Motion Blur

Motion Blur

Apply motion blur to objects in a 3D scene.

image

Method #

This node adds motion blur to objects in the scene by interpreting their motion vectors and applying a blur in the direction of motion. This means that effects which does not contain motion vectors will not get blurred, such as alpha blended objects, or changes in topology.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
Blend AmountChanges the opacity of the new effect over the original image.
ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blur ScaleSize of the motion blur applied.
Direction ModeSelect which direction the motion blur is applied.
  • Backwards : Motion blur is generated in the direction of its previous position.
  • Forwards And Backwards : Motion blur is generated in both the direction the object came from and the direction the object is moving in.
Lock Frame RateLock the frame rate of the selected objects.
Locked Frame RateFrame rate to lock the motion blur calculations.
Limit Blur LengthLimit the distance the motion blurs can reach.
Max Blur LengthSet the limit to which the motion blur can be blurred. limit blur length must be enabled.
Line Trace ModeSelect how the motion blurs are calculated.
  • Line (Accurate) : The differences between the two positions are calculated and blurred along.
  • Stepped Samples (Faster) : Multiple substeps are rendered, and layered over each other.
Line Step SizeNumber of substeps for each frame. stepped samples must be enabled.
Apply To Opaque ObjectsToggle whether the effect only applies to opaque objects.
