A greeble or nurnie is a small piece of detailing added to break up the surface of an object to add visual interest to a surface or object, particularly in movie special effects. They serve no real purpose other than to add complexity to the object, and cause the flow of the eye over the surface of the object to be interrupted, usually giving the impression of increased size. It is essentially the small detailed technical part of a larger object. The detail can be made from geometric primitives, including cylinders, cubes, and rectangles, combined to create intricate, but meaningless, surface detail. Greebles are commonly found on models or drawings of fictional spacecraft in science fiction

Adding detail to 3D objects for enhancement of apparent size or realism is a time-consuming task. It is made easier if tools are available to reduce the workload and time involved. Greebler is that new tool for your arsenal. It provides support for multiprocessors, NET Render, selections, materials, and much more.

By adding models under the Greebler generator object you get instant results that can be tweaked and retweaked until you are satisfied. The models’ surfaces are extruded and populated with shapes to add realism and dimension without exacting work. You can control the density and coverage of the added details as well as a number of other parameters. And if you don’t want to cover the entire model in details or want different details for different surface areas, you can use Greebler tags in conjunction with Polygon Selection tags to specify where you want details, where you do not, and what kind of details for that area.

On top of the typical choices found in most greebling software to enhance your work, there is also the ability to expand your arsenal with custom greeble shapes and objects. Objects can be duplicated across the surface as Instances or Render Instances allowing a rich amount of surface detailing while saving memory and time.
