Thanks and the rain effect is firstly a set of gradients, gray or light grey at about 50% transparency placed around the figure. Then you place the speed blur effect from Backplane-Auras, set also to various light greys, also transparent, maybe more so. You then add more of the aura with varying layers and some different angles. I hope this helps.
