Blowing Leaves

[RArcher]

Was cleaning up my yard yesterday picking up all the leaves blowing around when I had a thought.  This is what came from that thought.

very painterly!
a fresh and vibrant scene!

[Walli]

very nice colors!

[jbest]

That's awesome colors.

It looks like there was just an earthquake there.

did you think about that - split the trees into a leaf object and a bark object. Then animate the leaf object and render with motion blur. That way only the leafs would be blurred.
Or render out a separate mask for the leaves and then perfprm the postwork blur on leaves only? But that might look strange.

I really love the colours in here. Good idea and execution!

I tried this once ... it was really tough to get the right balance of softened mask for the leaves. Just blurring them would not work. I must be a motion blur.

[RArcher]

Nothing so complicated as that Walli.  Just a very lazy simple setup.  I set a camera keyframe at Frame 1, then moved the camera and set another keyframe at Frame 3, then I rendered Frame 2.  Your way would certainly be more accurate as then the trunks wouldn't be blurred as much as the leaves.

[RArcher]

Just a little further thought on this but I don't think your idea would work right now Walli.  It would seem that only camera movement causes motion blur.  If you just animate the leaves moving they won't blur at all if the camera is static.

This is one of the things I am hoping makes it into the Animation module update as object motion blur is sorely needed.

Correct, there is no object (or other) motion blur, only camera motion blur. To achieve the effect described, you would move the trees with the camera and leave the leaves static.

is object/deformation motion blur something we might see in the future?

I once animated blowing leafs in Xfrog and exported the object sequence to then find out it isn't supported
Rendering a separate mask will likely give weird/ugly results.
