how to make a light circular

i tried all the lights and they either lit the intire terrain or the light made a weird hexagon. i just want a circle on the terrain to be lit. I tried forcing pixels and vortex but nothing changed. if you could help me with that that would be great!


It all depends on what platform & what graphics emulation mode & what GPU you're using. If you are on a platform/emulation/GPU that is capable of doing per-pixel lighting, then putting a point light should result in a circular illumination.
