"pixol" contains information on X and Y position and color values. Additionally, it contains information on depth (or Z position), orientation and material. ZBrush-related files store pixol information, but when these maps are exported (e.g., to JPEG or PNG formats) they are flattened and the pixol data is lost. This technique is similar in concept to a voxel, another kind of 3D pixel. Features ZBrush comes with many features to aid in the sculpting of models and meshes. 3D Brushes The initial ZBrush download comes with thirty 3D sculpting brushes with more available for download. Each brush offers unique attributes as well as allowing general control over hardness, intensity, and size. Alphas, used to create a specific pattern or shape, and textures are also editable brush features. Polypaint Polypainting allows users to paint on an object's surface without the need to first assign a texture map by adding color directly to the polygons. Illustration ZBrush also gives the ability to sculpt in 2.5D and comes with several brushes for that purpose. A pixol put down when sculpting or illustrating in 2.5D contains information on its own color, depth, material, position and lighting information. Transpose ZBrush also has a feature that is similar to skeletal animation in other 3D programs. The transpose feature allows a user to isolate a part of the model and pose it without the need of skeletal rigging. ZSpheres A user can create a base mesh with uniform topology and then convert it into a sculptable model by starting out with a simple sphere and extracting more "ZSpheres", until the basic shape of the desired model is created. GoZ Introduced in ZBrush 3.2 OS X, GoZ automates setting up shading networks for normal, displacement, and texture maps of the 3D models in GoZ-enabled applications. Upon sending the mesh back to ZBrush, GoZ will automatically remap the existing high-resolution details to the incoming mesh. GoZ will take care of operations such as correcting points & polygons order. The updated mesh is immediately ready for further detailing, map extractions, and transferring to any other GoZ-enabled application. Best Preview Render Also included is a full render suite known as Best Preview Render, which allows use of full 360° environment maps to light scenes using HDRI images. BPR includes a new light manipulation system called LightCaps. With it, one can not only adjust how the lights in the scene are placed
