OTOY's plans for motion blur in liquids

[coilbook]

how were they able to have iray have mb with liquids

Thanks[/quote]

I don't know it but most likely by a special function which gives velocity vectors. Because you can't follow a vertex on next frame. ID will change. Only way to do by a speed/velocity vector. Currently we have support in Octane for motion blur by speed vector. But we need to have a functionality to read this data. I don't know it on max but it's very problematic in C4D's sdk that's very limited and unproper for octane plugin's workflow.[/quote]

I see Thank you
Hopefully after Octane 3 is out you guys will be able to find solution for mb in liquids, gases etc. Especially big companies will be demanding mb for their animations if they use OCtane

Does this mean that also motion blur for volumetrics like smoke won't be supported in V3? From what I've seen of V3's features for animated volumetrics you have to load a different VDB mesh for every single frame, I would imagine this would cause a similar problem.

Volumetric motion blur will be supported in later versions of Octane 3, possibly 3.x in case of unforeseen circumstances. CFD sims typically export a velocity grid within the same VDB, effectively giving each voxel a velocity which we would sample sub-frame.

These are great answers, thank you guys!

in octane proxy enable support alembic file format? and problem will be solved.
