Scaling in Zbrush with subdivisions and layers

ZBrush Usage Questions
#1

Scaling in Zbrush is always problematic when there are subdivisions and layers, these are some of my experiences with different methods of scaling. Each one with his own problems and none free of them. It would be cool to know if somebody has extra info or workaround:

Deformation scale


  • Layer in recording
    • [LIST]
  • Size change is stored in the recording layer

  • Layer not recording

    • DONT USE: Acts wrong as the scale disappear as soon you deactivate or interact with other layers

  • The detail IS LOST if the scale is done in the lower subdivision
  • The detail IS NOT LOST if the scale is done in the higher subdivision
  • This will happen even all layers are on or off or the model has layers or not.
  • If the model has no layer and has frozen subdivision will become the worse scenario when unfrozen, smoother than ever and with artifacts.

    • As above

    Transpose scale


    • As above

    Transpose master scale


    • Layer recording or not: Identical to above
    • Model is forced to lower subdivision. This means
    • The detail IS LOST as the scale is done in the lower subdivision in a less extreme way than above. But enough to mess the model.
    • In general never use transpose master to scale models unless you don’t care about details or the model has not subdivisions.

    Tool-export scale


    • Using copy paste to another tool, change the tool-export values and return the subtool to the original tool
    • Layer recording or not: Identical to above
    • There is NOT LOST of detail if this is done in the lower subdivision or higher

    ZsceneManager merging temporally subtools


    • Layer in recording
      • [LIST]
    • Size change is stored in the recording layer

  • Layer not recording

    • DONT USE: Acts wrong as the scale disappear as soon you deactivate or interact with other layers

  • The detail IS LOST IN A SUBTLE WAY if the scale is done in the lower subdivision. Pores and details of that scale will lose 50% of strength.
  • The detail IS NOT LOST if the scale is done in the higher subdivision
  • This system is the only one that allows change several subtools at same time without affecting detail, as long all are in the higher subdivision as uses a different system than transpose master. Also allows objects with different subdivisions levels without losing subdivisions. But in the current version loses the UVs.

    It’s 2022 and there’s still no way to scale subtools with subdivs without losing details?
