Done in real flow, rendered whit mental ray in 3ds max and composit done in ae. Just a low res test and low res fluid.Wanted to test the use of velocity pass from fluid in ae to obtain an acceptable motion blur but in the end could not use that because of the low resolution fluid simulation and in the render pass velocity pass was taken from low poly mesh, even whit turbosmoth applied on fluid sim mesh.
