so I have a rock break apart with reactor fracture, then I have the pieces begin to break down with a gradient ramp opacity and begin to spawn particles to appear as if its all breaking down to dust. The pieces are moving along in "water" (just a moving uvw map) using reactor wind and I need the particles to spawn moving at the same speed as the chunks and slightly accelerate with a little variance, moving in the same direction in the "water"s flow. Speed by surface almost works, but i cant get it to only move in that direction. Any ideas?
