Render scenes with hair
 
 
 

Hair using Paint Effects can be rendered directly using the Maya Software renderer. If you convert the Paint Effects to polygons, then you can render Hair in the mental ray and Maya Hardware renderers. (See Convert Paint Effects to polygons in Paint Effects.) Alternatively you can output just curves to another renderer, such as RenderMan.

TipYou can render more hairs cheaply using Paint Effects Multi Streaks. These attributes are in the Multi Streaks section of the hairSystemShape.

You can render either a single frame, or render an animation by performing a batch render. For information, see the following:

To render a single frame with hair

  1. Before rendering be sure to display the hair system’s Current Position ( Hair > Display > Current Position) and go to the frame you want to render.
  2. Click the Render Settings button in the Status Line and do the following:
    • Select a renderer from the Render Using drop-down list.
    • If you’re rendering Paint Effects using the Maya Software renderer, then turn on the Oversample and Oversample post filter options in the Paint Effects Rendering Options section in the Maya Software tab. This makes the hair even more realistic looking.
    • If you’re rendering using mental ray, see Render Settings: mental ray tabs for information about the options in the mental ray tab. You can use the Production: Rapid Hair Quality Preset when rendering hair in mental ray (Render Settings window, Quality tab). Alternatively, you can use the Production: Fine Trace Quality Preset as a starting point if you want to trace fur or hair in reflections.
  3. Click the Render button in the Status Line. This renders the current frame in the Render View window.

To render an animation with hair

  1. Before rendering be sure to display the hair system’s Current Position ( Hair > Display > Current Position).
  2. Click the Render Settings button in the Status Line. The Render Settings window appears.
  3. Select a renderer from the Render Using drop-down list.
  4. In the Common tab, do the following:
    • In the File Name Prefix field, type the prefix you want to use for the rendered images.
    • In the Frame/Animation Ext field, select name.ext.#.
    • In the Start Frame and End Frame fields, type the first and last frames in the sequence you want to render.
    • Optionally, go to the renderer-specific tab and turn on Motion Blur in the Motion Blur section.
      NoteThe animation will take longer to render with Motion Blur turned on.

      Motion blurred scenes would benefit from scene caching to prevent simulation problems during frame sampling. See Use hair caches.

    • If you’re rendering Paint Effects using the Maya Software renderer, then turn on the Oversample and Oversample post filter options in the Paint Effects Rendering Options section in the Maya Software tab. This makes the hair even more realistic looking.
    • If you’re rendering using mental ray, see Render Settings: mental ray tabs for information about the options in the mental ray tab. You can use the Production: Rapid Hair Quality Preset when rendering hair in mental ray (Render Settings window, Quality tab). Alternatively, you can use the Production: Fine Trace Quality Preset as a starting point if you want to trace fur or hair in reflections.
  5. Do one of the following:

    To view your rendered animation, launch Fcheck and then open the rendered.iff file. For more information on viewing the animation, see the Rendering guide.

Rendering using distributed render

If you are performing a distributed render, or if you are splitting up the render for any reason, you should create a hair cache. Creating a hair cache lets you do distributed rendering and have the simulation match exactly.

For details, see Use hair caches.
