#NUKE 10 TUTORAIL HOW TO#

Lets go back to maya for the explanation. The alpha is necessary for the proper edging of the motion blur.ДЄfter this setup however there is no motion blur. What we need to do is copy the R and G from velocity pass to forward u and forward v of the rgb beauty using copy node.ДЇor motion vector, set the uv channels as forward, multiply to 0.5, method to forward and check use rgba.alpha Lets bring this into nuke and setup the vector. The settings for proper motion blur should be duration of 0.5 and interval center of 0.0 If you measure the value of the Y vector, you can see 1.0 which means the cube is indeed moving properly on Y.ДЇor reference I have rendered an image with true 3d motion blur out of vray. The reason I did it this way is that I know what to expect in motion vector result, one should have more or less pure X (red) color and one should have Y (green).ДЄt first I have just simply added the velocity render element to my scene and rendered it. I have created a scene where two cubes are moving, one in Positive X and one in Positive Y.

I will try to cover the setup as well as explain why some of the problems occur and what to do to avoid them.

Often there are questions on the web on how to properly output vectors for 2d motion blur and often people have strange results. This setup is done in maya but also works for 3ds max. I thought I'd post this really quick tutorial about passing velocity data from vray to nuke.
