006 Dynamesh Groups
Michael Pavlovich
Overview
This video demonstrates various techniques for separating a 3D model into distinct polygroups and subtools within ZBrush, primarily using Dynamesh and masking features. The presenter begins by showing how to manually sculpt details without splitting the model, then moves on to using the 'Slice Curve' tool to divide the model along specific lines, such as the sock line. A key feature highlighted is Dynamesh with the 'Groups' option enabled, which automatically separates the model into new subtools based on existing polygroups. The video also covers the importance of poly paint and how it can be lost if Dynamesh is applied with poly paint turned off. Finally, it explores masking techniques to isolate specific areas, convert them into polygroups, and then separate them into independent subtools for further manipulation, such as inflating or sculpting the pants separately from the body.

Chapters
- •Manual sculpting is possible without dividing the model.
- •Use the Standard brush with ZAdd and the ALT key for sculpting.
- •LazyMouse (L) can provide more controlled sculpting lines.
- •Adjust LazyRadius in the Stroke menu for finer control.
- •Models can be split into separate parts for better control.
- •Use 'Slice Curve' (Ctrl+Shift) to draw division lines on the model.
- •Transparent mode helps visualize slicing through the mesh.
- •Slicing creates new polygroups, visible in Polyframe mode.
- •Dynamesh options include a 'Groups' setting.
- •Enabling 'Groups' during Dynamesh separates the model based on polygroups.
- •This creates separate, self-contained pieces, not full subtools initially.
- •Use Ctrl+Shift+Click to select and isolate these separated pieces.
- •After Dynamesh with Groups, separated pieces can be extracted.
- •Ctrl+Shift+A (Grow All) selects the entire connected polygroup.
- •This allows for isolating and working on specific parts like the feet or body sections.
- •Ensure poly paint is preserved by having it on when Dynameshing.
- •Masking is an alternative method to create polygroups.
- •Use Mask Lasso (Ctrl+Mask Lasso) to select an area.
- •Mask Pin or other masking tools can refine the mask boundaries.
- •Ctrl+W converts the masked area into a new polygroup.
- •Once a polygroup is created from a mask, Dynamesh with Groups can separate it.
- •Alternatively, specific polygroups can be split into separate subtools.
- •Masking allows for precise isolation of areas like clothing (e.g., pants).
- •Separated parts can then be manipulated independently (e.g., inflating pants).
Key Takeaways
- 1ZBrush offers multiple methods for separating model parts, including manual slicing and masking.
- 2Dynamesh with the 'Groups' option is a powerful tool for automatically splitting a model based on its polygroups.
- 3Be mindful of poly paint; it can be lost if Dynamesh is applied with poly paint turned off.
- 4Masking techniques (Mask Lasso, Mask Pin) are essential for precisely defining areas to become new polygroups.
- 5Ctrl+W is the shortcut to create a new polygroup from a masked area.
- 6Separated polygroups can be easily extracted into their own subtools for independent editing.
- 7The 'Grow All' function (Ctrl+Shift+A) is useful for selecting entire connected polygroups.
- 8Precise control over model components allows for more detailed and efficient sculpting workflows.
