Tri Mesh - No Motion Blur with Next?

[mitchfx]

Running beta 0.16008, Vray Next and Max 2019.  If I render shapes as TriMesh I cannot seem to get any motion blur even on frames where the topology isn't changing.  The topo changes early in the timeline at birth but is constant for 100 frames beyond that, and yet I'm not able to get motion blur to work at all.  Is this a known issue?

That's odd....can you send the scene file to support@tyflow.com? So long as topo isn't changing, moblur should come through.

Tried to repro this on a simple scene....(2019, VRay NEXT 1.2, simple icon flow that stops emitting past frame 100)...moblur after frame 100 in Mesh mode seems to be working fine...if it keeps happening on your end, send the scene
