==3D Trails==

A '''3D Trail''' is a trail that moves in [[3D Space]]. The footage often remains a 2D plane, ~~however it~~ can also be ~~3D itself (which~~ is ~~also very resource-intensive!), which when done is often known~~ as a '''4D Trail'''.

A '''3D Trail''' is a trail that moves in [[3D Space]]. Popularized by players like {{mafar}} in the late 2010's, the technique became ubiquitous with the style at the time - especially players who specialized in effect-heavy works.

There are two major types of 3D trails. The first is basically an extension of a 2D trail moving in 3D space. The second is more of a "pop-out" of a particular element, which can be seen below. These two can be also be combined as you see fit.

While the 3D-projected footage often remains a 2D plane, 3D elements can also be trailed; this is sometimes referred to as a '''4D Trail''', due to it following the timeline of an object moving in space.

==Echo Trails==

An "echo trail" can be best described as a "comet" - the main layer moves around, with a trail of some sort following shortly behind.

[[File:Echo trail.gif]]

For this example, the "Echo" effect in [[After Effects]] was used with ten repetitions, and a decay of 0.9 (meaning 10% of the transparency fades away per frame).

==Standing Trail==

'''Standing Trails''', usually done manually, ~~consist~~ of ~~instances~~ of ~~the~~ layer ~~being repeated so many times that it forms a trail~~. Famously popularized by {{Sid}}, they often can be dozens, if not hundreds of layers long.

'''Standing Trails''', usually done manually, have the important distinction of no keyframes; the position of each layer is completely static, or "standing". Famously popularized by {{Sid}}, they often can be dozens, if not hundreds of layers long - a very arduous process! Editors with scripting libraries can use [[Expressions]] to make this process a lot easier, as you can simply have each layer's position a certain distance, times whatever layer it happens to be.

Creating a 3D trail is similar in process to a 2D one, however you now have to repeat the layer through 3D space. As a result, usually you must do the effect manually as traditional video effects do not apply to 3D space.
