motion blur question

For the first time I´m in need of Octanes 2.0 (2.05a) motion blur feature.
In my scene there is a train driving through a city. The camera is linked to the train, so it has the same speed as the train. The camera is moving only very slowly along the train to highlight some technical points of interest.
I just want to have camera motion blur active to blur the city in the background and the objects near the railway in front of
the train. But octane always blurs the whole render. It treats the train the same as the background, although the camera
is moving with the train.
I have disabled the train from motion blur in 3dsmax object properties and the vertex- and object-motion blur option in octane
object properties. The motion blur is only activated in the Render settings.
What am I doing wrong?

I made a small test szene with an animated and a static camera.
There is one box static and one box moving.
The camera motion blur works fine on both boxes. The object motion blur of the animated box works
fine from the static camera and is also added to the camera motion blur when viewed from the
animated camera.
But when I take a box, put it right in front of the animted camera and link it to it, the box is always blurred. It looks a little different from a standard and an octane camera, but is always effected by
the motion blur. Is this a bug?
It has nothing to do with FOV, I deactived that.

Can you post the test scene?

You should switch on train motion blur. Set movable proxy and object motion blur option for every train objects.

That did the trick, thanks!
I thought I had to disable motion blur settings for object not to be blurred
Does the motion blur settings in the standard 3dsmax object properties still have any effect?
Is this controlled with the "use object render settings" option under Kernel/Render settings??
Or can i ignore this completely and adjust everything with the octane object properties?

If you disable motion blur object, it will act like a static object (no motion relatively ground, but moving relatively camera in opposit direction) and camera motion blur will blur it as all static background objects.
You have to tell that this object is moving with camera (no motion relatively camera)
At the moment octane uses next standard object properties:
Visibility
Renderable
Visible to Camera
Cast Shadows
All other standard settings are ignored.

Thank you.
That made it clear
