motion blur if cam and object is moving?

[sascharossier]

Hej Folks
Ive got the following shot:
https://dl.dropboxusercontent.com/u/171 ... INAL_1.mp4

(Elevator-Like vehicle hovering downwards ... camera and object are moving independently of eachother)

in render settings i got motion blur switched on
duration 0.5 (that should equal a 180 degree shutter)
on every object i got motion blur activated, vertex motion blur activated, movable proxy on
(actally i tried any combination of activated settings in object settings, even the object settings
in the octane-camera ...

I do get motion blur ... its clearly visible ... but it doesn`t seem right ... cause
it still flickers around some edges ...

can somebody help me out with this? I seem to do something wrong here
Thanx in advance

and ...yeah, let me say this ... even with all the bugs and problems ... octane is easy the most
awesome renderer i ever used Arnold might be better, Vray might be better, Renderman might be better ...
but nothing is as lightning fast as octane ... Thanx a lot, guys!

You should set motion blur duration to 1.0. It means 1 frame duration. In this case the motion will be smooth.

Thanx 4 ya Quick help karba. Its still flickering a Bit, but Its much better than before... So does that mean, that a 1 frame motion blur equals a 180 degree shutter angle?

I have no idea what 180 degree shutter angle is.
1 frame means duration of frame. If you set 30 frames per second, so frame duration is 1/30 of sec or 0.03333 of sec.

My first Post. Yay.
@Karba Some people like to setup their motionblur the old way. This explains it pretty good:
On 24 fps

180° = 1/48 frame duration, 360° = 1/24 frame duration
