Niagara particles RTX black shadow how to fix?

Hello all
Running into a snag with 5.1 and translucent shadows in niagara. I’m using Lumen with RTX. I found that turning off a setting in the skylight raytraced fixes the harsh shadow in the material but it returns in niagara for some reason. Anyone know what this issue might be and how to fix it? Before the mat and the effect matched in look. Now I want to have softer blend of the material in the particle.

Hello,

I am not sure if this will help you, but i think i had the same issue. I solved it by going into my project settings, then to Engine → Rendering and the to turn off “Enable Order Independent Transparency (Experimental)”
