What’s new in ZBrushCore 2018

Alpha 3D with Chisel Brushes

ZBrushCore 2018 introduces two new brushes: Chisel3D and ChiselCreature brushes. These Vector Displacement Mesh (or VDM) brushes allow you to sculpt with a 3D Alpha which will support overhangs or draw complex objects on the surface with a single brush stroke. Imagine being able to texture a dragon with overlapping scales or draw a fully formed ear without needing to re-sculpt it for every model.

These brushes are affected by the density of the polygons needed to reproduce the brush’s shape. If you are working with a low-resolution mesh, your model may not have enough polygons to deform and flawlessly rebuild the shape stored in the brush.

Gizmo3D Deformers and Primitives

The latest version of ZBrushCore introduces a selection of six Gizmo3D Deformers. Each deformer has a unique feature set to allow quick shape alterations that would not be possible through brush strokes.

The Gizmo 3D now also includes the eight polygonal primitives which are intended to be quickly inserted in the current SubTool. These parametric meshes can have their topology modified on the fly at insertion time, before being manipulated and transformed by the Gizmo 3D.

Text 3D and Vector Shapes

Using 3D text shapes or designs based on logos can be very useful when creating models. ZBrushCore provides a full 3D text creator plugin that makes use of all fonts available on your machine. The tool provides stylistic modifications like extrusions, bevels and even right to left orientation.

Because 3D text is vector based, the tool is also able to import vector files in SVG format, allowing you to convert logos or other vector images to 3D shapes.

The 3D Text and Shape Creator tool is located in the ZPlugins palette. Please read the Text 3D and Vector Shapes plugin documentation found in the online documentation (available only in English).

3D Printing

ZBrushCore includes 3D Print Hub: a dedicated plugin for 3D printing as well as importing STL. Found in the ZPlugins palette, it will allow you to export with multiple options, including scale and units for 3D printing purposes.

After exporting your file (usually an STL), you will be able to upload it online to 3D printing providers or use the slicing software of your choice to print your creations.

Polygon Count Optimization

Although ZBrushCore has no trouble handling models with millions of polygons, most other applications cannot. When exporting a 3D model to another application (especially for 3D printing) it can be useful to reduce its number of polygons. However, when doing this you naturally want to maintain the quality of the model’s details.

The Decimation Master presets

Located in the ZPlugins palette, Decimation Master provides several preset values (in thousands of polygons). These will automatically reduce the polygon count while also analyzing the surface to intelligently remove polygons based upon surface details, with more being removed from regions that have less detail. As an example, if your model has approximately 5 million polygons you can click the 150k preset to target that polygon count without noticeably affecting the appearance of the model. You can even try again by clicking another preset to find which value best suits your needs.


Note: You can freely press the different presets in any order to change the value of the polygon count. However, doing anything to affect the model structure – such as applying a brush stroke or any other type of change – will lock in the current decimation results, eliminating the ability to return to a higher count preset. Once you have edited the model, pressing any preset button would use the new/current state model as the starting point of the optimization.
