View Full Version : Rotation Blur
LT Fox Fire 08-17-2003, 06:39 PM How can you get a rotating disk or blade to appear like a blended blur and not as an object clearly seen, spinning fast?

Have you tried using Motion Blur? I've got AM2000 8.5L, and in the Render Panel there's a tab for Final Options 2. Check on Motion Blur, and you can set the Shutter from 90-360 degrees.
You'll probably have to experiment with the settings while finding the rotational speed that gives the best effect for your model.

try AM 10.5. it has a multy pass renderer wich sould do a good job combined with motion blur. but to be honest i still use 10.0 and i didn't try it yet. maybe it takes a while to render enough passes to achive a good look.

I'd most likely fake it with an alpha map (or two for animation) for transperency and procedural texture or something. I mean if it's for something like a propeller.
If it was animated, using a sequence of decals might work really well, this way you can control how it appears more precisely than with AM's rather half-baked standard motion blur. While I've heard good things about the multi-pass version, the one in the basic package is finicky to get to look good.
Like rapidly flapping insect wings, I'd just model them as a volume and texture them appropriately and they'd appear to a blurry motion, but in reality are jsut partially trtansperent volumes where the wing passes through. Then I'd have stationary wing model for slow wing movements.

Since I have AM 9.5 I'll try the motion Blur option. I knew I saw that somewhere but I just had to be reminded and to be honest, I was not sure what it did. I'll post a finished .mov file when I get the blur into the animation. Thanks for all your help guys.
