When I animate a camera in Maya or XSI, mental ray applies motion blur only on native objects. How can I apply motion blur on Vue objects as well?
In Maya and XSI, by default, camera motion blur in mental ray is not computed using raytracing, but using scanline (to speed up rendering). This is not compatible with xStream so you need to make sure the motion blur is computed by mental ray’s raytracing engine. In Maya, open the mental ray render options dialog, and in the “rendering features” section, select “Raytracing” instead of “Scanline” or “Rasterizer”. In XSI, in the Render Manager dialog, in the “Rendering” tab of mental ray settings, select “Raytracing” as the Type of Primary Rays. In 3ds Max, scanline is automatically disabled by the xStream plug-in.
