Motion vector not working

[nemsi 7]

Hi guys,

I can't make motion vector working in my scene even with a wrangler point to activate it..

Any help?

 

Thank you.

I suppose that's because the optransform() returns identity matrices only in your case. What about using a trail sop to calculate the velocity automatically? Or use a timeshift to calculate the previous point position.

Thank you Haggi, I was looking for the trail sop but forget the name..
