I'm trying to add some motion blur to a scene. The animation is set up and plays fine, but I can't get the motion blur to work when I render.

I've enabled motion blur in the object properties, and in the Brazil Motion Blur section of the renderer options, (and tried having one off and one on, in case the Brazil renderer overrides the basic MB options) but the image just renders as if it was stationary.

Any ideas?

make sure in object properties you have motion blur enabled (like you said) and set to image

also, you have to use a camera, not just the viewport, that could be your problem

Nope, still not working.

The animation is a simple 10 framed anim, with a keyframe at 0, 5 and 10, with fram 5 at 180 degrees rotation and 10 at 360. (i'm rendering frame 8)

I'm rendering it from camera view.

The object properties and renderer properties look like this:

try setting the properties one to object

i haven't done it in so long i can't remember

I have tried it on Brazil and it blur fine, either image or object blur. There could be one problem if you have a transparent object (glass) in front of your blur object, the blur will not show behind a transparent object. I don't know how to do it in Brazil, you may have to assign a Brazil transparent material to allow it to blur.

I use Mental Ray, and Mental Ray blur everything. behind a glass, also blur show on reflection as well.
