gaffer - arnold motion blur keys

[Sébastien Desmet]

Hello,

I'm trying to render an animation with motion blur (plane propeller) but I need to have more keys (steps) in my motion blur. How can I do that ?

I don't see the attribute keys in the standardOptions node !

Is this option is somewhere else ?

Thx,

Seb

Thank you Rupert,

Isn't there a global paramater to set the motion blur keys ? are there any reasons why we set that on the object it self ?

Thx,

Hey Seb,

> Isn't there a global paramater to set the motion blur keys ? are there any reasons why we set that on the object it self ?

As it is an Attribute, child locations will inherit their parents value. This means you can set it once at a root location and it will apply to everything below it, unless they have their own values.

Hope that helps,
Tom

Thx Tom for the explanation !

Hello,

I'm back with the motion blur step. I have issue to make the motion blur step work correctly.

here is an image of what I get in arnold maya (right plane) and arnold/gaffer (left plane) with motion blur with the steps set to 10. https://www.dropbox.com/s/elgzmyjjsts611o/motionblurStep.jpg?dl=0

I have enable the motion blur in the standard option and also add a standard attributes with transformation blur enabled and the number of step to 10. On the standard attribute I have connected a path filter with this string "/..."

is there something else to do to make it work ?

Is the abc cache can be the problem ? do we have to cache with substeps ?

Thx,

Seb

I have maybe found the issue. it seems that if we export animation cache in alembic from maya and enable the "fix euler rotations", motion blur is not rendered correctly.

when the option is disabled my propeller motion blur looks correct !
