You can click on the HDR Canvas to pick the direction and set the length of the blur - it's that easy. Can penetrator can be cheap! Meeting reminder letter. I like the idea behind isolating the blur as a seperate motion vector pass to be used by the compositor ( via the 'real smart motion blur' plugin) but the shaders built for that plugin do not work with the fluids volume shader. JIRA TICKET: RPRMAYA-2238 PURPOSE: Support GPU cache Maya nodes (alembic files). And if this motion blur works like the shapekeys workaround, it might be comparing the current frame with both the previous frame and next frame. My first guess would also be that Blender is using the vertex index of the meshes.

Maya alembic motion blur If I animate within blender, adjusting the shutter time works accordingly.
