Turning on Alpha or Color in such cases eliminates artifacts by additionally blurring the objects. For example, when bright opaque objects pass in front of dark light fog. Sometimes, anti-aliasing performed by the Smooth Value attribute can fail and produce artifacts corresponding to edges in the alpha channel of the unblurred image. The larger the Blur sharpness, the more spread out the blur. If both Motion Blur and Use Shutter Open/Close are enabled, then Maya will open and close the shutter of the camera at the times you specified. If Motion Blur is enabled but Use Shutter Open/Close is disabled, then Maya renders with motion blur and with the shutter opening and closing at their default values, which is.
If both Motion Blur and Use Shutter Open/Close are disabled, then motion blur is not used in the render. This feature is an addition to the motion blur feature.

If a negative shutter duration is set on the renderGlobals node, the software renderer will disregard these values and render as if the Shutter Open / Shutter Close values have never been set. If a user alters the values in the Render Settings window such that the shutter duration is negative, the values will be altered to suit a positive duration. The Use Shutter Open/Close, Shutter Open and Shutter Close attributes can also be set using the renderGlobals node. Default values are -0.5 for Shutter Open and 0.5 for Shutter Close. The default value is 1.Įnable this option to customize the Shutter Open and Shutter Close values. Scales the amount that moving objects are blurred.The valid range is 0 to infinity. The Shutter Angle can be modified in the Special Effects section of the Camera’s Attribute Editor. The length of the frame is determined by: The amount that moving objects are blurred is also based on the Shutter Angle of the camera. For example, if you motion blur by 1 frame, blur is calculated based on the motion of objects from one frame to the next if you motion blur by 4 frames, blur is calculated based on the motion of objects every four frame lengths, during which time much motion is detected, and therefore much blur is applied. The higher the value the more motion blur is applied to objects.
The method Maya uses to motion blur objects.ĢD motion blur is a post-process Maya blurs each object in the image after rendering the entire image based on the object’s motion vector (its speed and direction).ģD motion blur is similar to real-world motion blur, but takes longer to render than 2D motion blur. If it is unchecked, moving objects appear sharp. This means that moving objects appear blurred. If motion blur is checked, the 3D Motion blur type is enabled as well as Blur by frame. Maya calculates the relationship between the Shutter Angle and Motion blur attributes to determine how much blur is applied to an object in scene. You can turn Motion blur on or off for objects in scene. When you render an animation, motion blur gives the effect of movement by blurring objects in your maya scene. Under “Maya Software” tab expand “Motion Blur” section,
To use motion blur in Maya Software engine, Let’s have a look at motion blur techniques in Maya. In 3d animations, moving objects looks much more affective if they have a little motion blur effect on them.
