Activating Motion Blur in Arnold Renderer

In this tutorial, we will guide you on how to activate motion blur inside Arnold Renderer to enhance the realism of your animations. Motion blur adds a dynamic effect to moving objects, simulating the way a camera captures motion in a single frame.

Demonstrating Motion Blur Activation

To begin, ensure you have an object animated within your scene. For example, a sphere moving from left to right. The speed and direction of the animation will influence how the motion blur appears.

  • Set up multiple lights in your scene to illuminate the object effectively.
  • Navigate to the Arnold Renderer tab and locate the Motion Blur settings.
  • Enable the Motion Blur feature to activate it in your render.
  • Perform an interactive render to observe the effect of motion blur on your animated object.

Adjusting Motion Blur Intensity

You can control the intensity of the motion blur by adjusting the shutter angle attribute. This attribute determines how long the motion blur trail will be, mimicking the speed of the moving object.

  • Decreasing the shutter angle will result in a shorter motion blur trail, ideal for fast movements.
  • Increasing the shutter angle will produce a longer motion blur trail, suitable for slower movements.

Applying Motion Blur to Different Elements

In addition to objects, motion blur can also be applied to other elements in your scene, such as textures and materials.

  • By rendering objects with different material properties, like DQS and diffusal, you can observe how motion blur affects each element differently.
  • Import the rendered images and examine how motion blur influences the appearance of textures and materials.

Using Vector Motion Blur

While the traditional motion blur method is effective, consider utilizing vector motion blur for more precise and realistic results. Check out our tutorial on vector motion blur for detailed instructions on implementing this advanced technique.

By following these steps, you can easily incorporate motion blur in your Arnold renders, adding a touch of realism and dynamism to your animations.
