Built-in 3D mesh trails

[KC098]

There's a lot of addons that accomplish this, but often not optimized or doesn't have the functionality you hope for.
So why not integrate it? It has become something very useful lately that not a lot of people give too much thought on.

Godot 4.0alpha already supports particle trails with GPUParticles (in both 2D and 3D). These rely on the RibbonTrailMesh and TubeTrailMesh primitive meshes, which have their own skeleton and can also be manually skinned to create 3D curved meshes.

How does it compare to like Unity's 'Trail renderer' component? For the looks of it, sounds like it needs more setup to achieve the same effect.

You can use local coordinates for Particles and control length of trail with initial velocity. It's close to unity Trail system.

i would say its far from close to unity...
