ZBrush Usage Questions
#1

I am jumping back into Zbrush after being gone in Mudbox since ZB3 hit.

Doing the Helmet Design Tutorial w Joseph Drust tutorial. I will post all questions here as I progress through the tuts whenever something is not clear or the UI does not act as expected.

Question # 1

I am trying to setup the image plane reference views. I have a simple sphere just like Joe does and I load the image and store the front view. Whenever I click it the image and sphere model are as I set them. Now…when I try to change views to the left the sphere is very far away. I have to zoom in quite a bit just to get the sphere close to the same size as the front view I stored. Then I add the image and store the left view.

What I am wondering is why does the sphere zoom out when I switch views? Even when I try to change the sphere size after clicking the front view and then storing the view, hoping this will at least make it a size that isn’t zoomed out, I still end up pressing left view after storing the front view and again the sphere is zoomed out or too small.

Why is this the behavior of switching views? Its as if Zbrush has no relative size within its self.

In Joe’s tut he switches views and does not have to chase his sphere around. I re initialized Zbrush 4R7 in the hopes this zoom would go away and just act like Joe’s does in the tut. To no avail.

Any tips or insight as to why my zbrush does this would be appreciated. Thanks. :slight_smile:

#2

07 Base Dynamesh.

Ok so I noticed that when I used the Dynamesh and that after I tried to update the Dynamesh so I can redistribute the polygons that the symmetry breaks. The X Mirror is off quite a bit. I made a tube protrude out and as soon as I remesh it the right and left side are symmetrical but the x symmetry locaters no longer meet at the midde of the model nor do they touch symmetrical parts anymore.

Is there a reason for this?

20 Hard Surface Details Dynamesh Subtract.

I am trying to use the Insert Sphere brush the same way Joe does with the cylinder.

Only issue is that when I make the sphere as wide as I need it is also as deep. So I switch to the 90 degree angle side view and scale it so it is more flat and shallow only to find out when I return to perspective that it is no longer wide.

I see in the tool tips at the top it says “scale in two axis”. Ok, so this is intended. But, in trying to scale a sphere for cutting I would like to use one scaled as easily as two moves in maya. I can then rotate it for a very shallow cut.

Any tips or key combos to scale the insert sphere in 1 axis?

Thanks :slight_smile:
