Wingtip trails are one of the highest impact-to-effort visual upgrades you can give a flight game — they communicate speed, turning, and banking with zero gameplay code. Unity's built-in Trail Renderer does all the work. Here's the complete setup from the video, expanded with the reasoning behind each setting.

Step 1 — Create the trail material

Make a new material named Trail and set its shader to Universal Render Pipeline → Particles → Unlit. The unlit particle shader is the right choice because trails shouldn't receive scene lighting — they should read as pure streaks of color. Pick a color that contrasts with your sky so the trails stay visible during fast maneuvers.

Step 2 — Add and shape the Trail Renderer

Add a Trail Renderer component to an empty GameObject and assign your material. The default trail is one full unit wide — far too fat for a wingtip. In the width curve, drag the first node down until the trail starts thin. Then double-click the curve line to add a second node and pull it down to zero at the end: this tapers the trail so it narrows as it recedes, which is what makes it look like a vapor trail instead of a ribbon.

Step 3 — Position and duplicate

Parent the trail object to your aircraft and position it exactly at the wingtip — precision matters here, since a trail floating a few centimeters off the wing breaks the illusion immediately. Once one side looks right, duplicate the object and mirror its position to the opposite wingtip.

Hit play and bank into a turn: both tips now draw clean tapering streaks through the air. From here you can experiment with the Time property (how long the trail persists), a gradient that fades alpha toward the tail, or enabling trails only during sharp turns for a more realistic vapor effect.
