hi,

i want to use vertex velocity as a normal on mesh.
i didnt find a straight way to get the velocity from a vertex so i did it through chops. this becomes pretty slow if i have lots of points and frames.

what would be a better way to get the velocity?
somehow storing previous point positions and calculating vector from those?

if i did want to use the chops approach how could i optimize it so that i didnt have to cook the whole timeline to each channel?

thanks!

us e the trail SOP to compute velocity, and then point SOP or attribute SOP to remap v to N
