Motion blur shutter speed

[manalokos]

Hello Face,

I've been making some animations around a city with fast camera movements, and noticed that the shutter speed of the motion blur is very very long, longer than the duration of the frames themselves, making everything blurry even with "not that fast" motions.

Will it ever be possible to add the possibility to control shutter speed in motion blur?

Best regards
Filipe

Shutter speed isn´t implemented in Octane, so i can´t add it in the exporter.

Hello,
About motion blur, how does it works ? Is it only for camera move, or does it support object animation motion blur ?
Tank you

Yes I would also like to know

Only camera.
To make an object MB, you need to calculate the difference between 2 frames.
But if Octane is closed, all data is gone and it isn´t possible to calculate something.

This is why the camera MB works, we export the camera position from two frames and Octane can calculate the difference...

Does this mean that the integrated plugins will support full MB?

[face]

Not realy...
For full MB you need two meshes to calculate the difference between each vertex.
Also vertex1 on mesh1 has pos -1,0,0, vertex1 on mesh2 has position 1,1,0. With that you can calculate the distance (2.24) and the direction (0.89, 0.45, 0.0).
This will be needed to calculate the MB...

The Camera has only two positions (camera position and target position), so it isn´t a problem to export it via the command line.

Maybe a post effect?

oh okay so there is no way it was done in octane like the video title suggests
