I am actually creating a small project and I do not know how to make the 3d particles transparent. After watching some tutorials and reading some documentation I am not able to get the effect that I want.
I want to make the trails of a boat, I setted 2 particles nodes that creates Quad Meshes moving out of the ship and growing through time. Now, I want to make them smoothly disapears through time, but when I change the parametres in the Albedo category to make them transparent it just do not work.
I have set in the draw fasses 1, the quad mesh material with the flag "vertexcoloruseasalbedo" on, and I have created in the proccess material a color gradient that go from a white color to a transparent one but from some reason the particles do not make transparent through time. Changing the Alpha color in the Albedo part, I am not be able to make the particles transparent, I do not know why. I have created a small video in order to show you the problem:
I am using Godot Engine v3.3.4 stable official.
I want to recreate this kind of behaviour in the particles (5:00):
I am new in 3d particles and for sure there is something that I am missing, but I do not know what it is, I hope you can help me.
