seems that it's more realistic a hand sculpt of furs or using a photosurce?
what's the problem with the normal maps?
keep us updated
Here's a quick test with thicker fibres, rendered with BPR and then Zapplinked to the diffuse. I didn't spend too much time grooming as evidence by that terrible clusterfff near the mouth, and I used the default light which lead to baking in shadows behind and under the head. Perhaps with some more time spent, it could have some potential for certain uses.
I imagine you could do the same thing to some simpler planes, which would also let you bake in the edges of the strands for an alpha (flatcolor black on white document, or vice versa). I'm not sure how that would compete against just doing it in photoshop.
1. Give the mesh a texture. Create a new blank one if you must.
2. Do your BPR Render and save it. It's optional, but you might want to store the camera position in case you accidentally move it.
3. Drop with Projection Master and Zapplink it to Photoshop
4. Load the BPR Render in Photoshop and save it
5. Send it back to Zbrush and pick it up. The result should be transfered to the texture instead of polypaint.
I used Xnormal to bake.
Basically you need to transform the fibermesh into a 3D mesh (Polymesh3D)
Exports the high poly OBJ
(you can paint the model/fiber with polypaint and export, the polypaint information will be embedded inside the OBJ file *this is just vertex paint* xnormal also read this info to make texture projection)
Inside xnormal load your High and Low poly models to bake everything (The low poly model needs to have UVs)
Bake
This will works best with thicker fiber, extremely thin fibers can make the normal map jagged
Would you be kind enough to share your process of transferring the fibermesh to UV's to your lowpoly head. I'm new to zbrush and i'm having a hard time converting fibermesh fur into a texture.
Any help would be greatly appreciated.

the low poly result looks stylised to me . maybe some black lines here and there and bam ( the walking dead style )
also look at your ram consumption, xnormal is 64bit, zbrush is not.
