Building a Hand with ZSpheres
From ZBrush Info
by TomLong74 at ZBrushCentral.com
- ZSpheres have the capacity to produce proper topology when used correctly.
- The following are some important features to produce a clean model of a hand.
Key Features:
- ZSpheres connect together by a snap-to-grid system based on the XRes, YRes, & ZRes values.
- ZSpheres' X/Y/Z Res values are located via the Transform palette and appear with an active ZSphere in 3D Edit mode.
- ZSpheres' X/Y/Z Res values are set pre-ZSphere creation.
- XYZAdjust2 (a ZScript by TVEyes) enables post-ZSphere creation X/Y/Z Res editing.
- ZSpheres' X/Y/Z Res values update together.
- [Ctrl]+ dragging an X/Y/Z Res slider changes only that slider's value.
- Typing a value directly into the slider and then [Shift]+[Enter] also changes only that slider's value.
- Move a ZSphere with X/Y/Z Res of 0/0/0 (default Res) into another ZSphere and it will make a dimple.
- Good for eyes, ears, mouth, etc.
- Move a ZSphere with X/Y/Z Res of 1/1/1 (modified Res) into another ZSphere and it will not make a dimple.
- Good for fingers, toes, etc.
The following steps complement the image below.
(A) Start with a default Zsphere.
- Activate 3D Edit mode (hotkey 't').
- Rotate your view straight (rotate while holding Shift).
- Hold down Shift and click on the ZSphere 2 or 3 times. This makes a ZSphere attached to, and the same size as, the original.
(B) Next go to Transform and change the XRes to 3. Notice that the Y&Z also update to 3.
- Hold Shift and change Zres to 2.
- Rotate your view straight.
- Activate Draw mode (hotkey 'q') and attach a ZSphere.
(C) Change Transform:XRes to 1. Notice that the Y&Z values also update to 1.
- Rotate your view straight.
- Activate Draw and attach a ZSphere.
- Activate Move mode (hotkey 'w') and move the newly created ZSphere into the parent ZSphere just to the point that it changes appearence as if concave.
(D) Change Transform:XRes to 0. The Y&Z also update.
- Rotate your view straight.
- Activate Draw, then hold Shift and attach a ZSphere (should appear as a concave ZSphere).
- Attach (with Shift) 2 more times.
Repeat (C) and then (D) three times for each finger. The thumb can be completed with just C & D, D. Adjust the ZSpheres until happy with the result.
