Use the sliders and options to change the appearance of the lights. Ray March is the amount of steps each point will take before being rendered, the higher the value the longer the ray will last. Transparency will affect how transparent the ray is, lowering it will cause the ray to end faster. Light Range will limit how far a ray will be able to go before ending, lowering this value will increase the performance, be careful having this value high, as even if the ray is no longer visible it is still being rendered and calculated. The Ray Density is how many rays are rendered, a larger value will cause less rays to be rendered therefore increasing performance.
