Foam alembic export - no velocities (motion blur)?

[markus_s_cg]

Hi,

I am exporting my foam particles to an alembic file using the 3dsmax 2023 built in alembic exporter (by select the particles in the the scene expolerer and going file export selected).
When I import it as a Vray proxy and render with a vray point shader I don't see any motion blur). What am I missing here?

After you import the files in the V-Ray Proxy, select the Proxy and from the right-click menu go to the V-Ray Properties menu.

Set the Velocity channel to 1 instead of the default one of 0. Then bump up the velocity multiplier for the particles to something like 10.

This way you should be able to render the particles correctly.
