Use Marble (marble) filter to do lightning effect

With the eye CANDY 4000 filter, we found that many of the cool effects are no longer patented by PS. FW combined with the EC filter can also achieve many unexpected effects.
Let's take a look at these two simulated lightning, okay? Would you say: Is this FW made?
　
OK, let's take a look at how to use the filter component in Eye CANDY 4000 marble (marble) to make lightning effects.
1, new canvas, 500*300 size. Then draw a rectangular box of the same size in which the color fills at random.
2, select the Rectangle box, perform the special effects of the eye CANDY 4000 filter Marble (marble), open the Marble Filter Settings window.

3, in the Open Settings window, the parameter settings as shown below, note that, by default, bedrock color is white, and vein color is black, here we set exactly the opposite.

4, look at the window to the right, is not vaguely a little meaning. We can randomly generate a lot of results by clicking on the "Random Seed" button at the bottom left. Because the above parameter value is fixed, so just "lightning" movement direction is not quite the same.
5, OK OK, we saw the full of lightning appeared in front of the scene. No hurry. We don't need that much lightning, one or two branches is enough, select the object, press the keyboard shortcut ctrl+shift+alt+z, convert the picture to a bitmap, and then use the Rectangle selection tool to select a portion of the diagram:

6, immediately followed by Ctrl+shift+i, the graph will be reversed, delete the selection, you can get a part of the "lightning" effect.
7, the black and white effect of course not enjoyable, we also need to adjust the color, select the menu "Filter >>> adjust color >>> hue \ Saturation" command (also can use the Curve tool), open the Setup Panel.

8, do the following parameter settings, of course, remember to select the "color" option OH.

9, OK, set up, look at our production of different colors of cool lightning ...
