It might be very helpful to post a maya 2010 scene with render passes set up correctly, and also an AfterEffects CS3 file linked to the fooatge, and set up with reelsmart applied correctly…pre-comps and all. Cant get RSMB vectors to work using my own Maya scenes…follwed this and other tutorials to the T. The RSMB Blur is huge and diagonal set to 1024.

you could try to apply the post motion blur to the depth pass also.. and then use that as the data for the DOF.. Not sure if it would work in a quality way though.

Great post-blur info here. Any workflow advice on integrating a post DOF (from a plugin like lenscare), with this post motion blur method? It doesn’t seem to me that there is a way to integrate both without a mess.

I am currently resigned to use thefoundry’s motion blur plugin after I lenscare my compositions. Works pretty well, but breaks down fairly quickly in areas of high movement.

Allright I give the non-vector-plug-in approach a try (i’d like to maintain some control over the blurriness in post).. I’ll let know if I come up with something genius (haha) which might be usefull to you guys..
Cheers and keep up the good work!

My suggestion for that would be to either render out your motion blur in maya instead or try to use the non-vector-based RSMB plugin on it and let the plugin just try to figure out where the blur should go on its own.

hi,
Thanks a lot for this tutorial, it helped me a lot, but I´m banging my head against the wall because of this: i´d like to add motionblur to my reflection and shadows aswell.. I tried extractor, and also the ProEXR layer plugin to extract the 3d data from my background-layer where a I also aplied the normalized motion vector pass.. (with both different results, but still not working)
Thanks in advance

Thanks Jake. I got it to work but for some reason, the EXR files that contain Motion Vectors made AE crash. I made a new scene, rendered some EXRs and it worked. I don’t know exactly what I did but finally I managed to import the files, precomp and now I have glorious motion blur

It sounds like you are not compositing the alpha properly (via precomposing if in AE). I went into this a little in the tutorial.

Hi!
Great tutorial, but I feel like I’ve missed some bits and pieces since I can’t get my motion vectors to work… could you help me out? Deadlin approaching I’m afraid…

So I’m using the Normalized MV Pass in Maya 2011 with Max Displacement set to 1024 and file output set to .EXR, 16 bit half in the Quality tab. I get a gray and yellow image that, when applied, just gives me a uniform, diagonal blur.

Now I’m supposed to move the X and Y channels to the R and G channels but when I apply EXtractoR I don’t see any more channels other than R G and B. No alpha either.

What could I be doing wrong? Would be super grateful for some help
