Because a soft body includes a particle object, special circumstances arise when you render the soft bodies with motion blur. See the Rendering guide for more information on rendering.

To render soft bodies with motion blur

1. In the Attribute Editor for the soft body geometry, turn on Motion Blur in the Render Stats.
2. In the Render Settings window turn on Motion Blur.
3. Do one of the following:
   • Set the Blur by Frame in the Render Settings window to 1.
   • Select Solvers > Create Particle Disk Cache to create a particle disk cache before rendering (see Particle disk caching).
