object motion blur
Hi all,
I have a slot machine animation. The three spinning wheels are strips with a wrap deformer (I liked the way the texture worked better than using a cylinder, that’s why I went with the deformer). They sit behind a plane with openings so we can see the spinning wheels. Here’s the problem. I have object motion blur assigned to each wheel. The frames on the plane are being blurred as well though. These frames do not have omb. Any idea why these are being blurred, and how I can work around this?Mike

Object motion blur AFAIK doesn’t work behind transparent objects (objects with alphas in their materials count to this group as well). Use Scene motion blur instead or do a compositing of the spinning wheels with the mask of the plane in post production.
Kind regards,

Hi Arndt…
The object in front doesn’t have an alpha. it’s a plane and I’ve deleted polys to create the holes. The warped planes are behind it and spinning. on top of the plane is a loft nurb to create a frame. Not sure why the Loft nurb would get blurred…It’s a separate object.

I could be wrong here, but as far as I know nobody in history has ever been able to achieve good results with object motion blur. In other words, I agree with Arndt. You might try Vector Motion blur if you have it. It doesn’t always give great results either, but I’ve been able to get isolated objects like the ones you’ve built to work.
The only virtual guarantee for good motion blur in Cinema is good old scene motion blur. Unfortunately this also guarantees long render times.
