Motion Blur in Nested Comp Problem

[Walter Soyka]

[Barry Goch] “Every time I render out the piece, there is no motion blur on the elements that should have it. I’ve checked to see that motion blur is turned on everywhere it is supposed to be, but I don’t know what I’m missing.”

Do you see motion blur when you preview, but not when you render? If so, you should double-check your Render Settings in the Render Queue to make sure that Motion Blur is not turned off there.

If not, then you probably still have moblur turned off somewhere; it must be on for the layers you want to blur, and it must be turned on at the top of each of the pre-comps’ timelines.

I figured out what was wrong. I turned on the Open GL rendering and it turn off the motion blur. Go figure.

OpenGL does seem to cause many problems, and disabling it is usually one of the first troubleshooting steps to try.

Check out Todd Kopriva’s recent post on this for more: basically, you can leave it on for interactions, but you should disable it for preview and render.
