Selectively Turn Off Motion Blur

[p3taoctane]

I have one object that is moving in my scene.
Its is set to Movable Proxy

The rest are set to scatter. (But there are many of them)

I have turned on internal motion blur and instead of taking 3-4 mins per frame it is like 10-15 mins

I am rendering a 400x200 window at 100 samples...

BUT

The camera is moving in the entire 250 frames.... is it calculating MB for everything in the scene because of the camera move?

If so can I selectively set objects not to motion blur?

Thanks

Did you try Sub-frame motion blur with batch-render ? it may be a quick workaround

[p3taoctane]

I can try that ... but no way to turn off motion blur on a mesh that you know of aye?

[p3taoctane]

Actually I was already on subframe

So no go there.

Thanks for the suggestion though

Peter

Anyone else out there know if you can selectively turn it off on mesh

Hi p3taoctane,

since motion blur is using the whole image and just adds several of them together, its not possible to exclude a single object from that.
In the plugin and in standalone afaik.

Maybe render it on a different layer and composite later?

Cool Kai
Thanks for the response.

Will plan around it.

Colleague suggested Layer ID use. Sounds like a good idea.

Checking real quick... Is it scatter or global that loads the mesh once the first time but not each time.

Thanks

Is it scatter or global that loads the mesh once the first time but not each time.

both,
but Global merge all mesh into one, it add more export time but can speedup the render.

Also, good to know : Global geometry type always use renderLayer ID 1

Thanks mate

I could not find this in the manual... could be there I am sure... but...

To clarify a couple of things....

Octane Geometry type: Movable Proxy
Enables you to scroll the time line and the render view window will update the movable mesh... but motion blur will not show unless you batch render.... Is that last statement correct?

Object Geometry Type: Octane: Constant Topology ...Does this refer to Mesh Deformation or transformations xyz rotat, scale etc as well? (In other words... global and scatter mesh type load once in and animation and of course movable proxy loads each time a new frame is added. If the object moving (MOvable Proxy) but it is not deforming... does Constant topology save rendering time etc? What happens when you select it?

Animation Mode: Full... of course does everything (If motion blur is turned on everything is the scene is analyzed to see if it needs motion blur)
Camera Only ..... only if the camera is moving and everything else is not moving or mesh is not animated and deforming over time (If motion blur is turned on... still every mesh is calculated.)
Movable Proxy...... What is the purpose of this? When it is selected and all the elements in the scene are present...all movable proxies AND Global or Scatter still show in the render. Is it only loading the
Geometry type moveable proxy type each frame and anything else is only loaded the first time??? If so does the NON moving stuff calculate of Motion blur is on?????

Sorry for the length questions but these are related and I am wondering how?

Thanks
