I created a head of a creature in ZBrush to show you how to load and append subtools, in this case the eyes. In a tutorial before I explained how to create eyes and polypaint them with ZBrush. Now we will store an eye as subtool and load it for appending to the creature-head.
First load the project in which we created the eye. Then you can save the eye as separate subtool by choosing Save As from the Tools palette into the folder ZTools below your ZBrush installation. The eye is now available as subtool in the lightbox and you can load it in another project.
Create a new project now and sculpt a simple head. I sculpted one that looks like this, but your one doesn’t need to be that detailed:
Just create a simple polymesh with some eyeholes in which you can insert the eyes. Okay, let’s load our eye subtool by opening the Lightbox and selecting the eye that we saved. The eye should appear on the canvas now but we want to see our head again. From the Tool-palette reselect the head-subtool and press Append in the Subtool palette to append the eye like this to the head:
The next thing you have to do is to move the eye to the right position, scale it to the size that fits and rotate it so that the lens‘ direction points a bit to the outside. This can be done with the Move, Size and Rotate-functionality of the Transpose-brush:
After you found the right position for the eye press Duplicate in the Subtool palette, select the duplicated eye, move it to the other eyehole and rotate it 180 degrees:
I hided the head so that you can see the eyes subtools more clearly. This is how the result should look like with the visible head:
After you inserted the eyes you should enable the x-axis symmetry and buildup the mesh around the eyes with the Standard brush or the Clay brush.
As you can see the eyes have a bright shine and the head does not. To achieve this I added another material to the eyes, the Toyplastic material. How this can be done will be a subject of a following tutorial about defining different materials for different subtools.
