The final stage in adding fur to your models is to render the scene. You can render Fur using the Maya Software renderer or the mental ray for Maya renderer.
Refer to the following table for the differences between rendering Fur in the Maya software renderer and mental ray for Maya. For mental ray specific Fur render settings, see Render Stats and mental ray.
See also see About the mental ray for Maya renderer.
The way that lighting and shading is calculated on Fur is slightly different between the native Maya renderer and mental ray and therefore the resulting renders will differ slightly in this respect; in both cases, an illumination model known as Kajiya/Kay is used, but the intensity at a given point is calculated in Fur's own model for the native renderer, and in mental ray core for the mental ray renderer. This intensity is then used in the Kajiya/Kay illumination model to calculate diffuse/specular components.
