in Daz Studio Discussion

hey guys!

i have tried as hard as i could to try and export the fibermesh from ZBrush 4R7 P3 into the Daz studio, i just can't figure out how!

i am trying to give the Genesis model a custom haircut and custom body hair.

i would really appreciate any help or a small tutorial that could show how it could be done!

Thank you so much.

    DAZ Studio

    1 - select object

    2 - Press GoZ

    Zbrush

    3 - use masks to mark areas for fiber hair

    4 - create Zbrush fiber hair preview

    5 - change parameters of Zbrush fiber hair preview to get the look you want

    6 - Confirm the fiber preview hair curves to be converted into actual fiber mesh geometry

    7 - use brushes to comb the hair geometry into position

    8 - in the subtool menu select the fiber hair

    9 - click GoZ

    - - -

    DAZ Studio

    10 - import dialogue add fiber hair as new object

    11 - save scene

     

    - - -

    At which exact step have you been struggeling?

    In any case make sure to watch all the fiber mesh related videos in the ZClassroom:

    https://pixologic.com/zclassroom/workshop/fibermesh

    and the basic GoZ tutorial video for DAZ Studio

    Follow up:

    If you want to create hair for different areas like body and head you can either

    - export the fiber hair with GoZ one after the other by selecting one fiber mesh subtool, GoZ, select next fiber mesh hair subtool, GoZ

    or

    - merge all the fiber hair subtools before exporting with GoZ

    - - -

    This image is an example how multiple fiber mesh hair layers were added together:

     

    After GoZ from Zbrush to DAZ Studio the first layer of hair did not seem thick enough.

    I could now just have restarted from scratch.

    Instead I choose to actually make a second layer of fiber mesh hair and combine it with the first.

    In addition there are addtional layers of hair for the ears, chin, brow area with different lenghts.

    - - -

    The final coloring of the hair was done in the OctaneRender Node Graph Editor. Experiment with some turbulence, noise or any other fractal nodes to create random patterns.

    And last but not least:

    If you do not show the whole object in the final render only create fiber mesh hair for those areas that are actually visible to save valuable space in system RAM and VRAM.

    I have the Zbrush tool selected and hit GoZ, and instead of placing the object in DAZ 3D 4.9 which was open, it instead opened up an older DAZ 4.6 (MAC IOS), which is not what I wanted.  I closed DAZ 4.6, deleted the application, went back into Zbrush, hit the GoZ button again, but now, nothing happens.  How do I get Zbrush to point ot ht e latest version of Daz3D

    I created a new thread for updating to ZBrush 4R8.

    The steps described there hopefully help you to solve your issue as well.

    Do you know a good tutorial to create hair with fibermesh for genesis ?

  • WendyLuvsCatzWendyLuvsCatz Posts: 38,512

    I would love to know how to UV map the hair to match the underlying tool (model) it was grown on, fiber mapping vertically maps each shaft in overlapping UV's great for head hairs not for animal furs.

    - Specifically for Genesis: No.

    - Fiber hair tutorials from the official ZClassroom:

     I would love to know how to UV map the hair to match the underlying tool (model) it was grown on, fiber mapping vertically maps each shaft in overlapping UV's great for head hairs not for animal furs.

    Very good question. So far I worked around that challenge.

    So the short answer is: I do not know.

    - - -

    What I can share is how I worked around it:

     

    Custom Fiber Hair Shader for Octane

    I created custom hair shaders for fiber mesh hair in the Node Graph Editor for OctaneRender.

    ->  Experiment with some turbulence, noise or any other fractal nodes to create random patterns.

    -> Experiment with  "projection" modes and UVW transforms

     

    Basically projection modes work live different UV wrapping modes. The difference is that you can change the projection after the texture was created.

    In addition to just UV there is also the third W axis -> UVW

    You take a texture with an existing UV and "project" it on the surface similar like a different "UV wrapping" mode.

    - Switch between 2D UV and 3D UVW projection modes

    - Switch beteen object and world space

    - In addition use nodes like scaling, tiling etc.

    - - -

    Custom Fiber Hair Shader for Iray

    You might be able to create a custom hair shader for fiber mesh in Iray.

    With "custom" I mean that you create you own shader with MDL (Material Definition Language) nodes in the DS Shader Mixer.

    Unfortunately I do not know of any user friendly tutorials about the DS Shader Mixer and the MDL bricks.

    I still hope for an updated DS node graph solution optimized for Nvidia Iray.

    3rd party apps

    Some older 3rd party forum posts talk about 3rd party apps that can generate colored textures for ZBrush fiber mesh hair based on the body texture.

    I have not found an app yet. Links outdated or misspelled.

    - - -

    "Look at my Hair"

    When you create Fiber mesh hair as a separate obj geometry with "Look at my Hair" a set of additional textures is created which seem to use the body texture to color the generated fiber mesh hair.

    - Apply the body texture to the original object.

    - Apply the fiber mesh textures to the fiber mesh groups.

    - - -

     

    The three left ones are fiber mesh hair textures

    The one on the right is the body texture.

    - - -

    -> Try asking the "Look at my Hair" developers how they solved the challenge and generated the colored fiber mesh textures...

    - - -

    -> Does anyone else have the answers?

    well I sort of solved my issue at least

    if I use the packed UV option I can save a textured pelt I paint with polypaint or coloured using Zprojection from an image

     

    I did this Squirrel prop, video, very fast low quality iray render

    it maps like this

    Could you describe how you did this, Wendy? Many thanks!
