The Render > Environment sub-palette controls environmental reflections.
The Reflect Color, Reflect Texture and Reflect Scene buttons determine how environmental reflections are applied to materials with Environment Reflection attributes. These buttons are only used by the Best Renderer, and are only pressed one at a time.
The Environment Off button disables environmental reflections.
Reflect Color causes a flat color to be reflected in these materials. The color can be chosen using the Environment Color picker, below.
Reflect Texture causes a single texture to be reflected in these materials. The texture can be chosen using the Environment Texture popup, below.
Reflect Scene causes the entire canvas to be reflected as if it were a single reflection map. Because the entire canvas image is used, items may appear to be reflecting themselves.
The Environment Color picker selects the color which is used by the Reflect Color button (above), and is enabled only if that button is pressed. To select a color, you can click once to choose the Main color, or click this picker and drag to any other part of the ZBrush interface.
The Environment Texture popup selects the texture which is used by the Reflect Texture button (above), and is enabled only if that button is pressed.
The Trace Distance slider determines the distance to use when calculating an environment reflection. Larger values can increase rendering time.
The Reflect Repeat Count slider is used by the Reflect Scene button, above, and can have a value from 1 to 5. The Reflect Scene button uses the entire canvas as a reflection map, and this slider determines how many times the reflections are applied before creating the map. When this slider’s value is 1, the canvas is grabbed as is and used as a reflection map. When its value is 2, the canvas is grabbed once, the reflection map is applied, then the canvas is grabbed a second time before creating the map. When its value is 3, the process is repeated a third time, and so on.
Field Of View
The Field of View slider affects the way environment reflections are applied, and can have a value from 0 to 180. Larger values increase the scope of ‘visible’ items in applied reflections, causing more of the scene or chosen texture to be fitted onto the surface of the objects.
