The Redshift for Houdini plugin can render as Redshift hair the Houdini curve primitives and the Houdini Fur objects. The RS hair is rendered with motion blur if the hair object has the velocity parameter enabled. The plugin also extracts automatically the UV map at strand level if available, that can be used with the texture sampler node to shader the hair.
To render the Houdini fur in Redshift, follow the next steps:
- Select your object and create the Houdini Fur using the Add Fur button on the Fur shelf. This will create the fur node.
- In the Basic tab set the Type to “NURBS” and set a material SHOP for the hair.
- In the Render tab, set the Render Style to “Direct”
Houdini 16 hair system
The plugin can render the fur information computed by the new Houdini 16 hair system. In Mantra, the new hair system works as a procedural object, expanding the fur information at render time. Redshift can render the fur curves extracting the geometry from the hair generator SOP nodes.
To render the Houdini 16 fur, the hair generator node must be configured to "Use SOP Geometry". This means that Redshift is going to render the SOP data that is computed for the viewports as real Houdini curves or polygons primitives. Due to this workflow, some display optimizations like the “Limit to Bounding Box” option can’t be used while working with Redshift. Of course, if you want to hide the computed fur in the viewports, you can edit the hair generator node SOPs and set the display flag to a null or other kind of lightweight SOP.
