The ZModeler brush is a new brush featuring a set of polygonal modeling functions that will allow for great freedom to take any shape and convert it into everything from an environment to parts for your next IMM brush. This new brush will give you the control to build just about any base mesh or object with as few polygons as possible. With its unique snapping ability you will also now find it even easier than ever to create holes, add edge loops or maybe even create your very own robot.
The workflow is quite simple and is based on two main principles: Target and Action. The ZModeler brush has a smart set of Targets, such as a "Single Polygon", "PolyGroup" or "PolyGroup Border". These Targets remove the need to manually set selections before performing a modeling Action.
As an example, if you wanted to extrude the whole side of a flat model which is comprised of multiple PolyGroups you would first select the Polygon Action Extrude, then select the Flat Island Target. Clicking and dragging any polygon located along the flat side of the model will automatically affect all polygons which are perfectly aligned with the initial polygon.
The ZModeler brush contains most of the common functions found in 3D modeling packages and also has a few smarter ones like the QMesh Action. Not only does this offer you the ability to extrude but also to fuse the extrusion with any adjacent or crossed polygons. Or it can remove blocks of polygons. The QMesh Action will also move pieces of geometry or extract an area to create a new polygonal island. It's versatile and intelligent.Watch QMesh In Action
Because some polygonal modeling actions are repetitive by their very nature, the ZModeler brush stores all settings and values used in your last Action. You can then simply click once on your selection to instantly reproduce that last operation. It works for all ZModeler Actions, saving both time and tedium!Watch Repeat Last In Action
With ZBrush 4R7 comes a new Dynamic Subdivision system. First, let us remind you that traditional subdivision surfaces allow you to preview a more tessellated version of your model while editing at the base mesh level. Dynamic Subdivision provides a powerful alternative. It is comprised of three internal subdivision systems: QuickGrid, Flat Subdivision and Smooth Subdivision. These systems provide you the ability to create real-time bevel effects on your model or simply view a smooth surface aspect. Since it's dynamic, you can swap between or combine modes, even applying changes to the settings or density at any time!
The ZModeler brush contains thousands of Action and Target combinations, putting astonishing power behind something that is so easy to learn and use. With just a little practice, ZModeler and QMesh will undoubtedly become a new favorite in your arsenal for creating low-res geometry assets in ZBrush.
