[Solved]Particle system. Fade-in, fade

How to implement fade-in and fade-out particle texture? Managed to adjust fade and the appearance of particles with the parameter in the material Emissive Map - color vertex stream. When placing a texture in the Emissive Map settings Updaters - color animation not working. Help to understand with a problem!
Applied the material to understand the problem.

I apologize for the poor quality Gif images. The maximum allowable file upload size should not exceed 3 MB. Cut as I could :disappointed_relieved:

Managed to achieve the desired result, by adding the parameter update and edit the curves color.
