Overview

The VRayHairInfoTex texture allows you to vary different shading properties along hair strands. This texture can be used together with the Hair Material | VRayHairMtl material to control the look of the hair. It can also be used on Hair&Fur, Ornatrix Modifier | VRayOrnatrixMod and Procedural Fur | VRayFur geometry.

Parameters

output – Specifies how the two colors are blended:

Position along strand – Blends between color A and color B based on the position of the shaded point along a hair strand. The color A parameter is used at the root of the strands, and the color B parameter is used at the tip.
Random by strand index – Blends between color A and color B randomly based on the index of each strand. This mode only works for Hair&Fur and VRayOrnatrixMod geometry (but not for VRayFur at the moment).
Hair&Fur color – This mode works only for Hair&Fur geometry; the resulting color is taken from the diffuse color of the Hair&Fur modifier.
Hair&Fur transparency – This mode works only for Hair&Fur geometry; the resulting color is taken from the transparency of the Hair&Fur modifier.

color A – The first color used when output is Position along strand or Random by strand index. This parameter can be mapped in the Maps section below.

color B – The second color used when output is Position along strand or Random by strand index. This parameter can be mapped in the Maps section below.

bias – Can be used to move the middle point between the two colors when output is Position along strand or Random by strand index. This parameter can be mapped in the Maps section below.

seed offset – The random seed when output is Random by strand index.
