Hi all,

Say I have an object plugin generating an extrusion along a path. 
The path is a BasAarray of vector positions.
If the path is animated, say by applying a sin to the x position of the vectors over time, motion blur is not considered on the resulting geometry beyond frame 1. This anomaly is visible in the standard, physical and Vray renderers. 
If I apply a Motion Blur tag to the object, it renders the first 2 frames (0 and 1) and gets stuck on frame 1 for the rest of the rendered animation.
Any clues on how I can force the motion blur calculation to update on deformed procedural geometry?

I solved it by caching the effect.
