My skybox contains a laser, stretching from the top of the non-skybox height to the top of the skybox height. It's rendering in-world OK, but it fades out part of the way up, like so: I should mention that the skybox is unusually tall; about 7500 Hammer units. This is necessary because I have the moon as a brush within the skybox, and it needs to be very high up to avoid noticeable parallax when the player moves around the level. Is there anything I can do about the laser render issue? I'm assuming it's some kind of draw distance issue, but the moon is rendering fine.
