BUG: First Frame Rendered in Motion Blur Sequence Not Blurred
Last reviewed: April 19, 1996

Article ID: Q149733

The information in this article applies to:


 * Softimage 3D for IRIX, version 3.0

SYMPTOMS
The first frame in a sequence with motion blur rendered using the mental ray renderer is never blurred, no matter where the frame is in the sequence.

RESOLUTION
To work around this bug:

 Render sequences with motion blur with the Softimage 3D renderer. -or- Render the complete sequence with motion blur from the first frame to the last frame in one shot. -or-  If you are rendering pieces of the sequence only, proceed as follows: - Give the rendered images different names, and overlap the images one or two frames so that the blur can kick in. Then rename the resulting frames in order to fit the sequence together. -or- - Render the images in a different location, and overlap the images one or two frames. Then put the frames together once everything has been rendered. 

STATUS
Softimage has confirmed this to be a bug in the Softimage product listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
