I’m having an issue when using the line material and when I set the fade in and out parameters in the render settings. For some reason the particles aren’t using the alpha when fading in or out, instead they fade to black, independent of background or particle colour. I’ve tried changing the render settings to see if there’s a bad setting but I haven’t been able to resole this issue.
Doing my due diligence for anyone who finds this post and is looking for a solution. In my case there seemed to be a bug in the specific version I was using and simply updating to the most current version solved my problem
