Line Renderer Component

Line Renderer Component

Draw and manipulate lines in Unreal at runtime with ease!

Line Renderer Component allows one to easily draw lines with thickness. Implementation is based on the engine BatchedLines with the modification to control how vertex buffers are filled with user data. This allows to have flexible system to control which lines should be shown, deleted and so on.
