Hi recording-team,
Particles can fade out by setting up an age-based gradient for the Alpha channel used inside the material.
Let me try again: The MoGraph Tracer does not have any idea about time, more precisely, age. Without this information, fading is not possible.
The workaround initially shown can't produce the same color on a single spline. So I created a new material, with a different color that is supplied to every single one in the same way.
So, you say that X-Particle has an option for Splines to fade out based on age?
If you like to suggest features, please do so here: "Share your ideas."
