1) Smoke effects have been tampered with in the latest update. Smoke effects need to be reverted back from previous updates. Smoke effects start off normal when a vehicle is burning, but abruptly reduced into a tiny smoke trail which doesn't look normal. The smoke trail tries to build back up but randomly is reduced causing an overall visual glitch.
** The original smoke effect looked perfect with a solid trail of smoke that builds up and gently disperses in the air.
2) Helipad lights randomly doesn't produce a glow it used to have in the past. The helipad lights blink with a low light and no glow which makes them useless for spotting. Sometimes the helipads produce a light and glow, but for the most part don't when you start or restart a mission.
** Originally the helipad lights always produced a glow and solid lighting effect which was very useful for landing and overall spotting from a distance, especially at night.
3) Burning Barrel fire and campfire burning lighting is too low. Light source is high above the burning object. Light source must be lowered to the actual object to give off a proper ambient lighting effect.
