Focal Length change & Motion Blur

[twistedpoly]

Hi everyone,

i just ran into something that seems like a limitation with Motion Blur, so just checking if this is correct or there is any kind of workaround.

Motion blur doesn't seem to pick up Focal length change on Camera, so for instance when Zooming in or out, there is no motion blur at all.
Is that something that is a known limitation and does anyone know a good workaround? I did try camera morphing between cameras with different focal lengths but the problem is still there.

Cheers,
Nejc

Hi,
if your are referring to the Camera MB, a position transformation is needed.
here is a test by adding a bit of movement to the camera to introduce the MB:

thanks beppe, but what I was talking about was strictly motion blur that comes from changing focal length / zooming. So movement of camera doesn't have anything to do with this. So imagine having a still cam that quickly zooms in or out of something

I just found this thread which proves this is not implemented yet - viewtopic.php?f=30&t=46615

thanks!
