    Yes, theoretically is in that way, but in practice people tend to do this in their final compositing project, and there it might not be the same by depending on your CM settings. In such case your...

    Here the backward node setup exactly match up with what we got when using negative mblur.

    Look, this is the RSMB result with positive mBlur (original node setup):...

    Glad it's helping!

    For backward vectors I would try this one:

    in the case of the node setup you are using, it would be something like this:

    If by 'backward' motion vectors you mean negative motion blur as Cardboard is pointing out, you can also invert X,Y vectors in DP filter. At least works with RSMB node setup.

    Danner, the aliased edges seem to be an issue for Vector Motion Blur node in Fusion, so you might render at double/quadruple (no AA) and resize or you can render as usual and try by using a bit of...

    Agree with Greenlaw, RSMB sometimes work better than native solutions.
    And talking about options, a vector motion blur option for LW is also DP VectorBlur:

    For alpha-enabled layers, same alpha has to be applied for vectors image as well. Just pre-compose your RSMB vectors image with the convenient alpha matte layer.

    raw-m, haven't noticed jaggy edges with RSMB. At least my sample image has very low AA passes - around 5 or so.

    mewnow, concepts have been already proven in that thread.

    As mentioned before, you need to scale down the motion vectors before exporting for 16-bpc. i.e. in Ae you could go in this way:

    Or in DP Filter...

    I think it makes sense blue channel is not taken into account, seeing that only Red and Green channels are used for X and Y vectors. Anyway, if it works and it's simpler... :)

    RSMB indeed works in...
  11. Maybe you are getting different color scheme...

    Maybe you are getting different color scheme because your alpha should be set to (copy) as well. though glad it's working fine!

    My setup has 3 solids because it tries to conform exactly to RSMB...

    Cardboard, I'm just a user :) If we notice, the article backs up the solution you are providing. Since the only way to get (non-physical) absolute blacks in average viewing conditions as he wants...

    Btw, Denis updated recently DP Filter.

    Erikals, It looks pretty similar. Interesting experiment, btw!

    Scott, Thank you for the video! I've realized why I was getting the blue and purple result. It was because I was using RGB=0.5 for...

    Yep, in both, HDRI3D magazine (2007 article) and here. The trick has been around for many years. We used to use it for gamma correction with FPrime but it can be used for proper colorspace...

    They talk as if they were referring to direct usage of motion Vectors with RSMB in 16-bpc (integer) image. In such case, we can not use them directly, we need to map them and scale them (either in LW...

    Well, when I sent the DP Nodes technique to RE:Vision Effects 8 years ago they were very thankful by the setup and results. Guess you might have misunderstood what they said about 8/16 bpc formats...

    ...and all your results will be clipped, which the proposed method tries to avoid. This is, getting nice AA and still keeping HDR values.

    Just in case, rendering at higher resolution without AA and then resizing down may help for noisy results, but it won't help much for artifacts due to super bright pixel values.

    Hey Maxi!

    How are you doing? some nice examples there!

    Haven't noticed render speed improvements in my scenes here. Idea was just to solve artifacts in reflections, so we could skip it in...

    Yep, as gar26lw says, DP Mask Objects/Surfaces nodes can be used in DP NPF.
    You can plug them in Scalar Global Buffer or you can also plug 3 different masks in RGB Color Global Buffers (so a single...

    Why do you think I didn't reference the node setup you are trying to use? It was because if you notice, at the beginning of that tutorial it says:

    Maybe you need to enable Multithread/Persp.AA? this allows AA compatibility with the pixel filter.
