hi,

im advecting particles with smoke and rendering those particles as points.
i would need proper normals for the points for shading.
my plan was to create sdf from the smoke density and from that calculate normals for the points using vopsop.
my problem is really simple:
how do i get the smoke density to sop level so i can calculate the sdf using iso offset.
is that the way to go or is there something more straightforward?

thanks!

quite often when u present your problem to others it helps yourself to see it more clearly.
obviously dopImportFields was the node i was looking for.
