Problem with motion blur

[Kretschi]

Hallo,

I have a moving camera and some geometry moving with the camera (like the view out of a car)
when I turn motion blur on, the object attached to the camera is also blurred...

is it possible to overcome this?


Thanks, Andreas.

You need to add octane object tag and make sure mblur option is enabled.

I tried that. What I need is that the object attached to the camera is not blurred.

Thanks.

It's not strange in LV too. But LV uses caching system for moblur generation and sometimes can display unexpected results when you change somethings. Just play scene and check.

Unfortunately it does not work on my real scene..

I can't get it right..

Perhaps the camera is moving to fast...
Tha camera's animation is baked, but this influence the motion blur.

Here a sample scene where it does not work:


Thanks again.

Why do you select camera motion blur? It disables object motion blur. That's clear that you need to export object's motion matrices to obtain this resuls. Objects are moving too with camera.

@Aoktar - so what is "camera motion blur" used for? Because it's not stated in the manual..
