Join Mark Lefitz for an in-depth discussion in this video Adding motion blur to the wheels, part of Photorealistic Lighting with Maya and Nuke (2012).
Using Photoshop, we open up our tiff file that we just rendered from Nuke to make…our final adjustments, and the first order of business is that we need to add…some motion blur to our wheels.…I can do this in Maya, but it will increase render times, and is probably…not as art directable.…So, I really prefer to do this in post, typically in Photoshop.…So now that we have our rendered version in Photoshop, let's zoom in, and…concentrate on our back wheel first. With our Elliptical Marquee tool selected,…let's eyeball the center of the wheel, and holding the Alt key simultaneously and…our left mouse button, we're going to create a new ellipse here.…
