Particle Spawn, fading brightness

Continuing my VFX journey, I am stuck trying to get particles to “slowly”
brighten upon their generation. I am using a bezier curve to slowly increase
the brightness, but doing so affects all particles at the same time. How would
I go about applying the bezier curve to just the newly spawned particles?
Thanks

Figured it out. GetParticleAttribute as Age.

Thank you for the feedback :wink: Regards, Boris
