I’m not entirely certain about this, but from what I’ve seen for Unreal, many artists use meshes for lasers instead of actual beam emitters itself. For example, three flat elongated faces with high emission, then given high movement in order to give the illusion of a laser. I’m sure a cylinder could also probably get the same effect. I’m still new to using meshes in FX, so I’m not entirely sure, just going off of what I’ve seen.
Yoeri -Luos- Vleer does a really good job at showing this in his video about the Vulcannon. Its not a tutorial sadly, just a speed create, but its awesome none the less. Heres the video:
Edit: The main portion I’m referring to in reference to the laser is at around 6:40.
