GUIDE SNAP
  1. This tool has two main functions: For Daz Studio workflow where the creation of hair does not originate from Maya Xgen and the guides need to be snapped to tubes/cards or curves.
  2. Merging curves that goes into a French braid style hair.
  3. You can now use a ramp to control the tip/root snapping strength.

Merge Side Curves into a French Braid
  1. Use the Curve To Braids Tool to create center curves.
  2. NOTE: The 'first CV' of Maya curve need to be "sitting on" or "through" the scalp geo, it can not be floating in 3D space.
  3. Select a guide, and shift select a Maya curve and click Snap Guide.
  4. Remove excess points and sculpt the guide better to fit with the hair flow.
  5. Please be noted that using Undo (Ctrl + Z) will not work due to nature of XGen.
You can also snap a guide to another guide. 
Using The Ramp Control
Starting from version V.13.04, you ​will be able to use a ramp to control the tip/root snap strength.
  • When the ramp value is all the way up, it's the 'full' snapping strength. Here we are snapping just the tip of an XGen guide to a Maya curve with a fall off (Tip:1.0, Root:0.0).
  • When the ramp value is half way up, it uses half of the snapping strength.
Daz Studio Guides Snap to Curves
​As the snapping is still based on Maya curves, you will need to convert all the tubes/cards into Maya curves first.
If the geometries are tubes, make sure Extract From is set to “Tubes”. 
​Set to “Cards” if they come in as cards.
Then select all the tubes/cards (NOT the groups), and click on the ‘Create Center Curve’ button. This will create a curve in the ‘center’ of each tube/card. Please note, this will create a ‘xgt_guideSnap_curves’ group and the extracted curve(s) will be put under it.
To snap single guide to curve, select the guide first, and shift select the a curve,  then click “Snap Guide”.
To batch snap, select the Xgen description node (Or the subdPatch node), and shift select the curve ‘group’ (‘xgt_guideSnap_curves’ ).
Click ‘Batch Snap Guide’.
