A simple glowing trench model to add more variety to your scene. Detail is kept low-poly to not heavily increase the overall poly-count as these type of trenches get fairly long when it comes to animation.

Use the array modifier to control the trench length.

If you would like to have a more "death star" like trench simple adjust the "glow wire" material and the lightning.

File doesn't use compositing. If you are using this file with other models that use compositing with a glare node e.g. for glow lights consider using different render layers or render passes.
