View Full Version : MAYA Motion BLur : 3D vs 2D
11-10-2003, 04:31 PM
I need help and suggestions to manage Motion Blur in animation scenes.
Is there anyone that knows Maya Motion Blur behaviour ?

generally what I do is use 2D, unless it looks bad, then use 3d.

Maya's motion blur is a rather strange thing at times. It can produce good results, and it can also produce some rather strange rendering errors.
2D motion blur is a post-process that occurs after the main render. It doesn't calculate the movement of objects in the scene, but rather the movement of color in the 2d render space (I believe this is correct, but could be wrong...)
3D motion blur actually calculates the movement of objects in 3d space. The motion blur might look pixelated, you may have to adjust the settings for good results.
I generally use 2d blur on most of my personal stuff. However, the benefit of 3d blur is that you get rotational blur, which you won't with 2d blur. Or at least, it won't look as good with 2d blur.
For an ice skater spinning at full speed, I'd use 3d blur, mainly to get the rotation blur correct. For a spaceship racing across the screen, 2d should work fine.

YEs....I've done some tests....I've noticed few result differences, but big rendering time differences!! :)
so ...at the moment, I choose 2d Mblur.
Thank you for your suggestions...very useful
