VRayHairFarmMod Overview

The VRayHairFarmMod modifier can be used to render hair strands produced by the Hair Farm plugin by CyberRadiance. This allows the hair to blend seamlessly into the V-Ray rendering pipeline and to properly interact with features like 3D motion blur, V-Ray lights, global illumination, etc.

Please note that VRayHairFarmMod requires Hair Farm 2.0 and later.

When using VRayHairFarmMod modifier on a Hair Farm object, you will have to disable native Hair Farm rendering by turning off the Use Hair Farm Renderer option in the Hair Display modifier. Otherwise, the hair will be rendered by both V-Ray and Hair Farm.

You can use any V-Ray materials on a hair object with the VRayHairFarmMod modifier, including VRayHairMtl and VRayHairInfoTex.

Parameters

generate w coord - when enabled, V-Ray will generate a W mapping coordinate that represents the position of the shaded point along the hair strands. Otherwise, the W coordinate is taken from the Hair Farm modifiers.

Notes

• The generated strands are dynamic geometry; as such, they respect the Dynamic memory limit setting in the V-Ray raycaster section. If you have lots of hair strands, it is recommended to increase this value.
