Motion blur on changing topology alembic issue

[dgani]

I'm enabling motion blur in my scene which has an animated alembic, and the animated alembic shows up just frozen on the last frame of animation. I ran a few tests and found that generating a motion vector pass causes this issue. Is there a way to disable non-camera motion blur on an object? Although it is animated, it's not moving much relative to the camera, so that could be a good workaround.

If you want to use motion blur on object which has changing topology you should enable "velocity blur" under "Sampling" sub-tab of the Render tab of geo Node properties.

That worked! Thank you chakarov!
