I am somewhat new to ZBrush. When using nanomesh, my IMM pieces sit in the center of the polygons I’m putting them on. Is there a way to get them to sit on top of the polys??
Here is what I get: 
When making this IMM brush, I looked at them facing the pointy end so they’d come out standing up. This is basically the goal I have in mind (made this manually) : 
Please and thank you! 
Hello @Altarior
To control the height the nano is drawn at, adjust the Brush > Depth> Imbed value.
To adjust the height from poly after drawn out, adjust the Tool> Nanomesh> ZOffset
Good luck! 
Hi @Altarior Welcome to ZBrush Central!
When creating IMM brushes, it’s a good idea to Unify all the subtools before making the brush.
With the top subtool selected, go to “Tool > Deformation” and click “Unify”. Then at the bottom of the Deformation subpalette, click “Apply To Other” to unify the remaining subtools. Then click “Create InsertMultiMesh” in the brush palette.
Also applies to “Create InsertMesh”.
