Hello

I am trying to render out a shot of an object with motion blur. It looks absolutely fine in the Live Viewer, but when I render it out in the Picture Viewer, it looks terrible.
I've read in another thread that "the liveviewer isn't meant to preview motion blur". This is of course a big flaw in how the C4D plugin works, given how important motion blur can be in a final image, but I could maybe understand that it needs to be that way for things to work smoothly under the hood.

But what I don't understand is why my motion blur would actually look worse in the Picture Viewer than in the Live Viewer? I don't know what I'm supposed to do to efficiently and comfortably work on my image. Could someone share a tip or a workflow on how to efficiently lookdev motion blur, in Octane?

- Here is what it looks like in the Picture Viewer (disregard the color mismatch, just ACES not showing up properly in the picture viewer) : https://i.imgur.com/JGbDdcG.png

- I am running Octane version 2023.1.2-R6, with Cinema4D 2024.1.0

- The object itself is some geometry inside of an XRef object, that is itself nested under a moving alembic : https://i.imgur.com/UkW2yrj.png

- Time Sampling Per Frames is set at 32

Thank you,

I don't mean to sound patronizing, since I do this to myself all the time: Have you checked to make sure that your C4D render settings have Octane designated as your renderer instead of the default Standard renderer?

Hi,
I suspect that the issue is in the hierarchy, what happens if you freeze the Xref object, and use the real object instead?

Please also try to move the Octane Object tag to A_3 parent.

ciao,

What are the motion blur settings on your octane camera tag? I've had similar problems in the past when trying to push motion blur beyond 1 frame's worth of time. eg if you have a 30fps video, you shouldnt make the motion blue length any longer than 0.0333 seconds or the blur will be longer than the frame time.
