ZBrush 3.5 aims to bring you creative freedom and an end to technical constraints. With new features like ZSpheres II, ZSketch, Quick Sketch, Surface Noise, Planar brushes and many other new enhancements, your art will reach a whole new level.

With this new version, we have refined and added to ZBrush's already exceptional toolset, improving the natural traditional media feel that ZBrush is famous for. We've made it easier than ever for you to create organic characters, mechanical objects, environments or product designs. If you are an illustrator, VFX or video game artist, product designer or just a hobbyist passionate about 3D, ZBrush is for you!

We invite you to discover the main new additions to ZBrush 3.5 - enhancements that are the foundation for the upcoming ZBrush 4! In addition, both versions are free upgrades for all registered ZBrush users!

Sketch your mind!

With ZBrush 3.5, create at the speed of light with new sketching features:

QuickSketch allows you to draw your thoughts and ideas in 2D in a simple and elegant way to rough them out so that you can quickly find the best approach and move forward. ZSketch, combined with the improved ZSpheres II, adds the ability to freely create directly in 3D space, sculpting shapes and forms that you could previously only dream of.

In addition, editing your ZSketch is as easy as manipulating a simple skeleton. The variation of poses, forms, and deformations is endless!

Discover a new world with Hard Sculpting

Already popular for its organic capabilities, ZBrush is now opening the door to mechanical sculpting. Create weapons and armor, vehicles or robots, jewelry, product designs... if you can imagine it, there are tools to help you create it!

With features like the new set of brushes (including Trim, Polish and Planar), combined with the new Remesh option to create Boolean-like objects, new Auto Masking functions based on polygroups, improved Lazy Mouse with Backtrack feature, you will be able to make accurate planar surfaces on your models. But these are also free form, following the curves of your imagination.

The combination of these new features enables you to build a near infinite array of brushes, which will perfectly suit all your sculpting needs. To help you get going even faster in your new mechanical world, ZBrush provides several new-dedicated hard-surface brushes by default, or to load at will!
