Help with blur.....

[Tim Saunders]

What would be the best way to add motion blur to the fan at the top of the image? If the fan weren't behind the wire mesh, I would just do it in ps.

Note, I know there is a way to add motion blur in viz, but being the rookie that I am, I'm not too sure how to apply it.

I am using standard issue viz 2005 with no plug-ins and ps-cs for post render work.

Thanks for any imput you can give me.

G'day,

I don't use viz but in C4D I'd render just the railing to creat an alpha channel onto a PS blured image of the fan.

Cheers

A cheap option......would be to take a flat image of your blades into photoshop before rendering. Create your motion blur then save out your image with an alpha channel for opacity. And then just remove the blades from the fan and map the new image onto a disc where the blades used to be. Its not the best idea, you might have to adjust the image map a bit to make sure it works with the lighting, but it is a quick fix.

wow..tricky.....

 

ok, outta my head solutions:

 

1- forget the fan, just delete it, atleast on this view, with the railing in the way.

 

2- do a more detailed fan, with 4 blades, not 10!.....and render it, the fan doenst have to be on motion, it will look good.

 

3- do what brian suggests

 

I dont think blurring in post production will workr, because its on perspective, but im not PS guru, so i could be wrong.

Yeah, my first thought is to just put in a realistic fan. Just hoping to do something out of my normal style. I have never done something like this and I think it would be fun if I can pull it off. I know it's subtle from this view.

Well, if you animate the fanblades spinning, they'll generate your motion blur. This will work for stills, since the render looks at the position of the fan blade in the frame ahead and behind of the current frame in order to determine the blurred postion. If you set your timeline to 100 frames, and animate the fan spinning 720-1440 degrees after 100 frames, and then render a still from frame 50, it should work just fine. Tune the settings for scanline under the Renderer tab -> Object Motion Blur to get the result your after.
