However we do not have enough licenses of RSMB for the renderfarm.
When I plug the VrayVelocity pass into an RSMBVectors node (from the makes of Reel Smart Motion Blur) the image is motion blurred correctly. On my current job, I am receiving Vray Velocity passes that don't seem to play nice with the built-in VectorMotionBlur tool, the image is just blurred uniformly. I plug the rendered G-Buffer Velocity pass into Fusion's built-in VectorMotionBlur tool and everything works just fine. Furthermore, you can use it with any type of deformer object.I am a 3ds Max / Vray / Fusion user who has often rendered an embedded exr Velocity pass out of 3ds Max using the G-Buffer. The major advantage over Sub-Frame Motion Blur is the fact that no intermediate frames need to be rendered, greatly reducing render times. This makes it possible to blur rotating motion as well. Several samples are calculated and distributed along the path.
When rendering VMB, the path of an object between its start and end point is taken into account. Naturally, the blur will therefore be even greater.
An angle of 360°, for example, means the shutter rotates a full turn over the course of a single frame, exposing the film for a portion of that time and therefore creating full motion blur between two sequential frames.Ĭinema 4D takes it a step beyond realism by allowing you to use much larger angles than a normal camera. Traditional film cameras have a rotating shutter, where the shutter’s angle determines how much blur can be captured onto film. VMB takes a very different approach: based on the physics of a traditional analog film camera, VMB is based both on the object’s speed as well as the shutter angle of the camera itself.
Next to Sub-Frame Motion Blur and vector motion blur (VMB) gives you an additional means of blurring moving objects.
