Stretch

    STRETCH lengthens or stretches a linked texture. STRETCH deforms in two dimensions.

How Does It Work?

    The Mapping Type parameter sets the direction and origin for the stretch. The mapping types are Planar, Cylindrical, and Spherical. A planar mapping will stretch the texture horizontally from the center or YZ plane. Choosing a cylindrical mapping causes a stretch radially out from the center or Z axis. A spherical mapping will stretch the texture radially out from the center or, in this case, origin. In all three mapping modes, the amount of stretch is 0.0 at the origin, then increases the farther away you get (from the origin).

    Setting the Absolute Flag parameter equalizes the stretch beginning at the origin. If it is not set (no check mark), then the amount of stretch will be nil at the origin and increase continually as the distance from the origin increases.

    The Distortion parameter sets the amount for the distortion as a percent of the maximum. You can link this parameter to a generator to define a distortion profile. The value given to Scale Factor defines the maximum. The direction of the profile changes depending on the mapping type you choose. For Planar mapping, the generator defines the amount of stretch in the vertical direction. For Cylindrical mapping, the generator defines the amount of stretch in a circle, around the origin of the stretch and starting directly to the left of the origin. For Spherical, the generator defines the amount of the distortion from the origin of the stretch outward. When Distortion is not linked, the profile is sinusoidal.

Hints!

    Controling the Distortion parameter with a generator can be tricky and is only useful in a few cases.  The best way to get useful results with STRETCH is to hook the Distortion parameter to a Noise or Natural pattern. This will result in stretching that looks like the noise that's linked to the Distortion parameter.

    In planar mode, with Absolute Flag set, try moving away (translate at least 200 units) from the origin of the stretch. This will move beyond the range where the scaling is affected by the distance from the origin.

Common Parameters

 

 

 

 

Mapping Type

Determines the direction and origin for the stretch.

 

 

 

 

Absolute Flag

When set, normalizes the amount of stretch when far away from the origin.

 

Distortion

This amount is a percent of the maximum (given by Scale Factor).

 

 

Scale Factor

The maximum amount of distortion. Positive means away from the origin and a vlaue of 0.0 means no maximum.
