I'm trying to export a Motion Vector pass in Octane 3 for C4D.

I enabled the motion blur on the camera tag and have enabled the motion vector pass in Octane render settings - but just getting a black screen for my motion pass.

Is there an issue with export motion vectors in V3.03?

There is no bug. But first try with latest builds first. And send a scene to let me help and explain. You may need to do a proper setup in passes.

Hi Akotar, thanks for the quick reply.

I've just installed the latest build of Octane for C4D and still getting a black frame for my Motion vector pass.
I've attached screen grabs of my settings - both Render and Camera tag - have I missed something?

Regards

Can you test your motinblur with disabling passes? Can you see any mblur on objects?

When I disable the motion vector pass I get motion blur in my image and in the Live viewer. It's just when I enable the individual pass that it doesn't seem to render any of the motion vector pass - just a black screen.

Do those settings look normal? Should I be bumping up my shutter?

Here's some grabs: (can't post stills of my project) but here's me just testing it on a basic scene.

With motion blur just on camera tag: When I enable passes I just get a black screen in my multi-pass:

Object has motion or it comes from camera movement? Do you have object tag on object?

The camera is static and the motion is coming from the moving object...
Settings are set to 'Full motion blur'.

Yeh it has an object tag on it. Do I need to enable motion blur in there somewhere?

This is a working sample.
Created a new scene. Added some motion and object tag to objects.
Enabled motion blur in camera.
Activated motion_vector pass.
That's all.

Can you post your test scene?
