Ztool at 8000X8000

ZBrush Usage Questions
#1

Hello,
I am looking for an efficient way to export my ZBrush illustrations at print resolution. So I raise my document size to 8000X8000, so that I can have my final document antialiased at half of that (4000X4000).
However, when i bring my Ztool into the canvas, I cannot scale it to maximum size possible within the 8000X8000 frame, because:

  1. Zbrush simply does NOT zoom-out to the point where I am able to see the whole canvas
  2. As I scale my Ztool, the canvas begins to zoom in!

I also tried this trick:
step1: I created a 2000X2000 canvas.
step2: I placed my Ztool within this canvas as scaled as possible.
step3: I used the Marker tool to mark my Ztool
step4: I exit edit mode and clear my canvas
step5: I resized my canvas to 8000X8000
step6: I use the marker to bring my Ztool in at the new resolution…BUT
the Ztool is just invizible. I know it is on the canvas because the Zgizmo comes up when I activate Move or Rotate, but the Ztool does not show. I tried to bring it in front by dragging downwards outside the Zgizmo whith Move active, but nothing happens.

Explanations please?
Is there a way to use the 8000X8000 resolution or not?
Alternatives to scaling my model in a high resolution canvas without the canvas zooming in on me?

Thanks for your time.

Keep in mind that ZBrush is using a real-time rendering engine. An 8000x8000 canvas being rendered in real-time is going to tax ANY system.

This document size was mostly made available for those people who wanted to work with 8k textures.

One thing you could try would be to resize your display resolution to the highest your video card will allow. This will hopefully allow you to zoom out far enough that you’ll be able to see the whole canvas. Also, be sure to turn on AA Half while you’re trying to position the model. This will change the displayed canvas to 4000x4000 so that you’ll hopefully be able to get the whole canvas in the frame. Another thing that will help is to close the trays, press Tab to hide the shelf, and turn off the Menus button in the title bar. This will hide as much of the UI as possible so that you have more room to work.

One last thing that I can think of to do would be to program a very simple ZScript that draws and positions the model for you. Then you can just run the ZScript to draw the model on the screen. Because it’s based on mathematics, the ZScript doesn’t have to rely on how much of the canvas is visible. :slight_smile:
