Geometry motion blur is not supported on meshes with changing topology - such meshes will be rendered without the motion blur

This message occurs when motion blur is enabled and scene contains meshes with animated changing topology. These meshes will be rendered without topological motion blur (they will still render transformation motion blur though). It is planned to at least partially remove this limitation in future.

Possible causes:

Presence of mesh(es) with animated changing topology in scene with enabled motion blur.


Unfortunately there is no known solution to reliably compute topological motion blur on meshes with changing topology, unless motion vector data were computed in advance and stored within mesh vertices.
