Hi,

I have been trying to use normals to drive particles velocity in Houdini 13.

It works when I use the “Old” pop network but when I use the current one
nothing happens.

Could anyone please shed a light on this?

Many thanks,

Richard

Set your velocity (v) to N before creating the particle system.

Many thanks,

hmmm… took a look and did not figure out how to do that.

What I did was to put the points operator in the SOP, tweak the normals there and then get the POP to read it, is it this what you meant?

Once again thanks,

R

one of the ways to do that is to append PointWrangle with VEXpression
@v = @N;
to your geo prior to sending it to POP DOPs

Thanks a million.
