Beam particle refraction not affecting the world

Hi,

i have an easy material with some refraction in it.
I want to have a beam particle using this material!

Beam works just fine but the refraction does not do anything! It jsut seems that it is not there or so…

What am I doing wrong?

I’m having the same issue in 4.15. Is refraction simply not working with beam particles?

YES, I CONFIRM THAT, IT DOESNT WORK also ribbons doesnt have refraction as well

it;s interesting there is some work with normals, but it’s tiny compared with refaraction effect on mesh particles for example, btw it’s appeared niagara beams/ribbons doesnt have this issue
