Render Modes
From ZBrush Info
ZBrush provides several render modes for flexible working.
Controls
Preview: The default renderer, used when composing a scene or sculpting. It will show most properties of the scene including Preview Shadows but excluding Light palette shadows, complex fog, light colors, depth cue and some material and other effects. It does show transparency, but the Best renderer is significantly better in most situations.
Best: Used for the final render, the Best Renderer uses the best (and slowest) methods to produce the highest quality image. Shadows must be rendered using this renderer.
If you try to work in the Best Renderer mode, ZBrush will automatically switch to the Preview Renderer. There's one exception to this; if you have a floating object in the scene, you can make changes to its material properties and the Best Renderer will re-render only the object and its bounding box.
Fast: The fast renderer does not render materials, only basic shading. This makes it ideal for modeling, since it is very fast and shows surface details due to geometry, not materials.
Flat: Allows you to see the scene with no shading, just basic color. This can be useful for checking texture maps.
Cursor: When you drag the Cursor button to the canvas, a sample area centered around the mouse release position is rendered using the Best Renderer. To re-render the same location after making changes, press Ctrl-R.
Render: Causes ZBrush to render the entire document with the current settings.
