Understanding the Make Polymesh 3d process

Hello,

A very basic question about Zbrush. Why does the “Make polymesh 3d” process exist in Zbrush as a specific task available to be done? Why isn’t anything that is in Zbrush automatically a polymesh? For example, the Zbrush primitives- why do they have to be turned in to polymesh 3d objects after you tweek them?

What are these objects before they become polymesh 3d’s?

Thank you.

The ZBrush primitives are shapes based on mathematical formulae. Using the Tool>Initialize settings you can change their shape. Because they are not “fixed” shapes they cannot be sculpted using the sculpting brushes. The Make PolyMesh3D button changes them into a static mesh that can be sculpted.

Thank you, Marcus. I really appreciate it.

I get that, but that all being said, the developers for ZBrush REALLY should just eliminate that Make Polymesh 3D button–especially since it can eviscerate everything else in a scene if you click, “Make Polymesh 3D.”

Default behavior in the program SHOULD be: you made a primitive subtool. It has no alterations done to it by the artist–the program knows it’s a primitive & all default math formulas are true. The artist adjusts ANYTHING on it–it’s now a polymesh 3D. Doesn’t seem like that should be difficult to code. Why does the artist need to do ANYTHING with that?
