Render Passes with Cycles

I rendered out a multilayer .exr
Then I careated an input node (image) in the compositor. There are only three sockets though. I will still need other ones such as the speed so that I can created motion blur. As of now there’s only a z. Am I missing a step?

Did you enabled Vector before rendering/saving?

I did. I clicked all of the boxes and even the direct and indirect. When I upload what saved onto my desktop all I see is 3 passes. Image, Z, and another. May have been alpha.

Are you sure you actually saved the file as OpenEXR or OpenEXR Multilayer? With OpenEXR all you’ll see is Image, Alpha and Z outputs. For all other passes use the Multilayer
