What do you want to achieve?
A real-life like laser beam, that stops when it hits a wall or a surface
What is the issue?
I can’t figure out how to
What solutions have you tried so far?
Using a beam object that moves the second attachment wherever the mouse points, but the beam is not really round from some perspectives
That is because when you use the “beam” its displaying a texture, you may want to look into using trails instead with lifetimes attached:

This is what I use for my laser beam bullets.
you can use runservice heartbeat to make it as accurate as possible within frame updating.
raycasting to make it STOP at a part.
