Here is a link to a test video clip I rendered
1.45 meg quicktime

I used a Maya blinn material along with the mental ray mib_amb_occ texture which I plugged into the color and ambient channels of the blinn.

Here are the amb_occ setting I used:
64 samples
spread: .8
Max dist: 30
reflective: on
Mode: 0
Falloff: 1

I rendered using mental ray production settings. There are no lights in the scene. I set the max dist to 30 because I didn't want the floor to create too much occlusion on the underside of the model. At 0 the underside of the model was too dark. I set the reflection to ON because it gave a more interesting look.

As you can see in the video, the camera is doing a simple turntable loop around the model. The occlusion texture is working well except that it is strobing. I don't know why it is strobing. I want to use occlusion passed for compositing but it won't work with the present results I'm getting.

Any ideas on how I can eliminate the strobing?
