Volumetrics Options
Note
The options on the Volumetric - Basic and Volumetric - Adv tabs are only available when the Render Selection pop-up menu is set to
Volumetrics Only.
The Volumetrics options are used when the HyperVoxels object is used for gas- or cloud-type effects. Use the Color, Luminosity,
Opacity and Density options on the Volumetrics - Basic tab to change those parameters for the volumetric object.
The Fractal Noise pop-up menu lets you select the type of pattern. fBm applies a turbulence pattern, while Puffy provides areas of
less-dense "puffs". The Fractal option yields sharper-edged patterns. Use the Fur option for hair. It is like static Billowing (See
discussion on Advance Volumetric Parameters). The pattern may have a Local or World reference. It may also be parented to an
object using the Parent pop-up menu.
The Frequencies, Scale, Amplitude, Filter, Gain, and Bias options work the same as previously described for the HyperTexture
Options tab. The small preview window has some other options, however. By default it shows a small preview of the pattern.

ATTERN REVIEW
Clicking the preview will cycle you through different options:
• Cross-section image of the pattern (default)*
• Cross-section graph of the pattern
• Thumbnail example of the pattern*
*If you hold the C
image will be displayed.

UTOMATIC REQUENCIES
For volumetric textures, setting Frequencies to a value of 0 activates a special automatic frequency mode. This dynamically calculates
the amount of frequencies depending on distance from viewer, resolution, etc. Essentially, an automatic detail refinement process is
performed.
Hint
Setting Frequencies to 0 is usually the optimum setting and is highly recommended in most cases.
