Is the Radial Blur in Fusion Broken?

PostTue Jan 12, 2021 11:09 pm

Hiya,
I'm trying to do a blur that is from the center with Directional Blur. However when I do this I never get the result I expect. I use the DirectionalBlur node.
Radial blur rotates the image
Linear. A straight line as expected.
Centered does not seem to care about Center. It is just a straight blur from an angle. It looks identical to Linear.
Zoom also rotates the image

Or am I doing something wrong? I use Fusion 16.2.4 on Windows 10

Thanks

Set Angle to 0; that's what's creating the twist. You probably want either Radial or Zoom, and just change the Length control. Choose the center point of the blur with the Center widget.

Centered blurs in both directions along the Angle, while linear toward the chosen vector. The Center blur will look identical whether the Length value is positive or negative, but in Linear mode, positive and negative blurs will look different—they smear in opposite directions.

Thanks that did the trick. I have tried over and over but kept getting the swirl!
