I don't know. I can repro it in Houdini too.

Hi @xsisupport , I believe that usdview cannot edit camera position, so I am guessing that the render camera is switched to a editable perspective camera when the user moves the camera and this editable camera doesn't have the motion blur set. What do you think ?

Can confirm - reproducable in HtoA 6.2.5.2

I tested in HTOA, when editing a scene camera, the motion blur disappear when it shouldn't. This due to the arnold camera being re-created at every camera parameter change plus the shutter parameters not correctly set after the re-creation.
It is fixed by #1855 which should land in the next bug fix release, I double checked in the htoa dev version.

change plus the shutter parameters not correctly set after the re-creation

Would that mean that even with #1855 that if a user were to change the "shutter start" and "shutter end" in Houdini Solaris while the render is in progress that it doesn't update - since that 'set shutter start/end on update' didn't work? Or did it just fail to set it on the new camera since it didn't get any notifications on "Shutter start/end changed" and thus didn't re-apply it.

Anyway, sounds like the camera sync fix might just solve quite a few issues!

Changing the shutter would work now as the camera is not recreated.
