I have some Text items set up in 3D space, they are 3D unrolled Comps because they're multilayered and won't display properly if they're 3D planes.
I want to move the camera between them, which it does by following a point that moves to each item in turn. I want to apply motion blur, but nothing is apparently moving -just the camera - so that doesn't work (Why can't it work out that's the same thing?).
Then I thought: Grade Layer and the Motion Blur Effect.
Result: Weird splodge artifacts streaming off the edge of straight lines and other messiness.
I do not want to have to move all the objects around and keep the camera still, because that would be more complicated and less versatile, so is there another method?
Edit: Forgot there are other settings in the Motion Blur Effect, so changed from Comp Settings to Custom and messed about a bit.
That improved things...until I rendered the output when it did this for a single frame.
Kinda Sore thumb.
