(This tiny script retains the proportions of a model when subdividing.)
I’m not sure if this has been covered before elsewhere but I figured out a way to use Zbrush’s Cage button to retain the proportions of a low-poly mesh when subdividing. The result is a high-poly mesh which conforms much more closely to the shape of the original low-poly mesh.
Just load the script (Prop_SDiv.TXT) from the Zscript Menu and two buttons will appear in the Zscript window:
1.) Prop.Subdivide (“Press this to retain a model’s proportions when subdividing.”)
2.) Undo (“Undoes last Proportional Subdivide. Use only immediately after Proportionally Subdividing (simply Undoes last four actions).”)
The script is pitifully simple because I have no expertise in creating scripts. After watching the script play a few times you might want to start subdividing in this fashion without the script just to see how and why it works the way it does. Turn off “Show Actions” in the Zscript Menu if you want it to play faster.
