Anyone got any tips for getting motion blur with Octane and X-Particles to work?

I've got a scene with a fluid coming out of a pipe and I can't seem to get motion blur to work (only tried Live Viewer window so far).

My X-Particles setup is an emitter, and a skinner and a gravity modifier. (It looks like a thick, gloopy liquid, like unrefined oil).

I've cached the particle system and added Octane object tags to almost everything in scene (progressively, trial and error) and I definitely have the motion blur setup right in my Octane camera.

I've also Googled this and read quite a few forum threads but can't find anything which addresses the problem.

Any ideas?

Cheers.

You have to select "transform/vertex" mode for deformed objects and these have to be having constant vertex amounts. Skinner objects propably will not provide a constant vertex counts.

Thanks for the prompt response aoktar.

I tried doing what you suggested and it still doesn't work.

Presume it's a vertex problem as you suggest.

I guess I need to research X-Particles more and find a way of simulating fluids that will create constant vertex amounts, if that's possible.

Cheers.

Propably yes! Another new option is vertex speed option. it will require x,y,z components via vertexmap tags.
See this post for setup. It's a similar question.

I've tried adding a vertex map tag to the skinner object but it won't work, I think because it's not baked geometry?

Anyone know how to do this with X-Particles?

Cheers.

You'll see that these tags are produced by realflow plugin's itself. You have to find a way to link/transfer correct speed values to these tags. It may not be supported as being in RF plugin.

Ah, thanks.

If I could bake the skinner animation mesh into C4D somehow would that work with Octane motion blur?

I think no! Maybe export/import as alembic works, but not sure. Because correct values in these tags are critical requirement.

This plugin looks like it will do something similar with the X-Particles skinner mesh that Real Flow does with its meshes, I think.

This would presumably turn the skinner mesh animation into something with keyframes that Octane would recognise for motion blur?
