I am busy creating shadows for a 3d glass box that I am working on. I want to create the shadows that the pillars make on the ground however, I seem to be having trouble trying to figure out how to blur one end of the shadow more than the other end. My shadow is a vector shape that I have drawn with the pen tool. I do not want to blur the whole shape evenly, I want to blur one end more than the other end. Kindly see my screenshot below. Any help would be appreciated.
What about to draw the forms in Illustrator and then copy/paste them and blur in Potoshop? There you will have smart filters or Blur Gallery which allow you to control the blurriness much more free and precise.
