Working With 2D Motion Vector Blur In Arnold

Rendering motion blur in 3D is something that can drag down render speeds easily. Luckily, you don’t always have to render out a costly and full-on motion blur every time. Sometimes rendering a faked or 2D Motion Vector blur will work in a jiffy.

Here, Arvid Schneider discusses the advantages and disadvantages of using vector blur when rendering in general. Arvid also walks through rendering 2D motion vector blur with Arnold in Maya.

In the end, you can render a 2d vector blur pass, or AOV, that can be used to add the blur back in any compositor. Arvid shows how to composite the blur AOV in Nuke, while offering tips for getting it looking its best.

If you haven’t been following along, the latest version of Maya ditched Mental Ray in exchange for Arnold. Arvid Schneider has been helping get new users oriented quickly with Arnold with a series of 100-level tutorials.
