OK, this is taken from corinthianscori & fivecat’s help notes..
Setting up Genesis:
1) Export Genesis from DAZ Studio using the DAZ Studio obj export option.
2) Save the obj somewhere where you can easily find it since every time ZB has to be restarted it DOES NOT remember the last folder so you have to hunt it down every frigging time. So I created a projects folder on my Desktop and keep that and all the saved PSD’s there until I need to move them to the DAZ Studio Runtime>Textures folder, just keeps things more sane rather than constantly on the hunt for files.
3) Once you have drawn Genesis into the viewport in ZBrush you will need to hit the Edit button and Frame the figure and get it all straightened out by holding down the Shift key and click/drag into the blank area of the viewport, this puts the figure perfectly straight…
4) Turn on the Polyframe and go to the Tools area (right side of UI should be docked there by default, scroll down till you find “Polygroups” expand and click the “Autogroups with UV” and you will see the figures color coded groups appear.
5) Next up is grouping…. Ctrl-Shift-Click (or C+S+C) each body part to hide them (legs, arms, torso, face, zoom in and do this for each ear) You will have the inner mouth, eye parts and nails left (If you don’t want the nails grouped then you will have to C+S+C each (20 more clicks to hide them as well - Personally I do the nails in Photoshop but that’s my choice).
6) Back to the Polygroups palette in the Tools area you will see buttons there “Group Visible” and “Group Masked”. If you prefer not to deal with masking then just use the first button “Group Visible”. If you have masked areas off you can group them using the second button “Group Masked”. This will make it easy to hide things without having to constantly go in and C+S+C all the time.. YUK! I went ahead and redid mine just in case. I have two groups… Inner Mouth and Eye parts as Group 1 and Toe and Finger Nails as Group 2.
NOTE: Don’t forget to switch off the Polyframe (Shift + f) or you will not think your painting anything on the figure!
01) Select Skin Shader and then a skin color that you like
02) Set MRGB
03) Then Color menu, click the “Fill Object” button
04) Increase resolution (Ctrl D) about 2 to 3 times
05) Then set RGB and turn off ZAdd or ZSub buttons
06) Select your paint or material and get to painting.
1) Go to the UV Map palette and set the UV to the size you want to export at (example: 4000X4000)
2) Then to Polypaint menu, make sure Colorize is turned on. It’s on by default so if so leave it be!
3) C+S+C on the parts you want to hide to export you maps. Limbs are arms, legs & nails, Face is just the face, Torso includes the ears!
Once you have all the parts hidden that need to be hidden to export your first map go to Texture Map and click the “New From Polypaint” button (**Note: Map will be flipped, no worries, keep reading**)
4) Next in Texture Map, choose “Clone Texture” button. You will see it appear then to the left side in the Texture palette.
5) Go to the Texture menu (top right of UI) and choose “Flip Vertical” button (It’s icon, second row, second one over)
6) Texture menu click “export” button, name and export. It will ask about saving a “material index” say NO! Continue…
Do this for the other two maps and your done.
Hope that helps everyone understand how easy this can be. Once you get your work flow set up SAVE out your Genesis with the groupings in place as a ZTL file using the Save As button, Right side, top of Tool palette. This way next time you want to do skins for Genesis you will have it already set up and ready to go!
