Draw, created brush, small explosions from lightning in spheres. Select your brush and on a new layer (this layer must be the uppermost), draw where lightning touch the ground with the spheres. Change the Size and Angle of the brush (Opacity 100%) to make it look realistic. The closer to the viewer, the more I did the size of the brush.
Merge all layers with lightning in one layer (select layers and use Cmd /Ctrl+ E or Layer > Merge Layers…). Now duplicate the glow effect with little lightning in the group “Interior” (Hold Option/Alt and drag effect).
Duplicate this layer twice (Cmd /Ctrl+ J) and change the Blending mode of both layers on “Subtract”. These layers must be below the layer with lightning. Set the Opacity for each layer as shown in Figure.
Layer with Opacity: 15% need to Flip Horizontal (Edit> Transform> Flip Horizontal) that texture not look to the same type.
Select both layers. Use the Free Transform tool (Cmd/Ctrl + T or Edit > Free Transform) to resize the layers larger than the size a working area. So we will create a larger texture in the picture. Similar to blood vessels of the eye or energy flows.
Add a layer mask to one of these layers (when make one layer simply duplicate the layer mask to the second layer) and used Brush tool (B) to remove effect from the center of image. Combine layers with lightning in one group “lightning”.
Begin to create the effect of radiation on the edges of image. Create a new layer under group “lightning”. Fill layer white color ( press D to set the default color. Then Cmd/Ctrl + Del to Fill). Convert this layer for Smart Filters (Filter > Convert for Smart Filters).
“Convert for Smart Filters” are very useful in work. Especially when you are experimenting with effects. You can edit settings applied effects.
First add Fibers to create a texture in the form of strips, so the future texture will look more interesting. Go to Filter > Render > Fibers… Make settings like shown in the image. You can select a different combination by pressing “Randomize” (settings will not change).
Now noise. I decided that the noise would go well with the outside atmosphere and simulated noise and radiation. Go to Filter > Noise > Add Noise… Make settings like shown in the image.
Do not worry, that everything is covered with texture. Change the blending mode to “Overlay”, set Opacity: 60%.
Add a layer mask to this layer and used Brush tool (B) to remove effect, leaving it only at the edges of the image.
Duplicate this layer (Cmd /Ctrl+ J) and change Opacity to 62%.
Repeat steps 4 and 5 for first texture layer to create 3-D effect on texture. So it looks more interesting.
I decided to add more noise at the edges of the image to make sealing texture. Create a new layer below the layers with the texture. Use a soft brush with Size: 500px and white paint over the edges of the image.
Convert this layer for Smart Filters (Filter > Convert for Smart Filters). Add a filter “Add Noise” (Filter > Noise > Add Noise… ). Set the settings as shown in the figure. Be sure to set the checkbox to “Monochromatic” to make noise in black and white.
