The Direction, Length, Thickness and Gravity parameters in this rollout add variation to their corresponding parameters from the Parameters rollout. Values range from 0.0 (no variation) to 1.0. See the Variance examples below for more information.

Bend Direction Map – Specifies a bend direction of the fur strands. This is the direction the fur strands are curved to (the amount of curvature is also controlled by the Bend parameter). The red component of the texture is offset along the the U texture direction, the green component is the offset along the V texture direction, and the blue component is the offset along the surface normal.

Initial Direction Map – Specifies the initial direction of the fur strands. The red component is offset along the U texture direction, the green component is the offset along the V texture direction, and the blue component is the offset along the surface normal.

Variance Direction

Variance Length

Curl – When enabled, adds curls to the fur.

Curl Radius – Specifies the radius of an individual curl. See the Curl Radius example below for more information.

Curl Radius Variation – Allows you to add variation to the curl radius of the fur strands.   See the Curl Radius Variation example below for more information.

Number of curls – – Specifies the number of curls on a strand. See the Number of Curls example below for more information.

Curl Map – This Map – This map is a multiplier for the strand strand Curl. Black portions of the map correspond to no curl, and white represents the set curl, as specified by the Distribution parameters.

Level of detail – When enabled, V-Ray will generate less fur geometry for parts of the project that are far away from the camera. This is done by decreasing the density of the fur strands and increasing their thickness. The level of detail function helps for two things. One, it conserves memory by decreasing the detail where it is too far to be visible, and two, it helps to reduce animation flickering of very fine fur strands when they are far from the camera.

Start distance – Specifies the distance from the camera at which V-Ray will start implementing the Level of detail adjustment. Up to this distance the fur will be generated as specified by the user. After that V-Ray will decrease the density and increase the thickness of the strand by a factor of two for every n units every n units of space specified by the Rate parameter. See the Start distance example for more.

Rate – The rate at which the Level of detail adjustment is applied. Starting from the distance specified in the Start distance parameter, V-Ray decreases the density and increases the thickness of the strands by a factor of two for every n units of space specified by the Rate parameter. See the Rate example for more.
