Creating a trail from VDBadvectpoints

[leohak]

probably a simple one, but still I'm not sure i understand how it works.

im advecting scattered points through a VDB vel field in a solver than i trail those points.

I'm trying to polywire the result for the render but i see only a series of points. 

what is the right way to do it?

Hi Lior,

Before your solver, you should set an "id" attribute after the scatter. In a pointwrangle, you can do

i@id = @ptnum;

Each little "seed" point will have an id, then every copy he leaves behind in the solver will have that same id. So you can use that attribute to connect them!

Then, before you do your polywire, you need to put an "add" sop down, go to the "Polygons" tab, select "By Group", and change the "Add" Parameter to "By Attribute". The attribute name will just be

id

Then do your polywire, and you're all set!
