Blender/Octane Motion Blur not working

[Dhenzel]

Hey everyone -

I'm trying to render out something in Blender/Octane (( 020.1.4_21.13 )) with motion blur, and it doesn't seem to be working even with all of these boxes ticked;

• Motion Blur checked in Rendering Settings
  Motion Blur checked in Camera
  Motion Blur checked in the objects I want motion blurred.

Noting as well the objects I want blurred are a Collada/.dae file imported from Mixamo + a garment rendered as an Alembic OGAWA from Marvelous Designer
Camera is stationary, doesn't need to be blurred.

This doesn't seem to be a problem with a simple cube animation though, the motion blur works fine there.

I was suggested that the Alembic file is just frame by frame mesh data, so there's no data inbetween/interpolation to show movement - no idea if there's a way to get an alembic file to have this data?

The armature from mixamo shouldn't have this problem though, right?
Though, it doesn't seem like there is any position changes in the armature or mesh thats Blender is reading.

Been struggling for a bit & would appreciate any help with this.

Thanks

Update:

Found that the main problem was my textures had displacement maps - Octane doesn't seem to render motion blur with those.

Is there a work around that?

Hi,
probably you are using a Texture Displacement node, that does not support motion blur.
You need a Vertex displacement node to have correct motion blur on the object.

Ahh, thank you for this
