Max exr motion blur setup

3dsMax EXR motion vectors.

The best option is to use the Motion vector G-buffer in 3dsMax.

X : positive is Right – Negative is Left
Y: positive is Down – Negative is Up

In Fusion

3dsMax EXR Motion vector in Fusion


Using the G-buffer fusion in is simple.

In the Loader chose the G-buffer channels for the X and Y velocity.


Then flip the Y channel in the VectorMotionBlur tool to point the vectors in the correct direction.


In Autodeck Composite (toxik)

The Toxik blur tool is actually very cool. The fact that DOF and motion blur are packaged together in one tool is a real advantage over Eyeon Fusion.

This video covers motion vectors in 3dsMax and Autodeck Composite (toxik). But the information can be generically applied. There’s a couple of issues which he fixes in his next video

VideoTip #18 – How to use a Motion Vector pass from MAX’s Scanline renderer!

There’s also a longer in depth look at motion vectors and some fixes if the tools don’t quite behave as they should do.

Dumb 3dsMax Tip of the day … lock the camera

Lock 3dsMax CameraSo I’m in 3dsMax. I’ve painstakingly animated a scene for hours and instinctively middle mouse drag to change view. I’ve now accidentally animated the camera… but I don’t notice until an hour later…. arg

Lock the camera before animating your shot.

Select the camera (and Target). Go to the hierarchy panel > link info > locks , and check all the boxes for movement rotation and scale.

and with a bit of MaxScript…

This will lock the transform of the current object selection:-

setTransformLockFlags selection #all

This will lock the transform of all cameras in the scene:-

setTransformLockFlags cameras #all
