NanoMesh is a feature of the ZModeler Brush. NanoMesh takes the process of using ZBrush's Insert Mesh and MicroMesh features to a whole new level. The NanoMesh system allows you to populate areas of a model with instanced geometry. These instances can then be modified in real-time to generate different scale, offset and angle for each instance.
NanoMesh also gives you the ability to layer multiple NanoMeshes across the same surface to give even greater variety and creative freedom! With NanoMesh, you can quickly experiment with shape and form as well as add tremendous detail in a few clicks!
