hey that fibermesh is looking pretty good. may i as did u use the groom brushes with any great effect? as i am having difficulty working with groom brushes?
Nice sculpt and the fibermesh looks great.
thanks guys, I'm going to have a look at convert fibermesh in maya hair now.
I use mostly hairlengthen, hairlong, and groombrush 1. try turning on backface masking for small tweaks.
Also do your hair in patched using different subtools, that way you can control the overall length better, you can see in my first screen shot I have 4 subtools of fibermesh.
If I can get the last step done, I'll do a mini tut for you guys.

heres a screengrab, the import process wasn't too hard, just need to spend time tweaking the hairsysem in maya ( im using vray 2.0 )
will post more details soon when I have the model finished.
In the meantime take a look at these pages, which I used to help
Just thought I'd put a quick update on working with fibermesh curves in Maya.
After a solid day of experimenting with 2 main techniques of exporting curves from fibermesh into maya I got sick of it and rage quited. Messing about with dynamic hair / fur is painfully a slow process, and for what I needed the fur to do didn't justify spending more time on it.
In my opinion doing human hair using the 2 techniques I will describe bellow can be useful, but for fur, which requires more growth control rather then styling the method can be achieved quicker by native fur plugins.
The two main methods I tried for using fibermesh curves to maya was
1 - Curve to maya hair system
2 - Curve to PFX tubes
Method 1 overview - Curve to maya hair system ( full tut here http://mayazest.blogspot.com.au/2012...ay-for_10.html )
- export curves from fibermesh, set your previz amount to 10 - 20 percent if you have a lot of fibers. These will be used as guides to generate hair clumps.
- import it into maya new scene along with the underlaying geometry if you wish
- create a hair system on a dummy geo used PFX and nurbs in rollrout
- select the imported curves ( not group ) and attach it to the hairsystem
- now the fun part starts were you have to start playing with all the settings to get a right look for the hair. if you are doing fur then your clump settings are important as maya basically decides how many strands of hair it will assign to each clump of hair, a clump will be determined by the curves you imported from zbrush ( so more curves you import, the more clumps you will have )
- heres a tip when working on styling, set your simulation to static and display quality to >20 and turn off dynamics and collision, otherwise your computer will blow up if you have imported a lot of curves. your PC will lag no matter what, but doing the above will make it at least useable.
- I've attached some hairsystem presets I used for you to test, these are for maya 2012
Method 2 overview - Curves to PFX tubes ( for non animated things by default, no dynamics or constraints etc )
- The idea of this method is to duplicate the single PFX effect onto the curves from zbrush
- this can be a pretty efficient way of making fur and I think if I spent more time tweaking it might have looked better. But again its a slow process and very cPU and ram intensive.
- import your curves using a higher previz number then above, since this method doesnt do clumps like hairsystem you need to have more curves to cover your obj
- load paint effects ( rendering -> paint effects -> get brush )
- pick a preset thats similar to what you need. ( the bear one is good start ) middle mouse drag from visor into scene
- draw a curve similar length as one of your imported hair curves. you should see some hair, this is what you will use to tweak your PFX preset with. ( template stroke )
- you should select the stroke and edit the settings ( not the shape node settings )
- since we have already styled our hair as strands we dont want any tubes coming out per step. so the important settings are in the "Tubes creation settings"
Tubes per step - 0
Start tubes - <5 ( this is similar to clumps but not as good )
- again tweak tweak tweak ( I've included the presets I test with ) ( dont forget to tweak the colors, shading etc.
Once you think you have a look that could work the next step is to duplicate the PFX stroke onto each of the zbrush curves
((r)) - select the template stroke, paint effects -> get settings from selected stroke ( you will need to do this each time you make a change to the preset )
- select all the imported curves ( not the grp but individual curves )
- paintfx > curve ultilties > attach brush to curve ( sit back relax, this will take a long time...... your PC might crash, if so then you'll have to use less curves or do it in patches)
- what you should end up with is a ****lioad of PFX strokes where your curves used to be.
- you want to group the strokes so you can hide them in the viewport for faster work.
- test render
- if you want to tweak the look of the hair you will need to delete all the strokes and start again from the above steps ((r)), unfortunately theres no quick way around this unless you can script.
To finally achieve a good result I used vrayfur plugin instead, which worked like a charm for the rats fur, I wont go into details on how to do that here but if you want to look I will be putting up a demo on the process on my blog http://www.vfxforge.com/blog/workflo...r-vrayfurmtl3/
Anyway I hope this helps you on the right track, again I think this would work better for long styled hair rather then fur since you are not dealing with so many curves needed for fur )
( PS: I've attached some funny failed attempts and also the vrayfur example and one example with nofur, just basic texturing. )
Using vrayfur and custom maps worked!
No fur textured

Heres my final rat, rigged and fur added using Vrayfur & rendered with Vray for maya.
I wrote a detailed tutorial on my blog on how to do this, hope it helps.
beautiful work on the fur and thanks for you workflow on your website...very useful
Chameleon Study - about 4 hours.
good stuff ! real chamelon hands/fingers are totally diferent yours looks like a frog right now.
