maya 8.0 render settings & motion blur

[1armedScissor]

First idea that comes to mind;

Is there animation present in your scene? Either deformation or transformation? If no animation is present (either on your assets or your cameras) then there will not be any motion vectors present to calcluate the motion blur.

[Luisk]

yes, theres animation...theres a character moving and throwing a prop he's holding..

thanks,

Copy and paste this into your script editor and press enter. Render again. Does this help?

global proc oogaBooga()
{
setAttr miDefaultOptions.motionBlur 2;
setAttr "miDefaultOptions.motionBlurBy" 1;
setAttr "miDefaultOptions.shutter" 1;
setAttr "miDefaultOptions.shutterDelay" 0;
setAttr "miDefaultOptions.timeContrastR" 0.2;
setAttr "miDefaultOptions.timeContrastG" 0.2;
setAttr "miDefaultOptions.timeContrastB" 0.2;
setAttr "miDefaultOptions.timeContrastA" 0.2;
setAttr "miDefaultOptions.motionSteps" 1;
setAttr "mentalrayGlobals.previewMotionBlur" 1;
}
oogaBooga;

hey ooga booga...no it still renders without blur....is that the same preset as setting the quality to ProductionMotionblur?

thanks for the help!

No worries mate. It's my pleasure.

It's the same with one exception, the "previewMotionBlur" attr. Is it possible for you to post your scene? what version of maya are you using? if you start a brand new scene, make a polySphere, animate it, set your renderer to mentalray & use productionMotion blur & render it do you get motion blur?

[Luisk]

fixed it!...I did what u said and then compared the settings, my scene with the polysphere scene..I had 2 options checked so it wasn't working...
thanks thank you so much!
I had another question..the prop blurs when it moves but the arms of the character don't..why is this?

[1armedScissor]

What were the settings you didn't have set correctly? Is it that your characters arms don't have motion blur at all? or is it just perhaps not as much as the prop? Is the prop moving faster in relation to the arms?

[Luisk]

custom motion offset was checked and the preview motion blur was unchecked even when I used your script....
the prop is in the character's hand and it blurs but the hand doesn't...the prop is a black phong material and the character is a red lambert material.

can you post the scene file? or replicate the problem in one that you can post?

cheers
