vdb from particles inner core [SOLVED]

[sipi]

hi,

I scattering points on a surface then I use vdb from particles on them, and finally convert the result into polygons, but I got an unwanted inner core geometry. How can I get rid of that procedurally?

Connectivity SOP -> Measure SOP (Volume Per Piece based on class) -> Blast SOP (@volume<=0)

Thank you Anim for the quick reply!

It seems to me that this method unfortunatly doesn't work well with other geometry, I tried with a pig and the result isn't accurate.

maybe this? not exhaustively tested tho...that's your job.

right, the connectivity and blast should work on the same type, either both point or prim, I updated the setup in the pig scene

Thank you very much Anim and Noobini! Both solutions works like a charm.
