Dear all,
I have issues to create motion blur in nuke using render from Corona.
I render the velocitypass, put it in a VectorBlur node in nuke but the motion blur is wrong.
I use a shuffle copy berfore the VectorBlur , the shuffle is set like this : Red channel from VelocityPass is U, Green is V
Do you have any process to make it properly ?
Kind regards !
No experience with Nuke here, so can’t really help, but have you tried changing gamma? (up and down, so setting it to 2,2 or 0,45)
Different software expects different things - some expect Camera, some expect World, some have an offset required as they run from 0 to 1 or -0.5 to 0.5, some have a multiplier because they run from -1 to 1, etc. Unfortunately, you will need to find what Nuke expects from their documentation (or just experiment with the various settings til you find what matches Nuke’s expectation). Our tutorial covers it for Fusion (and what it expects is what Corona produces by default, as it happens) but mentions that other software will have different needs - https://www.youtube.com/watch?v=6Hk2jhbQTuI
Thank you !
yes i already whatch it, I’ll play with the multiplier that’s a good idea. Thanks !
Let us know what you find - also, maybe a forum search for “Nuke” will turn up someone already with the answers 
Thank you 
I’ve try the research on the forum but nothing close to my probem. I’ll let you know !
