Beam particle doesn't face camera after setting tangent and source strength
The screen alignment for beam particles doesn't work after settings source/target tangents with source/target strengths greater than 0. The beam seem to be fixed and won't rotate towards the camera, so if you view the beam from the side, the beam will become thinner and nearly disappear. Is this by design, a current limitation, or just a bug that's never been fixed? This post from 2 years reports the same issue: https://answers.unrealengine.com/questions/128051/tangent-beam-and-screen-alignment.html
I can't imagine that this is by design, since beams look terrible when not facing the camera. And I also can't imagine that it would be that difficult to fix, since it just requires proper updating of the particle geometry. It's been a while since the initial bug report, so hopefully this issue gets addressed soon.

The bug that was entered by Eric K., UE-5049 was returned as By Design by the engineers. Taken directly from the engineer, "This is expected behavior, beam emitters have always worked this way." This is just simply how they work, and we do not intend on modifying the current implementation as of now. This is all the information I have in regards to the issue, but if you have further questions or need additional assistance, please let me know.
