Hi coilbook,
Sorry for the delay.. I will investigate soon.
Could you post a sample scene ?
Thanks

Hi,

Here is the scene. By the way, are you, guys, working on procedural clouds for octane or planning too? Vray has it and Corona 9 will have it too soon. Thanks

Hi coilbook,

Thank you for the sample scene!

It works, but we can't use 'Vertex motion blur' that would need to have a mesh with constant number of vertex and polygons.
Instead, we can use the vertex velocity, that is created by tyFlow, and available as a map channel of the object.

I found that map ID 20 was used (not sure where is it set in tyFlow UI ..), using the Map Channel Info tool ..

So, in Octane Object properties, disable Vertex motion blur and set 'Velocity channel ID' to 20

And use Render settings / Support / 'Generic Velocity Scale' to adjust the velocity . values around 1.0 seems fine for this scene.
You can also adjust the camera motion blur duration / shutter time as usual.

I disabled 'Subframe moblur' / 'Only at render time' in tyFlow, but it doesn't seems to matter...
Here is the updated scene: For the procedural clouds, I'm not sure .. I guess some Vectron object could do it, but someone has to write the osl code .. maybe you could post a request in the Stand Alone forums..

Thanks

Hi, What about phoenix liquid. Same problem. I used to use vertex mb and now it doesn't work. My newest post viewtopic.php?f=81&t=81080

Thanks
