Changing Color Floods Object?

ZBrush Usage Questions
#1

Maybe I am just doing it all wrong or something fundamental I don’t understand. Just getting my head around Zbrush.

This is what I do:

Create A Sphere.
Go into edit mode. Make it a poly object and divide.
Make sure rgb is on and Mrgb/Zsub/App are off.

Change the color to begin painting on the material.

It fills the object. OK fine I change it back. Fills the object. This can go on forever.

Finally I realize, If I start painting, just a stroke, it stops doing this and I can start panting on the mesh.

OK. So of course then I remember a tutorial where he fills the object first before painting. OK fine. I get it now. That also stops this ping pong.

Also when I then draw out another object out of Edit Mode it takes on the current color.

Why is that swatch tied into auto flooding the object all the time? Is there something fundamental going on here I need to get my head around? Does this mean when you are painting you are creating a map or something “under the hood” and that otherwise the canvas is open to color? Something like that?

The way I see it. Polypaint is equivalent to vertex painting, filling an object with the colour gives the vertices a starting colour which you can then add further colour/material onto when you continue to polypaint

If a model has no polypaint data (m and rgb), then it will simply use whatever color and material are currently active. Once you give the model polypaint (either by filling with a color or simply by turning polypaint on), then the model will display the polypaint data instead of the active color.

OK. I see. Thanks guys.

It also automatically turns poly paint on “Colorize” in the tool palette when you start painting. I had not noticed that before, nor had I read that part of the manual yet. Just got to it now. Makes sense.

Thanks! :slight_smile:
