Using the VectorBlur node

3D motion data can be used to drive the VectorBlur node directly, and there are two ways to do that. Let's take a look over here. What I have here is a checkerboard hooked to a card. If we switch to the 3D viewer and we have our camera--so this little 3D scene has motion on the card, which we're going to use to create motion blur.

Back to the 2D view. We hooked the viewer up to the scan line render node, and then if we check our channels, we now have forward motion channels. And it came from the camera and the card and the ScanlineRender node. If I open up the ScanlineRender node, you can see here on the Shader tab, this is where the ScanlineRender node has created motion vector channels: forward, U, and V. We'll close this and the 3D camera.

So at this point in the data stream we have motion UV data, so if I hook up viewer2 to the VectorBlur node, open up the VectorBlur node, we can set the channels for RGBA, set the UV channels for forward, and there we have it. You now have...
