Nope, haven't tried that. Let me know if you find something =)

Yes thank you arvid. meanwhile Meanwhile I've got it too. Did you have any experience with the mental ray motion vectors and nuke. That's the next thing I want to test. T

I made it work with the standard tools, and it's quite near reelsmart but rsmb still looks a bit nicer. I also got some edge artifacts, some of which could be fixed with a tiny edgeblur of the beauty pass.

You have to set the vector-pass read node to "Raw",
then you have to use a Copy-node to copy rgb.red to forward.u, and rgb.green to forward.v,
then use the VectorBlur-node, set add u/v to -0.5 (to normalize), the multiply value to the value lmv shader reports (max displacement) and offset to -0.5, and method to forward.

Should work. =)

Hello everyone,

 

did anybody have success with post-motionblur using nuke? I know the Reelsmart-plugin for nuke works quite well. But is there a possibility to use standard nuke nodes and xsi motion-vector or lmv passes?

 

Thanks

 

Sebastian
