VDB velocity from BIN particles


Recommended Posts



firstly I will say i am a bit green with houdini, so be gentle :)


I am trying to get some air particles out of a Real Flow BIN particle stream. I am not sure how can i get the velocity from them in to a VDB so i can use VDB advect points...


any pointers to tutorials appreciated!

doh! thanks...that did something ,  but i am hardly getting any movement on the particles....time to re watch some tutorials.


 vdb advect points may not be doing what you think it's doing .. ie. it doesn't hold any state or do a simulation, it just moves points along.  There's some good examples of it's use here:  http://www.openvdb.org/download/ 


 get the file "Houdini Examples".
