shawn_kearney Posted September 19, 2016 Share Posted September 19, 2016 (edited) I've always been a bit confused about how to get robust, user-defined advection into a simulation. Thus far the best method I've come across is to deform a plane and use the dot product between the normal and the initial velocity vector (sorry if my phrasing here is not accurate), plug this into the velocity attribute and generate a volume to use within DOP. And this does work pretty well, is very efficient and straightforward. Advection follows the geometry pretty much as I expect it to. But I often find my solutions are seldom the best practices and later discover it falls short in some major way. How do you go about "directing" your simulations?
