Duplicated SubTool gets moved randomly in space

ZBrush Usage Questions

Hello everyone! Glad to find this place! :smiley:

I’m new to ZBrush and I’m trying to educate myself. I have been following a Helmet Design course in ZClassroom: http://pixologic.com/zclassroom/workshop/helmet-design
But got myself stuck in a “Duplicate” issue… basically my duplicated SubTool just cannot hold the same position as the original SubTool does. I don’t know what happened…

Let me explain some details about my question…

First there was a human model named “PM3D_defalt1_2”. He was the guy I wanted to put a helmet on. This man model was a course file I downloaded from zclassroom site. I imported it into ZBrush using Zplugin>3D Print Exporter>STL Import

The egg shaped mesh (PM3D_Sphere304) in the first screenshot above was the original helmet base mesh I created (I used Insert SubTool>Sphere3D, and then used Move Brush to change the shape and sort of move its position to match the human model. I intentionally avoided using Transpose “Move” since I thought it might make my mesh off symmetry?)

Before I moved to the next stage that would break my basic helmet mesh into pieces, I wanted to save a duplicated mesh of it just in case. The semi transparent “PM3D_Sphere303” appears in the second screenshot is the dupe. I used Tool Pallet>SubTool>Duplicate button to duplicate it from my original helmet base mesh.

As you can see somehow the copy got moved below the “Floor” of my original mesh and the human model. I didn’t move it. It moved itself right after I clicked that “Duplicate” button in the SubTool Panel. And that’s the question I’ve got - the duplicate couldn’t keep the same position as the original SubTool has. It seemed to reset its “Floor” and thus got shift in space randomly. I don’t know what cause this to happen? And how to fix it?

I’ve been googling it but couldn’t find the answer. I hope someone here can kindly give me some advice…

Whoever you are, thank you very much in advance. Would really appreciate!! :slight_smile:

Update:

I still don’t know what had happened, but I figured out how to fix it.

Since I noticed that if I duplicate the first copy (not the original mesh), the 2nd copy (the duplicate of the 1st duplicate) won’t move in space. So I just deleted the original mesh and I’m gonna use the 1st duplicate as a new original mesh for future duplication.
As simple as that.

Having returned to using ZBrush after a while, I’m also encountering this issue.

Performing an Undo brings the duplicated subtool back to the original subtool’s position and scale.

Maybe the subtool shift and scale is not an issue but intentional behaviour to show there’s a copy in the scene?

I’d prefer to have a duplicated subtool just keep the same position and scale, as it used to be.

:point_right: Edit: Hmm… :thinking: Somehow I can’t reproduce the mentioned issue anymore. Maybe it was a mangled RAM issue during a particular session. :confused:
