Try adding a bit more light to the scene to see if it helps with the fireflies. I think once you get them under control, it will look a lot better. Can you share the scene?
@grimm, hey,
there is motion blur yes, but it is wrong, eratic, because Octane mix-up particle ID, instead of blurring along the position of the same particle during time, this is blurred between a particle and the position of a different particle.
We have the exact same bug in Maya, and aswell in Max according to Coilbook .
This is very simple to check the problem,
just export to standalone and you will see that the matrix list in the Scatter node is in the reverse order accordingly to how octane use this order to identify each instance.
