Does anyone know if the Blue Long Spark material shown in the Particle Trail Renderer manual page is available in an existing package or link somewhere?

I don't think there's anything special about it. Just use a particle texture and set colors to blue

2 years later and I am trying to get a nice trail renderer like that… Set it to blue and no dice. I used the Mobile Assets and found a Spark that I tried.
