Spektr/Lightning

Lightning is a specialized line shader/renderer, which draws electric bolts between given two points.

Lightning is part of the Spektr effect suite. Please see the GitHub repositories for further information about the suite.

System Requirements

Unity 5.1 or later versions.

Lightning only draws line segments of electric bolts, therefore it’s strongly recommended to use with a HDR bloom image effect to add glow around the line segments.

The Lightning shader only requires Shader Model 3.0 and might work on mobile GPUs. However, it's not very practical to use with previous generation GPUs, because it’s difficult to use without a HDR render target and linear rendering.
