Motion Blur Bug: Motion Blur is randomly on when switches are off
In a large animation project, I have all motion blur switches turned off for all individual layers, sub comps, and master switches within them. When ram previewing, it plays just fine, but when I go to render it puts motion blur on random layers, not all. I have triple checked all layers and effects, adjustment layers, there is nothing that has motion blur turned on, built in, or is forcing it. The only way around it has been to turn off motion blur for all layers in the render settings above the output module.
This is in CC 2019, on a Mac Pro, running MacOS High Sierra 10.13.6. Output file is ProRes 422 HQ
Thank you for filing this report.
When exporting via the Render Queue, there is an option in the Render Settings dialog which determines whether or not motion blur will be rendered. By default, the Motion Blur control defaults to On For Checked Layers, which will render motion blur for any layer on which the layer’s motion blur switch is enabled, regardless of the state of the comp’s “master” motion blur switch.
Are you changing this setting in the Render Settings? Does its behavior otherwise align with your experience of which layers do or don’t render motion blur when exported via the Render Queue?
Glad to know that the problem is limited to the single project.
If you'd like us to look at it, post a link to your files here, or if you prefer not to post publicly you can send it to email@example.com. (If you send to that address: A) Do not send .zip files, they will be blocked; renaming to .thisisazipfile is OK. B) Post a comment here when you have sent the email. I need to manually check that inbox.)

Yes I am changing it in the Render Settings. And no, when it is set to "On For Checked Layers", it puts motion blur on random layers, despite there being not a single motion blur switch checked on for any individual layer. It does turn it off when I set it to "Off for all layers", but like I said, none of the switches are on in the first place.
This is only the case in this one project however, and in my others it is working as usual.
Also, what is the point of the Master switch then in the main comp to be rendered? As far as I remember, this used to be the way to turn motion blur on and off. It just makes it more confusing having that control be in the render setting, which makes the master switch purely a preview control.
Thanks for responding.
