Particle trail in 3D?

Hello, I would like to ask whether there is a way to project particle trail in 3D as it is possible with the particles themselves when they are in “Align to Direction” mode. I am working on a 3D object of a window that has a particle effect of raindrops falling down the glass and leaving a trail of water. The particles are now flat on the surface but the trail is still following the camera for its direction, which ruins the illusion when watching from different angle.

I don’t know of a good way to do this.

The only way I can think of involves some scripting and additional performance cost.
That is, to use ParticleSystemRenderer.BakeMesh and BakeTrailsMesh, which will allow you to pass a camera in that is directly above the effect, looking down at it. Then you can render the baked mesh without the trails re-orienting towards the viewer’s camera.
