This page provides information on the Hair Properties in V-Ray for Houdini.
The Hair Properties can be used to fine-tune the rendering of hair with V-Ray. They allow you to control the hair shader and the hair tessellation during render times.
To add the Hair Properties, select the Geometry node and click the Hair Properties button residing in the V-Ray shelf, or use the V-Ray menu in the top menu bar. This creates a spare parameters folder under a V-Ray tab on the Geometry node.
When rendering a heavy hair/fur setup, you may benefit from reduced RAM consumption when the 'Render as Smooth Curves' option is enabled. This will instruct V-Ray to perform an optimization step prior to rendering the groom. The optimization step will remove redundant vertices and keep only as many points as are needed to preserve the shape, similar to the way Houdini's Resample SOP can be used to optimize point count for polygon lines. |
For more information on the hair properties under V-Ray Object Properties SOP, see the V-Ray Object Properties SOP page.
