Summary of ZBrush Character Creation: Advanced Digital Sculpting

Amazon Exclusive: Scott Spencer's Favorite ZBrush Tricks

1. Move your light often. When sculpting try and use the basic material instead of the matcap shaders. The basic material allows you to interactively light the surface as you work. This makes judging your forms much easier since you can see shadows moving across the surface.

2. Use specular highlights. When working make sure you have some level of specular shine on the surface material. Specular highlights allows you to easily see the high points of the sculpt as well as pick out the fine details of the surface texture.

3. Store morph targets. When adding high frequency details it is a good habit to store a morph target of the model with no high frequency details. This will allow you to use the morph brush as a kind of "detail eraser", blending out the skin texture partially or completely as you work.

4. Use custom alphas. While ZBrush has many wonderful alphas preinstalled, get in the habit of finding useful images and storing them as your personal alpha library. You can quickly build up an in-depth and original collection of skin textures. Not only will this help you avoid clichéd alphas, it will also help you learn about the various kinds of wrinkle and scale patterns in nature by looking at the reference you collect.

5. Create and use custom menus.Use the custom menu options under preferences to group your most used buttons and options in one personal menu. This menu can then be mapped with a hotkey and called up at the touch of a button from anywhere in the user interface. This is an incredibly useful tool for speeding up your working time.

6. Create and use hotkeys. Another method to increase speed is using hotkeys. ZBrush has default hotkeys which can be found in the tool tip when hovering over a menu option. You can change these keys and set new hotkeys by pressing control and clicking on a menu option. ZBrush will the ask you to press the key combination you wish to assign as a hotkey.

7. Combine extraneous subtools. Your subtool menu can quickly become cluttered with extraneous parts. Two separate eyeballs for example are unnecessary and just add to the length of the subtool menu. Using meshInsert to take one eyeball and combine it into the other reducing two subtools into one. This can also be accomplished with the ZBrush plug-in SubtoolMaster. For this to work make sure the two tools have the same number of subdivision levels. This will ensure that both models retail their multiple levels of resolution when combined.

8. Frequent the ZBrushCentral website. The ZBrush user community is one of the most supportive user communities I have encountered. Visit ZBrush Central for updates on new tools, techniques, and plug-ins as well as conversations with other artist seeking critique on their work. If you have a question, posting in the forum will get an answer for you in no time.

9. Use ZMapper to check UVs. ZMapper's morph UV function is a quick and easy way to verify the UV set on a particular ZTool. This can be extremely useful in a production pipeline where you need to verify UV coordinates before proceeding. By simply loading the ZTool into ZMapper and activating morphUV you can check for the correct UV layout as well as visually can for any obvious overlaps or errors in the UV shells.

10. Sketch in ZBrush. Using a ZBrush primitive or a generic mesh, sketch characters often. These don?t have to be show reel pieces just little experiments in using the tools and learning about form. I do at least one sketch a day I never plan on showing publicly. This frees me to make mistakes and just relax. It also helps me learn new things about both using the ZBrush tools as well as sculpting form. Just like you may keep a private sketchbook for ideas and fragments, keeping a ZBrush sketch folder will help you stay active. It can also serve as a great source of inspiration when you want to pick up a rough character and take it to a finish.

11. Use reference. Always have reference handy when working. I personally use photo of real people as well as figurative sculptures when I work. It is hard to go wrong referencing how Michelangelo, Bernini, or Giambologna approached a particular problem in figure sculpture when you work. By referencing the masters you will learn while your work benefits. It is also a good idea to do master copies in your spare time. By trying to copy your reference exactly, you learn an amazing amount about how an artist thought and dealt with specific problems.
