Motion Blur missing in some frames

Hi Paul

I have a problem with camera motion blur.

I have scene with replicators and a terrain with displacement map. Camera motion is fast.

Some of the frames have no motion blur. Looks like its random frames. Is this a bug or is there a work around?

Using Modo 14.1v1 and octane 2020.1 (8010000). And I am rendering inside of Modo and not in Octane Standalone.

Thanks

Hi

I am not aware of an issues that would cause this. Which version of the plugin are you using please? Do you have a sample scene which exhibits this issue that you can send me?

Hi Paul

sorry for the long delay. Just in the midst of projects.

I have attached 2 Modo scenes.

Modo 14.1v1 using Modo plugin Enterpise 2020.1.4.162

MotionBlur_Replicators ( a plane emitting particles and the Replicator is replicating the teapot on the plane)
MotionBlur_NoReplicators ( in this scene the Replicator teapots are "frozen" ...now the scene is not using Replicators)

In both cases the Camera is animated and Camera motionblur is on.

When I render the scenes some of the frames don't have motionblur.

First I thought it might be Replicator problems but the missing motionblur also happens in the scene that is not using Replicators.

I have attached both scenes

I have referred this issue to OTOY. I will let you know once I get a solution.

Thanks

Hi Paul

I have downloaded 2020.1.5.163

Tested with the scene I provided you. It works. All frames have motion blur.

I will do more tests with other scenes and report back if I run in to any issues.

Thanks for the quick fix.
