FREE: Decorative IMM Brush Set for ZBrush
This brush contains 28 unique IMM (insert multi mesh) curves and 14 unique objects that can be added to your ZBrush sculpts.
NOTE: Some of the 14 unique objects are a bit more high res by default. There are also three duplicate curves which I could not remove (I did not count those).
Extract to <Programs>/<ZBrush folder>/ZStartup/BrushPresets to make the brushes load with each launch of ZBrush
