Previously,I posted an aricle that advecting particles by using smoke.
this is another Method of that.
The previous article, I use “POP Advect by Volume” Node, in order to move the particles by the smoke.
You can do the same thing using VDB.
Using VDB Advect Points(SOP) Node, you can advect point by using VDB.
Converting the field to VDB, Vel field has become to three scalar VDB(xyz), so I use VDB Vector Merge(SOP) to create one vector VDB.
Features of this meshod is processing of advection is SOP, and precess is light.
That’s all for today.
