Introduction to Zbrush Digital Tutors

Subdividing Geometry

– Subdivision tools are found under Tool > Geometry.

– Tool > Geometry > Divide or Ctrl + D adds one subdivision layer to the active tool.

– Move up one subdivision layer using D or move down one subdivision layer using Shift + D. You can also use the SDiv slider or the Higher Res / Lower Res buttons.

Use the divide button to add subdivision layers that can be moved between using the slider or buttons.

– use the Del Lower / Del Higher to delete subdivision layers. The layers are relative to the current layer.

– Tool > Geometry > Smt smooths the mesh when subdivision layers are added. If this option is turned off polygons are added but the shape of the mesh is not changed.

Turning the Smt modifier off when subdividing adds polygons without changing the shape of the mesh.

– if the first subdivision layers are added without Smt, then the top layer is added with Smt some smoothing will be added to lower subdivision layers.

– Ztools retain their subdivision layers.

– Low Subdivision models are needed for creating Normal Maps from High Subdivision models.

– Tool > Geometry > Freeze Subdivision Levels can be used to retain subdivision information when carrying out operations that normally need a mesh with no subdivision levels.
