+description="A simple line renderer for Godot 4.0, useful for rendering cylindrical volume such as lasers, trails, etc. Based on the Godot 3.0 version by @dbp8890 at https://github.com/dbp8890/line-renderer ported by @LemiSt24, which is based on the helpful C# implementation by @paulohyy at https://github.com/paulohyy/linerenderer and added some additional features such as UV tiling."
