Hasta La Motion!

I think my brain is going to explode. I’ve read so many posts about people’s solutions and problems with Motion Vectors in nuke, but I can’t seem to find any that actually works for.

My scene is a tentacle moving around – as well as a camera moving around it. I am trying to export the motion vector data from maya to do the post compositing motion blur but I can’t find a suitable shader to apply. I tried the lm_2MV shader with no luck, tried the mv2DToxik but am getting very weird results, tried the 3d and normalized 2d as well.

The problem with the 3D blur is that it is giving me more than just Red and Green. The problem with the normalized 2d is that the values are all within .001 of eachother inside Nuke (the image looks completely yellow) and it has a grey background, which I suppose can be matted out with an alpha. The mv2DToxik pass is like a rainbow on crack.

What am I doing wrong? Maybe someone out there has figured out a good way to get motion blur inside of nuke from Maya2010? RSMB doesn’t work well for my scene either.
