Adding vector blur

Motion blur really adds to your render, and can make your animation stand out from the rest and look much more realistic. It gives the fluid a sense of motion, which can make the simulation look much better! All cameras have a bit of blur when an object is moving very fast, and if it’s not added, the animation can look a bit strange. Now, we could go over to the Render panel and check the Motion Blur box, but that’s not what we are going to be doing. Instead, we will be adding vector blur!

Here, you can see an example of an animation with and without blur:

Vector blur

This is a fast way to simulate motion in the render using the Compositor! It uses vector data from Render Passes to blur the image in 2D, giving a look of motion. So, technically, it’s a “fake” blur, but it still looks great and can render much faster than a real motion blur.
