Can’t get Camera Motion Blur to work

Octane Blender 2020.1.5_21.15

If I export ORBX and bring into Stand Alone it works fine.

Is there another setting in Octane Blender maybe I’m forgetting?

No blur occurs in the Octane Blender file. But if I export as ORBX and render in Stand Alone the camera blur works fine there.

Motion Blur can only be seen in the final render, not in the preview.

Yes I know. No camera motion blur is occurring in the final renders - I rendered a few frames forward and back to check.

I added the motion blur in After Effects but would like to know why it is not working in Octane Blender (works fine in Stand Alone).

There has been issues with motion blur in the past. I tried to get it to work, but was unsuccessful. Here is a short 20 frame animation that moves the camera, but no blur. I tried several different settings, render still frame and animation, but none of them worked. This is using the latest version of the plugin.

Do you have the motion vector pass turned on? That automatically disables motion blur in the beauty pass. It should do so in standalone as well, but throwing it out there just in case.

Thanks joenyc,

I double checked, but no, I didn't have that pass turned on. I did have the denoiser turned on (it's not working either) and after turning it off, no motion blur.

Ok, I think I got it figured out. You need to enable motion blur for each object in the object properties. Here is my new scene with working motion blur.

Grimm, you're the best! That's the secret. Camera Motion blur now works on my scene.

If you don't have animated objects in your scene but the camera only, you just need to activate MB on one of those to be able to use the Camera MB.
