I need some help with 3dsmax and Nuke and the vector blur.
I am rendering an animation with mental ray.
I have added the “velocity” channel in the render channel (saving to OpenEXR file sequence (16bit floating I think))
I Import all this to nuke - shuffle it into the motion pass of my beauty pass (png sequence) but when I add a vector blur node all it does is add a blur which looks like full picture motion blur from the bottom right to the top left.
Nuke totally seems to ignore the pass.
Now my question: How do I fix this?
Do I have to add the MR vector blur export material thingy from mental ray into the output of my camera in the renderer Tab?
I seem to get good vectors on my particles but the background, the static geometry in my renderers are always grey - they don’t seem to have motion at all.
(couldn’t find any tutorials / any thread on this topic (only really old ones which are not of help) that’s why I am writing here)
